Captain Underpants: The Video Game is a video game based on the Captain Underpants book series. The Follows the events from theBooks.

Plot
Chapter 1. George and Harold

The story begins with the school troublemakers, George Beard and Harold Hutchins, two boys who are known by almost every one of their teachers as disruptive and rude. George and Harold love to play pranks on the helpless kids and teachers at Jerome Horwitz Elementary School. They are also known schoolwide for the comic book series that they create and sell on the playground, known as "The Adventures of Captain Underpants", their favorite super hero. They have many enemies (all of them being the faculty teachers). But the one who despises them most is the school principal, Mr. Krupp. Mr. Krupp hates them, their pranks, and especially the Captain Underpants comics. He vows to get them one day ("one day very very soon" he claims). One day, the school's football team, the Jerome Horwitz Knuckleheads, is having their biggest game of the year against the Stubinville Stinkbugs. Before the game even starts, the football players, cheerleaders, and band players already experience countless problems with their equipment. Apparently, someone sabotaged the whole game. After many more pranks, the game had to be called off. As the players walk away, we see George and Harold crouching beneath the bleachers, laughing. Of course, they were the ones who did it all. They believe they won't get in trouble for it since they assume there is no proof the teachers can claim to prove they did it.

Chapter 2. Creation gone out of control.

The next day, George and Harold hear an announcement over the school's intercom. They are wanted in Mr. Krupp's office. Once inside, He shows the two boys that he set up video cameras all over the school, and had caught every single one of George and Harold's pranks on tape. After the tape is over, everyone is silent for a while. Then, George gets the courage to speak up and asks what Mr. Krupp is going to do with the video. Mr. Krupp thinks about it, and decides that he should show it to the school board or George and Harold's parents, but he ultimately decides to show it to the football team so they can see who ruined their big game. George and Harold beg and plead Mr. Krupp to spare them as the football team will kill them for the rest of their lives if they do find out the truth. Mr. Krupp decides not to show the video, as long as George and Harold promise to follow his conditions. Mr. Krupp takes out a stack of paper with countless chores and behavior rules for George and Harold to follow. He also mentions they MUST follow the list exactly; otherwise he will show the video to the football team. The next day, George and Harold spend their entire day doing chores for Mr. Krupp, behaving nicely, and completing stacks of extra homework.

After taking in the homework, George states he has an idea that can could get them out of this situation. George reveals that he had bought a 3-D Hypno-Ring which they could use to make Mr. Krupp hand them the video and forget that this whole mess ever happened. After 4-6 weeks of back-breaking labor, George and Harold finally get the ring via the mail. After purposely making themselves late for chores and school, Mr. Krupp gets them into his office and demands where were they this morning. George and Harold state they were going to show the new ring they got. George then uses the 3-D Hypno Ring to hypnotize Mr. Krupp into handing over the incriminating video. Harold replaces it with one of his little sister Heidi's Boomer the Purple Dragon sing along videos. As they look in the cabinet on what Mr. Krupp had confiscated from the boys and other people over the yrs, they discover some good stuff including the Captain Underpants comics they wrote from the previous yrs. They began to reminisce the comic books by reading. Hours later, they realized it was getting close to lunch time as they were preparing to leave that noticed Mr Krupp still in a trance, so they decided to wait and play around. They then begin fooling around with the ring hypnotizing Mr Krupp thinking he is a chicken then later a monkey. And then lastly, they get an idea after looking at the comic and George hypnotizes Mr. Krupp to act as if he were the Amazing Captain Underpants. Mr Krupp began removing his toupee and clothing and takes of the curtain tying it to his neck and he is seen dressed like Captain Underpants yelling the battle cry "Tra La Laaa!". George and Harold look at him and began laughing hard to their distress. As they stopped laughing to take one more look at him, they saw he was gone. They then heard him outside doing the battle cry again and as they look out the window they saw Mr Krupp dressed as Captain Underpants running outside into the city of Piqua. Mr. Krupp, as Captain Underpants, takes the role seriously and departs to fight crime. George and Harold were shocked knowing that they didn't give a command to Mr. Krupp to fight crime. So they took their skateboards and a few items out the cabinet to help save the principal.

Chapter 3. Doctor Diaper

They later find him at a bank. Captain Underpants confronts two bank robbers, and orders them to "Surrender! Or I will have to resort to Wedgie Power!" The bank robbers fall down in hysterics and are apprehended by the police. The sheriff isn't amused by Captain Underpants acting heroically so he gave a command and the police officers begin to arrest Captain Underpants too, but George and Harold whisk him to safety on their skateboards.

Suddenly, the crystal shop next door explodes, as two robots walk out of it, carrying a very large crystal. Captain Underpants tries to stop them, but his cape gets caught on their van. George and Harold grab onto Captain Underpants's feet, as he is dragged to an old, abandoned warehouse. A boy and his mother are at the bench waiting for the bus as the boy sees them passing by but the boy's mother didn't believe him.

Captain Underpants then crashes through the door of the warehouse while George and Harold slam into the back of the van. There they discover the evil Dr. Diaper, a mad scientist resembling a baby. As Captain Underpants was in plain view to Dr. Diaper, the robots capture and tie him up. When the coast became clear, George and Harold peak into the hole in the door (Captain Underpants created this when he crashed into it) to see what is going on. The witness Captain Underpants tied up in a chair with the robots beside him. The villain explains that he plans to use the crystal as part of his Laser-Matic 2000 to blow up the Moon, destroying every major city on earth, so that he can take over the planet.

George uses a slingshot to toss fake doggy doo-doo between Dr. Diaper's feet. Dr. Diaper is terribly embarrassed, thinking that he has had an "accident". When he departs to change his diaper, George and Harold incapacitate the robots and untie Captain Underpants. They pull the self-destruct lever on the Laser-Matic 2000 thinking that will turn it off.

Dr. Diaper, enraged at the destruction of the Laser-Matic 2000, his robots, and the foiling of his plan to take over the world, aims his Diaper-Matic 2000 ray gun at George, Harold, and Captain Underpants.

Captain Underpants shoots a pair of underwear at Dr. Diaper. The underwear covers Dr. Diaper's face, which renders him incapable of defending himself. Before the building exploded, the boys ask the Captain, "Where did you get that extra pair of underwear?" and the reply was, "What extra pair?" while Captain Underpants wore a barrel over himself (stating that Captain Underpants used the underwear he wore against Dr. Diaper, thus completely naked at that time). After the warehouse explodes and George, Harold, and Captain Underpants escape, they send Dr. Diaper to the police station and tie him to a nearby pole, so that he can't escape and the police can arrest him..

George, Harold, and Captain Underpants return to Mr. Krupp's office. They give Captain Underpants Mr. Krupp's clothes along with an extra pair of underpants to dress up like Mr. Krupp, so that nobody in the school would recognize him. Captain Underpants them gives them the meanest look to them like the boys asked him to do to look like Mr. Krupp. The boys try to figure out how to return Mr. Krupp to his normal self, but they've lost the instruction manual for the 3-D Hypno-Ring. They try several times to hypnotize Captain Underpants back into Mr. Krupp, but the methods do not work. As a last resort, George tries dumping water on Mr. Krupp's head. It works, and Mr. Krupp returns to his angry self, resolving to give the video to the football team after all though George and Harold are surprisingly very happy to see Mr. Krupp again. George finds the instruction manual to the 3-D Hypno-Ring in his shirt pocket, but he and Harold throw it away as they believe they do not need it anymore. As it turns out, the team enjoyed the Sing-A-Long video so much that they change their name from the Knuckleheads to the Purple Dragon Sing-A-Long Friends.

George and Harold go back to their goofy ways with nothing that is threatening to their lives. Unfortunately from this point on, whenever anyone snaps their fingers, Mr. Krupp transforms into Captain Underpants. Ms. Ribble is then shown snapping her fingers after George and Harold disrupt the class with their jokes, Mr. Krupp who was passing by with a cup of coffee unfortunately hears the sound of fingers snapping and drops his cup of coffee being in a trance, becomes Captain Underpants again and runs out of the school to fight crime. Harold and George hear his battle cry and both look outside to see that Captain Underpants has return once again. Much to their surprise, both respond to this with "Oh No!" and "Here we go again!" respectively as they thought it was over with Captain Underpants, it wasn't. The adventure was only just beginning.

Chapter 4. The Attack of the Talking Toilets.

Jerome Horwitz Elementary School is going to hold its second annual Invention Convention. Students George and Harold remember how at the last Invention Convention, they pulled a prank on the school that caused everyone to be super-glued to their seats. This year, however, because the winners of the Invention Convention get to be principal for a day, they decide to take it seriously.

Unfortunately, their Principal, Mr. Krupp. wants to avoid a fiasco like last year's and bans George and Harold from the Invention Convention, forcing them to stay in the study hall all day. They decide to secretly sabotage everyone's inventions in revenge after realizing that this isn't fair.

While sneaking in to sabotage the inventions, they run into Melvin, the Jerome Horwitz Elementary School brainiac. Melvin is working late on his invention, the PATSY 2000, which is a photocopier that turns two-dimensional objects into three-dimensional objects. To demonstrate, he puts in a photo of a mouse and a real mouse comes out.

George and Harold however do not believe that the PATSY 2000 can turn two-dimensional objects into three-dimensional objects. They promise not to sabotage Melvin's invention as long as he promises not to report them for what they are doing. Melvin, looking at his invention, states he promises to keep it a secret.

Thanks to George and Harold, the Invention Convention is a disaster and everyone in the school gets covered in slimy goo from the sabotaged inventions such as a dog washer shooting black ink at everyone instead of water at the dog, eggs shot from a shooter instead of ping-pongs and a sack of pudding from a volcano detector. The convention is called off and Mr. Krupp thought that he put George and Harold in Study Hall. However, Melvin Sneedly breaks his promise and tattles on George and Harold. As punishment, Mr. Krupp puts George and Harold in detention for the rest of the year. From now on they must write a sentence he wrote on every chalkboard in the detention room completely within 2 hours. He also threatens them if any of them leave the detention room for any reason before their 2 hours are up, he'll suspend both of them.

George and Harold quickly finish their detention work thanks to some rods that they created in George's dad's workshop. They then start to write a comic called Captain Underpants and the Attack of the Talking Toilets in which the Amazing Captain Underpants defeats millions of vicious talking toilets and their leader, the Turbo Toilet 2000. George suggests making copies of their new comic book for tomorrow, but Harold states they can't do that since Mr. Krupp will suspend them if he finds they had left. George states they'll just have to stay out of his sight.

George and Harold however find out there are teachers in the teachers' lounge, so that means they can't get to the copy machine. George and Harold then remember the invention Melvin made and they decide to use that to make copies of their comic book George and Harold still think that Melvin just crammed a mouse in there to fool them.

Unfortunately, the PATSY 2000 really does turn two-dimensional objects into three-dimensional objects, so the evil, vicious talking toilets come to life. George and Harold run out of the gym, but they get caught by Mr. Krupp for leaving the detention room and he declares they are suspended. They try to explain what occurred in the gym, but Mr. Krupp doesn't care or listen since they're suspended. He orders them to get out of the school for good and take their stuff with them. Before George and Harold can leave, the other teachers get the news and decide to notify their parents and throw a party in the gym for having George and Harold suspended. George tries to stop them from opening the door, but they don't listen, due to the fact that George and Harold are suspended. Once Mr. Meaner opens the door, one toilet gets out and swallows him. The toilets break out of the gym and attack everyone in the school. Thanks to Ms. Ribble snapping her fingers at a toilet, Mr. Krupp turns into Captain Underpants, who comes up with a plan to stop the Talking Toilets. George and Harold chase after him as Captain Underpants takes several pairs of underwear from unsuspecting clotheslines. The Boy who sees everything is seen again.

Once they are back at the school, Ms. Ribble is shown running away in terror from the toilets relying on Captain Underpants for help. Right after C.U. claims he won't let them hurt her, a toilet eats her as he stated his word. George, Harold, and Captain Underpants get surrounded quickly, so C.U. tries shooting some underwear at the toilets, but they just eat the underwear and only seem to become hungrier. The gang head to the cafeteria and find cream chipped beef as tomorrow's lunch. They then head outside and use the underwear as a slingshot to shoot the cafeteria food into the Talking Toilets' mouths. Since it is disgusting cafeteria food, the Talking Toilets die (but not before they spit out all of the teachers). Harold says that seemed easy, but George notes that it seemed way too easy to be true. Harold doesn't understand what he means. George shows the comic book they made and points out that everything on the front cover of the comic book was supposed to be brought to life by the PATSY 2000. Although they have seen the Talking Toilets themselves, George says they haven't seen the Turbo Toilet 2000 yet.

Chapter 5. The Turbo Toilet 2000

The Trubo Toilet 2000 bursts out of the school (He was turned to life like all the other Talking Toilets, but was previously unseen.). He is aware that his toilet army is defeated, but our heroes have no more cafeteria food so they can't use that to stop him. Captain Underpants then battles him instead. After a quick battle, the Turbo Toilet 2000 swallows Captain Underpants whole! With Captain Underpants out of commission, the TT 2000 states his next diabolical plan but George proclaims that they aren't done fighting just yet. George and Harold sneak into the school and locks the doors to prevent the TT 2000 from getting in. The duo then uses Melvin Sneedly's machine to make a super-powered robot who does whatever they say known as The Incredible Robot Plunger (Originally Harold suggested a giant robot urinal called the Urinator, but George disagreed since the writers will never let them get away with that in a children's book).

The Incredible Robo-Plunger comes to life from the machine and defeats the Turbo Toilet 2000. The duo gets their principal out of the TT 2000 and he asks what happened to the school and the teachers since everything is seemingly destroyed. Harold realizes that Captain Underpants must have gotten hit by the toilet water in the Turbo Toilet 2000 which caused him to become Mr. Krupp again. After George and Harold give his clothes and toupee back so he can dress, Mr. Krupp believes he is ruined as he will be held responsible for the mess and lose his job for that. George says they can repair the school, but they want him to cancel their detention and suspension as well as make them principals of the day. Mr. Krupp agrees to this, but only if they can do all that. After giving the Robo-Plunger the necessary commands, he repairs all the damage and takes all the evidence to Uranus with the command never to return. The teachers all believe the events regarding the attacking toilets were just a dream. In return for fixing the school, George and Harold's detention and suspension are canceled and they get to be principals for the day.

As the principals, they hold an all-day carnival for all the students and put the teachers (and Melvin Sneedly for his tattling) in detention. After telling Mr. Krupp that they sold most of the school's furniture to pay for the carnival, Krupp gets angry and they run away for their lives.

Chapter 6. The Invasion of the Incredibly Naughty Cafeteria Ladies from Outer Space. And the Subsequent Assault of the Equally Evil Lunchroom Zombie Nerds and the Deiirously Dangerous Death-Defing Dandelion of Doom

One dark, clear night in Piqua, Ohio, a flaming object was seen streaking across the quiet midnight sky. It shone brightly for a few seconds and then fizzled out just above Jerome Horwitz Elementary School without anyone giving it a second thought. The next day, everything seemed pretty normal, as none of the students or staff paid any attention to the roof or asked about the spaceship on top. Inside of the spaceship were three of the evilest, hideous, and merciless spacemen every to set foot on the roof of a small Midwestern elementary school, named Zorx, Klax, and Jennifer. Their mission is to take over planet Earth, which they discuss by infiltrating the school and turning the children and teachers into large, super-powered evil zombie nerds. Jennifer tells her two teammates to wait until it is narratively convenient for their plan to work, and in the meantime, they will watch their every move on their trinocloscope  Meanwhile, in science class early the same morning, George and Harold are imitating dog and cat noises with Mr. Fyde thinking there are actual animals in the room making the noises. The children assure him that they didn't hear anything, and George advises him to leave and go see a doctor. However, Mr. Fyde wants to start the day's big "volcano experiment", and all of the students groan. George and Harold then learn about the effects of mixing baking soda and vinegar together (the two ingredients don't mix and make a slimy sticky liquid before exploding). When Mr. Fyde continues to hear cat and dog noises, he leaves to go see a doctor. George and Harold decide to play a prank on the cafeteria ladies by giving them a recipe that involves mixing baking soda and vinegar. The recipe is disguised as a cupcake recipe, with instructions to make a set of cupcakes for Mr. Krupp's birthday. The next day, George and Harold tape the recipe/birthday card onto the entrance of the kitchen. When the lunch ladies find the two pieces of paper, they decide to surprise Mr. Krupp and make cupcakes for the entire school. Instead of mixing a small amount of baking soda and vinegar, they mix a large amount into the mix. This causes the school to get covered in the slimy green mixture. George and Harold are shocked that the prank didn't go as they expected. The lunch ladies get mad at Mr. Krupp and quit (because he can't punish George and Harold because there's no proof they did anything wrong). He said that it was not his birthday. Mr. Krupp wonders where he is going to find three new lunch ladies by tomorrow morning.

Zorx, Klax, and Jennifer, badly disguised as humans, come in and take the open lunch lady job. Mr. Krupp is happy that the problem is out of the way now. He then calls George and Harold via the intercom and tells them to come to his office. They do so and Mr. Krupp punishes the duo by forbidding them from having any cafeteria food even though he clearly knows he has no proof they were responsible for the disaster that happened the day before. He states George and Harold from now have to pack their own lunches and eat in his office so he could keep an eye on them.

The next day, George and Harold bring their lunches to Mr. Krupp's office for lunch as per what Mr. Krupp told them. After Mr. Krupp is disgusted by the food that George and Harold are eating, he leaves for some fresh air. George and Harold decide to go change the lunch menu while he is out. When they arrive at the sign, they see someone else has already altered the menu. They then see that the students and staff have been turned into Zombie Nerds. George and Harold then sneak into the kitchen and discover the cafeteria ladies are really aliens who have just fed Evil Zombie Nerd Milkshakes to the students and staff which is why almost everyone in the school has turned into a zombie nerd. George and Harold learn of the spacemen's plans to feed super evil rapid growth juice to the zombie nerds tomorrow to make them huge and evil, so that way it would be easier to conquer Earth. George and Harold steal the growth juice and try to get rid of it by pouring it out the window, but they unintentionally pour it on a dandelion.

When the boys prove to Mr. Krupp that the lunch ladies are aliens and that everyone has been turned into Zombie Nerds, however, Mr. Krupp laughs at them assuming they were lying. So he calls Edith Anthrope into his office and she comes as a Zombie Nerd and takes a huge bite of Mr. Krupp's walnut made desk. As he sees this happen he is in shock. George and Harold then take Mr. Krupp into the lunchroom but an alien disguised as a lunch lady sneaks behind and grabs Harold as he runs off accidentally pulling off the Alien's gloves. One of the aliens snaps his tentacle (a physical impossibility as noted by Harold) at them, George tries to get a cup of water to pour onto Mr. Krupp's head but it was too late. So Mr. Krupp becomes Captain Underpants due to the snap of the tentacle and dashes off running and right after that, the aliens block off the exit. George and Harold however defeat the aliens with a rolling pin and frying pan respectively. Captain Underpants returns, but he is too late as the aliens are already incapacitated. George and Harold ask where was he when they needed him. Captain Underpants reveals that he was at the shoe store ordering a cheeseburger. While they are arguing, the aliens order the zombie nerds to destroy Captain Underpants and his two friends. The trio get surrounded quickly, Captain Underpants demands the two boys to retreat to the Underwear Cave but they tell them there isn't anything like that around, so they escape by going on the school roof and into the alien spaceship.

Inside they find some Anti-Evil Zombie Nerd Juice, some Ultra Nasty Self-Destruct Juice, and some Extra Strength Super-Power Juice. The aliens however then suddenly come in and lock them in a cell, but luckily George and Harold hid the juice cartons they found behind their backs. Zorx starts the ship up so that the ship is hovering a few feet above the school. Klax then takes some Super Evil Rapid Growth Juice from the fridge so that the aliens can put the juice in the spray gun which will shower the juice over the zombie nerds. While laughing victoriously at their apparent victory, George and Harold swap the labels of the juice cartons and the signs of the spray gun and fuel tank, so the aliens pour self destruct juice into the fuel tank instead of rapid growth juice into the spray gun, which makes the spaceship explode.

Captain Underpants jumps off the spaceship with George and Harold, claiming that he can use toilet paper to swing onto the ground as he proclaimed that he did it in his last comic book George and Harold wrote earlier. Of course, the toilet paper breaks because it cannot support their weight, so the trio start falling to the ground fast, but Captain Underpants' cape then acts like a parachute, making them fall more slowly and gently to the ground. However, they, unfortunately, end up landing near the mutated dandelion, who then grabs Captain Underpants down with its teeth and knocks George and Harold onto the school roof. George and Harold give Captain Underpants some of the superpower juice to help him break free and defeat the dandelion. The juice gave him the ability of enhanced strength and flight the ability to fight.

After the dandelion is defeated, George wonders how to get the zombie nerds back to normal. Harold suggests using the anti-evil zombie nerd juice to fix the problem. George notes that he was hoping for something more dramatic, but as they are running out of pages they should do it. Mixing anti-evil zombie nerd juice with root beer and having all the zombies drink it, they turn everyone back to normal, but not before getting the Captain to dress back up like Mr. Krupp and pouring water on his head.

Something has changed about Mr. Krupp though because he drank the super-power juice, so now whenever he becomes Captain Underpants, he can fly and use other superpowers, thus making it harder for George and Harold to keep tabs on him (evident after a girl snaps her fingers in front of Mr. Krupp while she was listening to music). Instead of Harold and George looking out the window witnessing Captain Underpants running into the city. They are outside on his cape clinging on as he flies into the city instead.

Chapter 7. The Perilous Plot of Professor Poopypants

Professor Poopypants, a scientist from a country where everyone has a silly name, New Swissland, has just invented a shrinking machine, the Shrinky-Pig 2000 and an enlarging machine, the Goosy-Grow 4000. He goes to America so he can show these inventions to everyone and help the world by using his machines to shrink the world's garbage and increase the world's food supply.

Meanwhile, the kids in Jerome Horwitz Elementary School are going on a field trip to a pizza place (similar to Chuck E. Cheeses). While George and Harold are waiting to get on the bus, they decide to change the school sign, until Mr. Krupp catches them "red-handed" since he has been hiding in the bushes next to the sign and thinks their sign changing is rude and offensive. As the boys' punishment, they are banned from the field trip and have to spend the whole afternoon cleaning up the teachers' lounge. The teachers laugh at them. Harold becomes saddened they won't get any fun, however George claims they can still have fun and comes up with an idea involving a ladder, a bag of powdered paste and a box of styrofoam packing pellets.

The two boys start to create a prank as payback against the teachers. First, they tape the water nozzle of the sink, to make it on when the water runs, second they fill powder of paste on the wings of the ceiling fan. Finally, they fill the fridge with millions of foam pellets.

When the students finally come back and go home, the teachers except Mr. Fyde (who is on bus duty) spend their time taunting at George and Harold, saying that they missed a good field trip. Mr. Meaner says that he was going to bring back a pizza, but, he ate it on the bus. When the teachers finish taunting the boys, they go off to the teachers' lounge. When the teachers go into the lounge to relax, they fall into George and Harold's trap. The teachers end up looking like abominable snowmen (they are covered with foam pellets that are stuck to their bodies due to them being wet and covered in powdered paste) and they run, scream, and chase George and Harold down the hall with Mr. Fyde looking at the window.

The next day, their old science teacher, Morty Fyde quits because he thought he had cracked up. First, he says a toilet ate him. Then he says that later he started hearing dogs and cats in his classroom, then he imagined the school got flooded with sticky green goo, and finally, he saw the other teachers chase George and Harold down the hall as "abominable snowmen". Mr. Krupp says that can all be explained as George and Harold's doing, but Mr. Fyde also insists that he saw some fat bald man in his underwear fly out a window (obviously Captain Underpants) which makes Mr. Krupp realize he has gone crazy since he has no proof that is George and Harold's doing. As Mr. Fyde dances in joy, Mr. Krupp wonders where he is going to find a new science teacher on such short notice.

Meanwhile Professor Poopypants has been trying to demonstrate his new inventions to the world, but nobody takes him seriously due to laughing at his silly name. Eventually he begins running out of money to become a teacher at a school. He then goes to a New York coffee shop and after finding an ad, he decides to become an elementary school science teacher. During this time The boy who sees everything his mother can't is seen pouring salt into Professor Poopypants's coffee. He is convinced that the innocence and sweetness of children will let them pay attention to him, but they all laugh at his name instead after he declares what it is.

A week later, Professor Poopypants manages to get the children interested in science by building a machine called the Gerbil-Jogger 2000 that allows gerbils to jog alongside their masters. However, this interest is short-lived (thanks to George), as he reveals his middle name to be Pee-Pee, causing the children to start laughing again. Ms. Ribble reads the story of The Pied Piper from Hamelin. This inspires George and Harold to make a Captain Underpants comic book about the Professor inventing an army of gerbil joggers to destroy the world using a headphones on the gerbils to control them and everyone in the comic including Captain Underpants laughs at his name, which destroys the last of Professor Poopypants' credibility with the students and drives him crazy (after he found a copy of the comic in the hallway).

Using his enlarging machine, he makes the gerbil machine as large as a tall building and then gets inside. He then shrinks the school and holds them hostage. He then unveils his plan to force everyone in the world to change their names so everyone will have a silly name instead of a normal one, and anyone who refuses will be shrunk. Professor Poopypants does this first on Mr. Krupp. As a result, Mr. Krupp becomes Lumpy Pottybiscuits. All the children find this funny, until Professor Poopypants forces them to use the chart to change their names as well. This leaves the students and staff to be quite shocked and almost horrified at their new names.

As bad as the situation was getting, George and Harold (now Fluffy and Cheeseball) had no choice but to get Captain Underpants's help knowing that they would regret it. So they rushed to Lumpy Pottybuscuits's (Mr. Krupp) office where he is seen under his desk cowardly hiding in fear of Professor Poopypants. Fluffy snaps his fingers at him and he becomes Captain Underpants (now Buttercup Chickenfanny, but Captain Underpants refuses to change his name) to steal Professor Poopypants' enlarging machine, but unfortunately he gets caught and both him and the machine are shrunk in the process. The enlarging Machine makes its way to Fluffy and Cheeseball but Captain Underpants wasn't seen bringing it to them.

Which Captain Underpants's presences is unknown, Fluffy and Cheeseball try to enlarge the school back to normal size by getting onto the roof, but they get flicked off the school by the Professor as they are falling to their deaths. Cheeseball quickly makes a paper airplane that Fluffy enlarges. The plane flies into many threats, yet tiny Captain Underpants rescues them and they end up in an abandoned alley. Captain Underpants was also the one steering the plane out of danger they assumed.

Fluffy tries to enlarge Captain Underpants, but he accidentally enlarges Cheeseball's right hand in the process, however Captain Underpants does become visible, George zaps C.U. until he is the size of Professor Poopypants' gerbil machine. Captain Underpants then fights and defeats Professor Poopypants. Once Professor Poopypants is defeated, everyone gets their names back. The boys use the shrinking and enlarging machines to get themselves, the school and Captain Underpants back to normal size. Then Captain Underpants gets dressed back up like Mr. Krupp before being soaked with water by Harold who was playing with the hose, turning him back to his old nasty self again.

Before Professor Poopypants is then hauled off to jail. George then questions Professor Poopypants wouldn't it have been smarter to try changing his own name instead of forcing the rest of the world to change theirs. The surprised professor notes he never thought of that. As per George's advice, Professor Poopypants changes his name so no one will make fun of it anymore. Sadly, he chooses his grandfather's name (on his mother's side), Tippy Tinkletrousers, which Dr. Diaper and the inmates at jail facility make fun of him (including the guards).

Meanwhile while at the Treehouse in the backyard of their homes. Harold tells George that he learned something today. The moral of the story ("I think this is the first time one of our stories had a moral," notes George) is that it's not nice to make fun of people.

Chapter 8. The Wrath of the Wicked Wedgie Woman

One fine day, Ms. Ribble walks into George and Harold's classroom and announces she is planning on retiring at the end of the school year. She forces everyone to make happy retirement cards for her. The boys make a Captain Underpants versus Wedgie Womancomic book instead. In the comic book, Captain Underpants is stopped by spray starch, which makes his underwear stiff and uncomfortable, and so he loses his powers until he gets some fabric softener from some passing kids. When Ms. Ribble finds the comic George and Harold made, she becomes furious and sends them to the principal's office. George protests that all they did was use their imaginations, but Ms. Ribble reminds them that using their imagination is no longer allowed in this school.

Once inside the office with all their things, Ms. Anthrope, the school secretary, tells them that Mr. Krupp is on the phone and orders them to copy the "Friday Memo" for her and makes the boys run some errands by letting them pass out "Friday Memo" (a weekly newsletter that shows the events of the upcoming week) to the entire school while she goes out to lunch. George moans and Ms. Anthrope tells them to deal with it. Before that, they made their own Friday Memo by using Ms. Anthrope's computer (since it was still on) to change a few events. They begin handing out copies of this memo when Mr. Krupp sees them, but they are able to avoid any suspicions without saying that Ms. Anthrope told them to give out the memos. Harold then tricks Mr. Krupp into signing the card claiming they are going to give it to Ms. Ribble. Mr. Krupp sees nothing wrong there and writes "Signed Mr. Krupp" on the inside of the card.

Later on, when Mr. Krupp learns about them changing letters on the sign and their comic book that they made about Ms. Ribble, he puts them in detention. They defiantly say they won't give Ms. Ribble her card. Mr. Krupp steals the card and says he'll give it to her personally. The boys secretly smile at how effective their use of reverse psychology was.

Meanwhile, Ms. Ribble's retirement party gets off to a bad start and only gets worse. She makes the whole class sing a song about her and later eat chunky tofu ice cream (by which time it has melted as she was preoccupied screaming at the boys for singing out of tune). She then receives the cards that the children made for her and several are torn to pieces (Ms. Ribble asked the students to draw a butterfly on their cards; some of the students accidentally drew polka dots on their butterflies and one boy drew a smiling sun on his card, resulting in him having to stand in the corner). Mr. Krupp gives Ms. Ribble the card, which reads "Your one hot mama! on the front and inside it reads "Will you marry me? Signed, Mr. Krupp." The other teachers assume that Ms. Ribble agrees, and on Saturday, the wedding is to be held in the school auditorium. For the 5 days before the wedding, each day ends up with something weird going on on that day (On Monday, the students do not turn up because of a "lack of interest"; on Tuesday, they turn up in their pajamas and picking their noses; on Wednesday, the students wear expired egg sandwiches on their heads and mustaches drawn on their faces in permanent marker; on Thursday, the students engage in a food fight while the football team lay waste to the teacher's lounge; on Friday, the students turn up for their class photos dressed as bees). Mr. Krupp is too shocked by the whole wedding thing to admit the truth that he doesn't want to marry her. George and Harold insist that the wedding should be in their math test schedule, which is on Monday.

At the wedding, while the orchestra is playing music, the rabbi of the wedding approaches the duo and states he already heard about them and warns that he doesn't want them doing any pranks at the wedding. George and Harold have made it official to him they have no tricks planned (for once). On the altar, just before they get married, Ms. Ribble breaks up with Mr. Krupp, saying that despite liking all of his cruelty she couldn't marry him because he has a funny-looking nose (the joke is that the two of them have identical noses). Mr. Krupp is angry and says he never wanted to marry her anyway; it was just a trick of George and Harold's. Due to that, Miss Ribble totally goes berserk and ruins the wedding. Ribble tries to attack the boys, but they luckily escape when the cake splats on Ms. Ribble.

When school restarts, Ms. Ribble privately tells them that she has dropped their B's and C's to F's and G's (grade lower than an F; in Harold's opinion, there is no such thing as a G in the grading system; see below), so they will flunk the fourth grade now. George states that's not fair, but Ms. Ribble claims to get used to it as life isn't fair.

Later that afternoon, George says Ms. Ribble can't get away with what she did. He says they need to tell someone about this to justify this wrongdoing. Harold says nobody will believe them. George says there is something they can do as he starts looking through the drawers and finds the 3-D Hypno-Ring. A shocked Harold claims he thought they threw that away, but George says they only threw the instruction manual away, but he remembers how it works. They decide to use their 3-D Hypno-Ring to hypnotize Ms. Ribble into changing their grades back to normal. Harold reminds George they fooled around with it last time, but George notes this time they'll be serious about it this time.

The next day, George and Harold wait until the other kids have left for home at the end of the day The duo try to be safe about this when they hypnotize her, giving her instructions not to do anything weird like turn into Wedgie Woman and try to take over the world. Unfortunately, it turns out that the 3-D Hypno-Ring, when used on a woman, accidentally causes her to do the opposite of what she is hypnotized to do (as noted in a news message that interrupts the chapter for a brief moment). After believing they gave her everything they needed her to do, Harold snaps his fingers.

Ms. Ribble declares herself to be Wedgie Woman and attacks George and Harold in their clubhouse. Their container of super-power juice (from book 3) accidentally lands on her head, so she now has super-powered intelligence and hair. Her hair forms into several tiny hands, which can extend great distances, which is ideal for giving someone a wedgie and holding them hostage in midair.

Wedgie Woman kidnaps the boys and uses her super-powered intelligence to build robot copies of the two boys, Robo-George and The Harold 2000. George thinks the Extra Strength Super Power Juice must have soaked into her brain. The robots are equipped with Spray Starch to take away Captain Underpants' powers. They are then sent to Jerome Horwitz Elementary School.

The robots pose as George and Harold, except the two of them behave perfectly much to Mr. Krupp's dismay because he assumed the boys were faking good behavior as a prank on the teachers. During soccer practice, Harold 2000 kicks the ball through the page of the book and gets in trouble by Mr. Krupp but when Mr. Krupp snaps (literally) at Harold 2000, he turns himself into Captain Underpants. He thought that the Robots were the real George and Harold and asked them to help (he stated that he's surprised that they were larger and can fly). He is then defeated by the two robots and their spray starch. He falls from the sky before the robots hang him by the underwear onto a wooden pole. Meanwhile, George and Harold were watching the action on Wedgie Woman's TV (built with a fish tank and an electric toothbrush), and manage to escape from Wedgie Woman's deathtrap to find Captain Underpants.

The Wicked Wedgie Woman then gives wedgies to all the police officers in town and hangs them from traffic signs, aided by her two robots, which have expanded to gigantic size. The Chief calls for reinforcements, but Wedgie Woman's robots take care of them. George and Harold find Captain Underpants, who is convinced the spray starch took away his powers (it actually didn't) thanks to the placebo effect (mistakenly called the placenta effect by George and Harold) and needs fabric softener to get his powers back. George hears of a store nearby that just recently opened, but it turns out they sell anything butfabric softener, so the duo must come up with a new plan.

George and Harold make a comic book about how Captain Underpants is impervious to spray starch if he says, "I summon the power of Underpantyworld!” Captain Underpants reads the book, say the words, and regains his powers. He then defeats the two robots.

At the showdown between Captain Underpants and Wedgie Woman, Harold returns with the 3-D Hypno Ring. George returns with a large box. Harold asks what is he going to do that. George shouts to Harold that he's going to get rid of this box of extra-strength spray starch. Hearing this, Wedgie Woman steals all the bottles in the box and sprays them everywhere.

When the smoke clears, everyone is bald (except Captain Underpants, who was already bald). It turns out the box didn't contain extra-strength spray starch and that the box was actually full of hair remover. George reveals that he had used reverse psychology to get Wedgie Woman to use it. With her hair gone, Wedgie Woman can no longer harm anyone. Harold freaks out on his bald head, but George tells him to relax as their hair will grow back.

Captain Underpants is about to send Wedgie Woman to jail, but George and Harold tell him they can handle her. They then tell him to go put some clothes on and splash water on his face and Captain Underpants complies. The boys then hypnotize Ms. Ribble, and by using reverse reverse psychology (they tell her to do the opposite of everything they want her to do, like a double negative), they get her to lose her superpowers, forget everything that happened in the last few weeks, become the nicest teacher in the history of the school and bake fresh cookies for the class every day (If you look closely you can see that Ms. Ribble has a wig and that the boys are wearing backward baseball caps).

The next day, Ms. Ribble enters the classroom looking quite friendlier than usual. She tells the class that she has good news for them and the class cheers. However, when she tells them it's time for then has George and Harold teach the kids how to make their own comic books while she passes out cookies to the class. George and Harold note that since she is happier now, she will probably live longer. They also note how hypnosis is fun and helpful sometimes

Chapter 9. The Big Bad Battle of the Bionic Booger Boy

On demonstration speech day in Ms. Ribble's fourth grade English class, George Beardand Harold Hutchins show off a new prank of theirs, the Squishy. The idea is to place fold two ketchup packets in half and carefully place them under a toilet seat so the next person who sits on the toilets gets ketchup sprayed all over the back of their legs (or the front, if they push down the toilet seat while standing in front of it). They demonstrate by putting two ketchup packets under the lid of a large garbage can with a toilet seat taped to the top. George and Harold each grasp one side of the toilet seat and together push down, making the class thrilled (except for the two kids sitting directly in front of the toilet seat, who were sprayed with ketchup.)

All the fourth graders (including Ms. Ribble, who had become quite different since the last book) want to try it out, so they leave to the cafeteria to get some ketchup packs, but Melvin Sneedly, the bossy nerd from Book 2, forces blocks the classroom door and forces everyone to get back to their seats and watch his show and tell project since there are only 15 minutes left before lunch. He then shows off to the class a combining machine called the Combine-o-Tron 2000. Using his hamster, Sulu, and a robotic hamster body he built, Melvin uses his invention to combine the two elements so Sulu is now a bionic hamster and waves a metal detector around Sulu with the reading going off the chart. Melvin then wants to demonstrate his new powers to the class.

Since Sulu has special powers, Sulu no longer obeys Melvin. When Sulu does not respond to any of Melvin's commands, he later threatens to hit Sulu with a paddle if he doesn't demonstrates any of his new powers. Sulu unexpectedly grabs both the paddle and Melvin and then spanks Melvin continuously. Melvin starts wailing and blubbering though Sulu hadn't really spanked him, and calls him a "bad hamster" and tells Sulu that he never wants to see him again for as long as he lives. Melvin then runs out of the classroom crying and everyone (including their teacher Ms. Ribble, run behind chanting "Squishies!")George and Harold stay behind to comfort the forgotten hamster and assure him not to feel bad, as Melvin is a real meanie, and Harold asks him if he wants to come home with them and live up in their tree house. Sulu jumps onto George and Harold's shoulders and licks their faces. George officially adopts the bionic hamster and Harold tucks him into his shirt pocket. The three friends head off to the lunchroom.

Meanwhile, the school principal, Mr. Krupp, comes marching into the office in a particularly foul mood. He stops beside Miss Anthrope's desk, huffing and puffing, and asks for his coffee. Miss Anthrope responds "Get it yourself, tubby!" and Mr. Krupp tells her he doesn't need her lip today and demands his coffee right now. Edith instead asks for him to get her a cup, too, while he's at it. Mr. Krupp screams in frustration and grabs a newspaper, heading toward the faculty restroom. After getting pranked with a Squishy by Ms. Ribble, he storms out of the door and vows to get George and Harold, but Ms. Ribble laughs that she actually did it, and introduces the Squishy as the latest fad. Mr. Krupp, however, doesn't believe her, and searches for the two in the cafeteria. On the way he notices many other victims in the hallway that have fallen to the Squishy (mostly first, second, third, fifth, and sixth graders) complaining about ketchup stains on their lower clothing. Mr. Krupp then yells at George and Harold that he got ketchup in his underpants as well as half of the kids in the school. George and Harold protest they never did any of those pranks despite demonstrating it and some of the fourth graders support them. Unfortunately, Melvin does not agree with any of them and proudly tattles they taught the prank to the other fourth graders during demonstration speech day. Mr. Krupp then thanks him for the proof and points George and Harold to the detention room as punishment.

George and Harold are angry that Melvin is a big tattletale, so they decide to teach him a lesson and get even as well. During last period, Melvin becomes furious when George and Harold make a Captain Underpants comic book starring him as an evil mayor who creates a robotic jail who jails people for unusually minor refractions. Finally, when Melvin becomes the victim of a Squishy, he decides to get his revenge on the boys.

Melvin goes home and builds a robot that is larger than him and has various powerful abilities. His idea is to combine himself with the robot so he will have special powers like Sulu, that way he can get revenge on George and Harold and astound the female students, Ms. Ribble and Mr. Krupp. Unfortunately, Melvin sneezes at the last moment (this was due to him sneezing a few times due to being allergic to the family cat Danderellla), so he gets combined with the robot and boogers, turning him into the Bionic Booger Boy.

The next day, Melvin does not show up at school but the other do not mind. George and Harold have Sulu do a trick during show and tell day by using watermelon seeds to destroy a dead tree. The kids are so amazed that they start cheering and petting Sulu. Soon Melvin comes in as a disgusting bionic booger monster to the shock and disgust of his classmates and Ms. Ribble. He explains that he tried to combine himself with a robot the night before, but sneezed at the last second causing his boogers to combine with him too. Melvin explains he is already trying to build a Separatron 1000 to reverse the process, but it will take 6 months to finish due to the complexities of cellular separation. George suggests switching the Combine-O-Tron's batteries around to reverse the process, but Melvin calls that the dumbest idea he has ever heard of.

Melvin is very disgusting now, but not unhappy because there are some positive sides to being a bionic booger boy. He's now the star football player (no one wants to tackle him because he's covered in boogers) and ace volleyball server (no one wanted to hit it back due to the ball being covered in mucus). He even gets his own personal drinking fountain since nobody wants to use it after he globbered all over it. While most of the kids are jealous of this, George and Harold aren't as considering the many villains they faced previously, they are just glad Melvin hasn't become a villain who would want to destroy the world.

Cold and flu season comes, however, and Melvin begins to act differently, he starts sneezing a lot and when Ms. Ribble asks him to not forget to cover his mouth, it only made things worse due to the gooey mucus being spread everywhere when Melvin covers his mouth when he sneezed again. Ms. Ribble then says "On second thought Melvin, don't cover your mouth next time."

The next day, Ms Ribble for some reason is out sick with a cold. Mr. Krupp is put as a substitute, but is shocked to find almost everyone wearing raincoats and umbrellas. He demands an explanation for this before Melvin sneezes. Mr. Krupp returns a few moments later with fresh clothes, a raincoat and an umbrella. When Mr. Krupp tells them they are going on a field trip to Snoddy Bros. Tissue Factory, Melvin starts speaking like Frankenstein and declares out "Me no like tissues!", shocking all of the other students.

When the class visits the tissue factory, they take a tour though Melvin is the only one that is terrified. After the tour, Mr. Snoddy offers to give everyone tissue packs. Melvin refuses (he calls the tissues "bad magic"), but Mr. Snoddy assures him that everyone loves them and that these tissues can really help wiping out mucus. He then throws a couple onto Melvin, but this causes Melvin to become gigantic and evil as a natural defense against the tissues (as well as the Flexogromnic-steel in Melvin's endoskeleton). Melvin's growth and angers destroys the bulding and the various things surrounding the building and he kidnaps Miss Anthrope before storming out to the city..

George and Harold hid behind a window curtain at this time and later Mr. Krupp hid with them behind the curtain, As George explains that there is only one person who can save Mr. Ribble, must to Mr Krupp's dismaye as to who that person could be, George snaps Mr. Krupp into Captain Underpants to save the day. He saves his secretary, Edith Anthrope, from the Bionic Booger Boy, and she gives him some wet kisses as thanks. The water from the kisses unfortunately turns him back into Mr. Krupp and he gets caught by the Bionic Booger Boy when he demands an explanation from George and Harold, on why he is in his underwear. George and Harold try to get him to become Captain Underpants again through finger snapping, but due to Mr. Krupp's face still being covered by the slobbery kisses the snaps have no effect. Melvin swallows Mr. Krupp whole and then he goes for George and Harold.

Before Melvin can eat George and Harold, Sulu comes in to save the day and defeats Melvin. First Sulu hits Melvin on the head with a big cane. Then hits him in the belly with a big boxing glove. Finally, Sulu gets a pair of big teeth and snaps Melvin in the tushy. He then falls unconscious onto the ground with news people telling the story right next to his unconscious body. Melvin's parents, who are scientists, come in and pledge to try to help turn their son back to normal. By George's suggestion, they reverse the batteries in the Combine-o-Tron 2000 though it was only to prove to George that it will not work. The process somehow surprisingly works, and Melvin and Mr. Krupp are brought back, with the robotic booger globs flying off and landing on three building walls. They are unfortunately combined together for some reason, so Mr. Sneedly fires another blast and they are seemingly back to normal.

However, Mr. Krupp and Melvin start acting strange, with Mr. Krupp claiming credit for building the Combin-o-tron 2000, and saying, "You guys are so immature!" and Melvin giving punishments to George and Harold and claiming will punish them so badly that their kids will be born with detentions. He also says to George and Harold "In my office, PRONTO!" The robotic booger globs then come to life and one of them then destroys the Combine-o-Tron 2000, causing Melvin's parents to flee for their lives. The three Robo-Boogers then chase Melvin, Mr. Krupp, George, Harold, and Sulu

Chapter 10. The Revenge of the Ridicioulus Robo-Boogers

The three Robo-Boogers, Carl, Trixie and Frankenbooger, chase our heroes through town until they are cornered in an alley. They are about to destroy the four heroes when Sulu swallows them and then spits them into outer space. As everyone prepares to go home, it becomes obvious that there was a mistake with the Combine-o-Tron 2000, and now Melvin and Mr. Krupp have switched bodies. Several jokes are made with this outline, including "Kruppy the Kid" (Mr. Krupp in Melvin's body) roars and Ms. Anthrope to give him coffee or he would fire her. Seeing only a fourth grader, Ms. Anthrope gives him a wedgie. As for "Mr. Melvin" (Melvin in Mr. Krupp's body), he is also the basis of some abuse as he runs to hug his mother, who only sees a guy in his underwear coming to give her a hug, and promptly and ruthlessly assaults him with her purse.

After these incidents, George and Harold discover the mix up and explain it to Mr. Melvin and Kruppy the Kid. Mr. Melvin notes he could solve this problem right away if he still had his Combine-O-Tron 2000, but the Robo-Boogers smashed it in the last book. Understanding they'll need to use that invention to get everything back to normal, Kruppy the Kid orders Mr. Melvin to build a new Combine-O-Tron, but Mr Melvin says that will take six months. Kruppy yells at Mr. Melvin he has got a school to run. Mr. Melvin apologizes and says building a cellular combiner is extremely difficult. It is not easy like building something like a robot, a time machine, or a PATSY. George suggests making a time machine to get the Combine-o-Tron back. Struck with what was originally George's idea, Mr. Melvin snaps his fingers. But oddly, Kruppy the Kid becomes Captain Underpants, his alter ego and the superpowers somehow following Mr. Krupp into Melvin.

When "Kruppy the Kid" (in Melvin's body) turns into Captain Underpants, George and Harold are forced to tell the secret of Captain Underpants to "Mr. Melvin", who was utterly fooled by this because Captain Underpants is bald and Mr. Krupp has hair (it's strange that the kid with perfect grades couldn't see through Mr. Krupp's bad toupee). They guess that the reconfigured Combine-O-Tron must have somehow transferred the super powers to Melvin's body when it blasted Mr. Krupp and Melvin a second time. Mr. Melvin, after finding out, declares to George and Harold once he gets his Combine-O-Tron back and reconfigure it, he is going to keep the superpowers in his body to make himself a superhero. He then threatens George and Harold to make a comic about him defeating Captain Underpants and becoming the world's best superhero (he also tells them to give him a cool name and to not make him look stupid), or else he will make the teachers give them 12 extra hours of homework for the rest of their lives.

Since it would take a long time to make a new Combine-O-Tron, Mr. Melvin decides to build a time machine, which is built in one day. He builds it in the school library, which is run by Miss Singerbrains, a biblioclast (book hater) (this is a response to the banning all of the books). The idea is that no one goes to the library because it only has one book in it. After getting a portable potty from the basement, Mr. Melvin tells Ms. Singerbrains she is fired for the rest of her life.

Later after finishing the time machine and getting George and Harold into the library, Mr. Melvin explains to George and Harold that they must be careful with the time machine, because if it's used two days in a row (the machine needs to cool off every other day it's used), some unknown bad thing will happen (an oppozo dimensional reality rift will open up if this occurred). He tells them to use the Forget-chama-call-it 2000 on anyone that sees them on their journey, so that way nothing bad will happen to the delicate timeline and change the future. George and Harold go back in time two days and retrieve the Combine-o-Tron after it gets Melvin and Mr. Krupp back to normal, but before it is smashed (they replace it with a look-alike). This is done thanks to the use of the Forget-chama-call-it on Melvin's parents.

They go back to the time machine in the library, where Miss Singerbrains steals the Combine-o-tron and the Forget-chama-call-it and drives off to the police station. The boys go back in time and adopt a Quetzalcoatlus and name her, "Crackers", then go back to the moment when Miss Singerbrains stole their stuff, then get their machines back thanks to Crackers. Miss Singerbrains is convinced she is dreaming because pterosaurs don't exist at this time. Harold goes to return Crackers back to her own time period, then they erase Miss Singerbrains's memory and go back to their own time.

Meanwhile, Kruppy the Kid, as Captain Underpants, has been getting into trouble by doing stuff like preventing the school football team from winning an important game by stealing the ball, which he mistakes for a UFO (the opposing team then tackled him which caused the home team to lose). Kruppy the Kid also destroys the skateboards of three skateboaders since they refused to go away from a no skateboarding area. He then spanked them as punishment for everyone. Kruppy the Kid then tries to rescue a cat from a tree. This backfires as Kruppy the Kid leaves two ladies he was trying to help across the street in the tree. The football team, the skaters, and the old ladies are now mad at Kruppy the Kid. Mr. Melvin gets Captain Underpants to come to them. He uses the Combine-o-Tron to switch them, so Melvin and Mr. Krupp are back in their own bodies, but Melvin sneakily gives himself Captain Underpants's superpowers.

Meanwhile, in space, Carl, Trixie, and Frankenbooger grab onto a spaceship that was examining Uranus, where the robot and the toilets from Book 2 are. They hang onto the spaceship as the spaceship goes back to Earth. Once on Earth, they start destroying the spaceship center.

Captain Underpants, despite the fact that he doesn't have super-powers, decides to go after the Robo-Boogers. George and Harold follow him. They originally lose to the Robo-Boogers, but figure out that the robo-boogers die when they come into contact with oranges (the vitamin C in the oranges counteracts against the cold and flu viruses that made the boogers evil). This way, they beat Carl, but Trixie and Frankenbooger become more cautious and dodge the oranges.

Captain Underpants defeats the Robo-Boogers by standing on top of John's House of Toilets (the top of the store is a giant toilet lid) and doing an annoying dance. The Robo-Boogers start to climb up the building, when they get hit by a well-placed Squishy

Chapter 11  Stopped Big Melvin

Soon George and Harold have to answer questions for the Eyewitness News crew, but Melvin comes and lies to the Eyewitness News crew, saying he beat the Robo-Boogers with his super-powers. While Melvin tries to make Captain Underpants bow down to him, George and Harold sneak back to the school. George and Harold then return with the Combine-o-Tron 2000 & Forgetchamacallit-2000. They then use the Combine-O-Tron on Melvin and Captain Underpants, giving Captain Underpants his super powers again. They then erase the memories of the news crew and the TV audience with the Forgetchamacallit-2000.

Melvin wails about how he's not a superhero anymore, but everyone doesn't care because he was a selfish jerk for the past TwoBooks. George states to Melvin he should just be happy he didn't get his comeuppance, however Melvin does get his comeuppance when the people Mr. Krupp and Captain Underpants bugged while they were in Melvin's body (Miss Anthrope, the football team, 2 old ladies, and 3 skateboarders) come back for revenge on him. They then chase him down into the sunset. As George and Harold leave back to their treehouse, they use a water fountain to splash water on Captain Underpants' face and return him to his Kruppy old self (without getting to get dressed).

When George and Harold return to their clubhouse, George learns that Harold did not take Crackers back to the dinosaur age, but is keeping her as a pet, like Sulu. Harold asks if they can keep her tonight. George agrees, but they take her back tomorrow

Chapter 12. The Preposterous Plight of the Purple Potty People

The next day, George, Harold, Sulu and Crackers go into the time machine to send Crackers back home, even though Melvin said something about not using the time machine two days in a row. Harold is hesitant on using it and says that they should let it cool off today, but George assures Harold that nothing bad will happen if they use it two days in a row. George Beard, Harold Hutchins, Sulu, and Crackers have now ended up in an alternate universe where the whole world is the opposite of their normal world (instead of being perched up in a tree in the Cretaceous Period of the Mesozoic Era) as Melvin warned them about in the last book. Good is bad, smart is dumb, and heroes are villains. For example, Melvin Sneedly is struggling to comprehend a simple children's book and Mr. Krupp is nice and has a sense of humor (like Captain Underpants does). After they realize these events taking place and then some, there they see evil versions of George and Harold (George and Harold's evil counterparts) and they learn through one of their evil twins' comics that they had turned their principal into an evil supervillain named Captain Blunderpants. Sulu and Crackers are kidnapped by Evil George and Evil Harold. They are hypnotized to be evil. Sulu becomes evil and attacks Good George and Good Harold but Crackers, on the other hand, saves them (which Good George and Good Harold can't understand why).

The heroes finally get back to their normal dimension of the multiverse but end up unintentionally bringing Nice Mr. Krupp, Sulu, and Evil George and Evil Harold with them. Evil George and Evil Harold transform Nice Mr. Krupp into Captain Blunderpants by getting water on his head and the 4 began to raise havoc into the town of Piqua. Good George and Good Harold take the 3D Hypno Ring so that they could dehypnotize Sulu and the Extra-Strength Super Power Juice just in case. However, Mr. Beard stops Good George and Good Harold from leaving the house and forces them to come inside as it is Grandparent's Day and Good George and Good Harold have to eat dinner with their grandparents at Good George's house. While Good George and Good Harold try to explain to Mr. Beard they need to leave, George and Harold's grandparents take the remainder of the Extra-Strength Super Power Juice and drink it.

Elsewhere, Evil George and Evil Harold find Good George and Good Harold's treehouse, rummage through their personal belongings and find the "Goosy-Grow 4000". They then use it to transform Sulu into a giant monster. Sulu charges at Good George and Good Harold But Crackers flies in and Good George and Good Harold flee from their home flying over on Crackers' back to be Chased by Evil Harold, Evil George, and Captain Blunderpants. The Good George and Harold decide that they have to drink the superpower juice to fight back, but unfortunately, they realize it is somehow empty despite there being a third amount of juice earlier. Since there was no more of the Super Power Juice left, Good George explains that there is only one plan left they can resort to now.

The duo and Crackers managed to escape the evil duo that was following them, They go to Nasty Mr. Krupp's house (which Good George and Good Harold covered in toilet paper at an earlier point) and knock on his door. Right after Nasty Mr. Krupp answers, Good George and Good Harold quickly snap their fingers to turn Nasty Mr. Krupp into Captain Underpants. The latter then defeats the "Giant-Evil Sulu,"also known as "Hamsterzilla". The evil trio notice this after robbing a bank, so Captain Underpants now must fight his evil counterpart, Captain Blunderpants. However before the epic battle begins, Captain Blunderpants is transformed back into Nice Mr. Krupp by the snap of Good George's finger. The duo reveals that they didn't forget about reading their evil counterparts' comic book on how Blunderpants and Nice Mr. Krupp can switch identities.

Captain Underpants ties the alternate counterparts up, but when Good Harold states that nothing can go wrong, the worst thing is that something can go wrong, this causes a rainstorm to turn Nice Mr. Krupp back into Captain Blunderpants and Captain Underpants is turned back into Nasty Mr. Krupp. Good George and Good Harold try snapping their fingers, but the snaps have no effect on either Nasty Mr. Krupp or Captain Blunderpants as the rain is pouring too hard on them. Nasty Mr. Krupp can't figure out how he got outside, so he goes back to his soggy toilet paper covered home to get back to bed not contributing to the plot of what is happening around him.

With Captain Underpants out of commission, Good George and Good Harold are forced to get away on Crackers while Captain Blunderpants flies after them with Evil George and Evil Harold in his hand. Good George soon finds the Shrinky Pig 2000 in the treehouse which the gang can use to make the evil twin counterparts no longer a threat. Unfortunately, it is too late as Captain Blunderpants grabs the duo by their shirts while the device falls into the hands of Evil George and Evil Harold. When all seemed lost at a point before Captain Blunderpants can finish off Good George and Good Harold due to Captain Underpants not being in commission to save them, someone's voice stops him from doing so.

George and Harold's grandparents have arrived and order Captain Blunderpants to put down their grandchildren, but he just tightens his grip on them, so George and Harold's grandparents become Great-Granny Girdle and Boxer Boy. They then place two curtains on them as capes before they defeat Captain Blunderpants and save their grandchildren. Good George notes he figured out what happened to the Super Power Juice that disappeared earlier.

However, Evil George and Evil Harold are prepared to use the Shrinky-Pig 2000 on their alternate twins, but Good Harold claims they can go right ahead as they are holding the device backward. The evil twins stupidly believe this and turn the device around before activating it, resulting in themselves being shrunk. After giving the evil twins the punishment they deserve and George and Harold's grandparents fly off for a romantic dinner, the duo dehypnotizes and shrink Sulu to normal. They then take Evil George, Evil Harold, and Captain Blunderpants back into the Purple Potty, and then they kick them back to their universe.

Good Harold states everything worked out perfectly, but this causes policemen to arrest them because they think they are the evil George and Harold, who robbed a bank while Captain Underpants was fighting Sulu, also known as Hamsterzilla. Good Harold again states that things cannot get any worse because they are going to jail for the rest of their lives

Chapter 13. The Terrifying Return of Tippy Tinkletrousers

As George and Harold are being taken away by the cops, the cops stop by Mr. Krupp's house where he is seen taking out the trash after cleaning the house from the wet soggy toilet paper, The Cops rush and handcuff a confused Mr. Krupp. After their court date, George, Harold, and Mr. Krupp aka Captain Underpants were arrested and were sent to jail. George and Harold are sent to the Juvenile Hall while Mr. Krupp was sent to the Piqua State Penitentiary. The 3 were actually framed and mistaken for Evil George Beard, Evil Harold Hutchins, and Captain Blunderpants's evil antics causing chaos in the town of Piqua.

One autumn afternoon, Tippy (who is also a prisoner from the fourth book) is tasked to build a statue of Warden Gordon Bordon Shmorden who is the chief jailer of the prison, Tippy does the task but instead builds "a giant robot suit". Krupp notices Tippy and he remembers and confronts him for what happened the last time when he shrunk the school and make everyone change their names. However, Krupp does not remember that he as Captain Underpants was the one to put a stop to Tippy's reign of terror that day.

On the day Tippy presents his robot suit to Gordon Shmorden, he reveals his work and climbs on to the suit and freezes everyone in his way (the same suit used at the very end of the eighth book). Tippy then grabs Mr. Krupp and forces him to spill the information of Captain Underpants and to give him the information of George and Harold whereabouts. Tippy soon finds George and Harold and puts Mr. Krupp down, wanting information of Captain Underpants. Krupp picks on them telling them they were in a lot of trouble. Seeing that they were in danger of Tippy plotting his revenge, George and Harold act fast and snap their fingers at Mr. Krupp who turns into Captain Underpants. Tippy then realizes that Mr. Krupp was Captain Underpants all along and Captain Underpants gets chased, while Tippy is unsuccessfully trying to freeze him, soon he accidentally freezes his robotic legs and as a last resort, time travels to five years into the past. Captain Underpants flies down in confusion wondering where he might have gone.

Chapter 14. The Bully Battle The story switches to George and Harold as kindergartners who have a hard school life due to Kipper. (a school bully and Mr. Krupp's nephew.) Harold's father had recently gotten divorced and moved to Nevada about six months ago, none of which had been easy for Harold. He didn't talk much about the subject, and kept to himself, mostly, and drew lots and lots of pictures, mainly about monsters and superheroes. The monsters he created were always evil and ferocious, and his superheroes were always brave and trustworthy. Harold loved getting lost in his wonderful hand-drawn adventures, where the heroes were always triumphant and gave the bad guys the punishment that they deserved.

Everyday, Harold would get dressed and eat breakfast, trying hard not to think about the tough day ahead of him. He hated every minute at his elementary school, with his mean teacher, rough bullies, and a straight-up evil principal. He would brush his teeth and very carefully place his favorite drawings into his backpack, unaware that this day, his life would be changed forever.

On that day, Harold's mother helped him put on his backpack at the front door, assuring him that he might make a friend that day. She then tells Harold that a little boy had moved in next door last weekend, and asks him if he knows his name. Harold had seen the kid once or twice but never met him clearly, and shrugs. His mom suggests that he should go over and introduce himself, but poor Harold shrugs again. His mother then sends him off with a kiss and hug and hands him two dollars from her purse for his lunch, but tells him not to use it on any of the vending machines. Unfortunately, Harold's lunch money would never reach the candy or pop machine anyways, as it was usually taken by a sixth-grade bully named Kipper Krupp, who, coincidentally, was the nephew of the principal. Kipper Krupp is Benjamin Krupp's 6th grade nephew and captain of the wrist wasting practice Kipper and his friends Bugg, Loogie, and Finkstein liked to bully the kindergarteners, Since Kipper was the nephew of Benjamin Krupp and he often called for his uncle when he's in a jam, nobody could figure a way to give him and his friends a lasting form of punishment. Mr. Krupp would readily punish anyone who was "bullying" his nephew: Kipper Krupp. Kipper just needed to yell out for his uncle and explain to him what happened, though he usually made it look like he was bullied in front of his uncle. For example, when Kipper punched a little girl in the stomach, Kipper told his uncle that the girl's stomach somehow hit his fist first. Benjamin always believed his nephew's claims no matter how illogical they seemed. Harold knew from experience that the wisest thing to do would be to stay out of Kipper's way, making his daily walk to school much more complicated. He quickly ran in spurts from trash can to mailbox to the tree, hiding behind any object he could find, just in case Kipper and his mooks were nearby.

Usually, the worst section of Harold's mad dash to school was the intersection by Dogwood Drive and Rosita Lane, due to no hiding locations except for the alleys then to the coffeeshop's tree and the sign at the gas station across the street. Most days, he was lucky when waiting for the walk signal, until this particular day.

Harold crouched quietly behind the tree at the coffee shop, concentrating on the traffic lights and cars, watching out for Kipper and his mooks. This was very stressful, but after a few minutes, the cars paused, the walk signal lit up, and Harold glanced left and right one more time before bolting for the display sign at the front of the gas station. Unfortunately, Harold was almost immediately noticed by the sadistic owner of the gas station, Billy Bill, who yelled at him to get away from his sign. Then, the bullies came and started beating up Harold while Billy Bill laughed at him.

Described as a "precocious" child, George's mother had already taught him how to read and write, and by kindergarten, scored higher on tests "than most children half his age." In fact, George was so smart for his age his teachers recommended he skip to the third grade, but his parents decided against it, reasoning that George would be overall better off in a classroom with students his age. George's parents, however, came to question that decision, as although it helped George develop adept social skills and was well-liked by his classmates, he was often bored in class due to his higher intellect and sometimes got into mischief, to the dismay of his teachers and parents.

When not riding his skateboard, reading comic books and graphic novels, or watching monster movies, George would often write stories, and had reportedly "filled up" twenty one spiral notebooks full of "marvelously silly adventure stories" he had written, one such being The Fart That Ate Detroit. Most of George's stories would often get him in trouble, due to at least most of them being filled with inappropriate and violent content for his age, despite his classmates enjoying them whenever he read them aloud.

Sometime during or before kindergarten, he and his parents moved from Michigan to Piqua, Ohio, in the hopes of starting a new life. On his first school day there, George's mother wanted George to make a good first impression at school by wearing a tie, which, after a short argument, reluctantly agreed to wear it, stating that "ties are for nerds". On the way skateboarding g h to school, George was waiting for the traffic light to change when he saw Billy Bill, an unfriendly and cold gas station owner, push his new neighbor, Harold Hutchins towards a few mean-looking sixth-graders, who yank the kid up and steal Harold's lunch money, while the gas station owner watched and cruelly told the kid he needed to learn to stick up for himself, apparently humored by the child's lack of advantage against the bullies. George was visibly angered by the hostility and unfairness of the circumstance, as the bullies and Bill were easily bigger and stronger than Harold and outnumbered him 5 - 1. When the light changed and the bullies had dragged poor Harold away, George walked over and switched the words on the gas station sign from "Free Brake Inspection" to "Free Bra Inspection", attracting the attention of an increasing mob of women, who became angry at the new words on the sign and beat the horrible gas station owner senseless. George parroted the same words Bill had said to the kid.

Finished with Bill, George skateboarded to the school and yelled at the boys to leave Harold alone. When the bullies Kipper Krupp and his gang began to run toward George, he undid his tie and proceeded to whip Kipper and his friends with his tie, scaring them to retreat into a trash bin. With the bullies in the trash bin, George stated firmly to them that if they messed with him or Harold again, they "will get the tie", and snapped his tie in the air again to make his point. Through his tears, Kipper wailed for his uncle Benjamin Krupp, who came over and demanded what was going on. Kipper framed George for bullying him, and took George and Harold (whom Krupp thought was lying about George merely defending himself) into detention.

In detention, the two sat quietly until the kid started to draw. Harold introduced himself as George's neighbor, and lent him papers to write on. George and Harold spent the entirety of the detention (which lasted all day due to Krupp being so busy that day he forgot about the boys) working on their first comic together, The Adventures of Dog Man. On the way out the school, the two came across Kipper and his gang, about to give "killer wedgies" to a couple of kindergartners, but when they saw George, the bullies released the kids and ran away. On the way home, the two talked about each other's interests and decided to start their own comic book company, Tree House Comix Inc.. After greeting his father, introducing him to Harold, making a couple of peanut butter and gummy-worm sandwiches, the boys went straight to George's bedroom and began writing a list of Kipper Krupp's strengths and weaknesses, only having but only needing "kinda dumb" under the weaknesses section.

The next day at school, the boys spent every free moment they had spying on Kipper and his gang, studying his schedule, behavior, and activities. They got his locker number and the type of padlock he used, even going so far as to stay after school, when Kipper had wrestling class. In just a week, George and Harold knew Kipper's schedule better than Kipper himself knew. One day after school, the boys went to a local hardware store and bought a padlock that was the same type as Kipper's, and went across the street to a toy store and bought a Susie Sunshine Friendship Bracelet Kit. That weekend, George and Harold spent most of their time planning and designing pranks to assist them in putting an end to Kipper's bullying. They got a roll of shelf-lining paper from the Beard family's kitchen and pants and dress shoes Harold's father left behind and nailed them to a pair of wooden stilts they had built.

On Monday when Kipper and his gang go to wrestling practice, George and Harold empty his stolen lunch money and uses it to buy pizzas for the kindergartners from Piqua Pizza Palace and puts money, coupons, instructions, and a tip for the delivery guy in the mail slot, and replaces the money with girly things like friendship bracelets. The next day they put dresses, and on the third day, dolls, while sending strange texts to Kipper's goons on all Three days getting all while placing a note from "Wedgie Magee" with it. causing him to get embarrassed in front of his friends.

However, Kipper eventually catches on to George and Harold's padlock, and replaces it with a Supa Doopa Combo Lock 2000 while wedging Donny Shoemeyer, and, the next day, him and his gang steal the pizzas that George and Harold bought for the kindergartners as a way to torture them even further. Infuriated, the two friends come up with another major prank on the bullies in retaliation. First, they fill the four bullies' lockers with shaving cream to pass it off as ectoplasmic ghost juice. Then they run outside scaring their heads off, while the cheerleaders were finishing their practice. Then they go to Kipper, Bugg, Loogie, and Finkstein's lockers and run for their lives when they see the ectoplasm.

While initially this works, Principal Krupp points out that the "ectoplasm" was obviously sprayed through the vents on doors and is shaving cream. Enraged and tired of the anonymous pranks, Kipper and his friends begin to torture the kindergarteners for answers, even stealing more pizzas, which George and Harold were actually counting on them to steal, as they ordered them to have double ghost chili peppers (Piqua Pizza Palace's hottest chili peppers) which cause the bullies' tongues to burn up completely, resulting in them getting sent to the nurse's office.

George and Harold eventually create a comic that tells the tale of Wedgie Magee and the signs of his curse that looks very old, all of which match their pranks and but ertxe hot chesse in thier man stik deiont so their burn they armpits. Then they take a couple of garden spiders and blow them into the vents of the bullies' lockers. Loogie, who has a fear to spiders, tell Kipper and the gang that they to get out of here.

Mr. Krupp was a in metting he the sarcming and goes to get to the bottom of this Kipper and his goons run to get into the restroom. After Kipper and his gang "see" that ghost (George on stilts, wearing a giant pair of pants), they run outside in terror, during a severe thunderstorm and power outage while beating Mr. Krupp.

On Monday morning, Kipper gives a 5 dollar bill to Donny and promises to return all the money he stole from him. Elsewhere, Kipper's friends are passing out money to the kindergartners and doing good deeds for them. Kipper and his friends eventually gave back all the money they stole and never picked on anyone ever again. George and Harold would later call off the vengeful wrath of Wedgie Magee after they were certain their enemies were truly reformed. However, it is revealed that what happened was what was supposed to happen is not what actually did happen. As it turns out, Tippy had time-traveled to when Kipper and his friends were running out of the school.

It then goes back to when Kipper and his friends were running out of the school. At this point, Tippy and his Robo-pants appear. Due to Tippy's dialogue with, Kipper and his friends while it was still dark, they mistakenly thought that it's the haunted pants of Wedgie Magee and become insane. Tippy then travels four years into the future when George and Harold were about to be arrested in Book 8. Unbeknownst to Tippy, his actions led to Kipper and his friends being sent to a mental health institute and the police to immediately suspect Mr. Krupp for what happened to the sixth graders (in both the original and changed timeline, Mr. Krupp was unintentionally beaten up by his own nephew, and his friends while escaping from the school due to a blackout). The Cops show up and blame Mr. Krupp. This eventually led to Mr. Krupp being fired which means in a few years he would not be hypnotized by the 3D Hypno Ring into becoming Captain Underpants.

Chapter 15. Undoing the mistake

Tippy then time travels back to the present time, thinking that kids five years from the past were weird. However, as Mr. Krupp was hypnotized when George and Harold were in the 4th grade, a universe is created where Captain Underpants never existed. Tippy arrives at a present destroyed and overrun by giant evil zombie nerds. After learning of the changes that have happened in the present, Tippy realizes the terrible mistake he made and becomes determined to return time to normal and save Captain Underpants. But Tippy immediately gets squashed by George and Harold, who are now giant zombies nerds. However, Tippy escapes at the last moment by placing a extra large novelty ketchup catsup packet under Zombie Nerd Harold. He then travels four years ago and freezes Kipper, Bugg, Finkstein, and Loogie who were running out the school going crazy from the young George and young Harold's first successful prank. Tippy freezes them from running further before his Tippy's Slightly Younger version arrives to accidentally scare them. When Slightly Younger Tippy does arrive, Future Tippy tells him that he is there to stop him from scaring the bullies. Then, he shrinks Slightly Younger Tippy and travels four years into the future. The bullies unfreeze and continue running as they were.

Chapter 16. The Revolting Revenge of the Radioactive Robo Boxers

Arriving in the present, Tippy sees that the timeline is back to normal, however he has also arrived at the point where George and Harold were getting arrested in Book 8. He then freezes the cops, and chases George, Harold, Crackers, and Sulu around town. The next day, George and Harold are still hiding from Tippy's robotic freezing pants.

They then go to to to the school with a plan to save the two pets by traveling 65 million years ago and leaving them there. However, Mr. Krupp then notices them and gets mad and furious that the two are running away from him while he is asking them to tell him why they are late to school. It then turns out that he is there with a box of curtains, because they keep on disappearing (due to his alter ego Captain Underpants using them as capes). When George and Harold reach the library, they lock the door behind them, so Mr. Krupp won't get in. However, Mr. Krupp begins to unlock the door with his keys and barges in after George and Harold who couldn't handle any more problems especially Mr Krupp, they really didn't have the time for him. He then barges in and bangs on the Purple Potty Time Machine demanding that they come out. However, then, Tippy then appears again, and is about to freeze Mr. Krupp. However, when they go back in time, Mr. Krupp also goes with them. (As, he was standing too close to the Purple Potty.) Tippy then sends Tiny Tippy back in time when George and Harold were going in the Purple Potty and Mr. Krupp soon follows. Tiny Tippy then learns that they're going to the Mesozoic era. He then tells his two selves the news, and the three Tippys go back 65 million years.

Meanwhile, 65 million years ago, George and Harold notice that Mr. Krupp is also there with them hanging on a tree branch calling for help. Harold goes out to grab his hand, but then Tippy kicks the tree. The five are then knocked down and the Purple Potty is then destroyed. George, Harold, and Mr. Krupp are saved by Crackers and Sulu. However, Mr. Krupp does not know this yet. Then, Tippy threatens to kill George and Harold. So the boys quickly snap their fingers at Mr. Krupp, turning him into Captain Underpants.

As Tippy chases the five, Tiny Tippy and Slightly Younger Tiny Tippy TinkletrousersTiny Tippy become tired of letting regular Tippy boss them around, so they go back in time to chapter 8 of book 9 to get the Goosy-Grow 4000 from the top half of their suit so that way they can grow bigger than big Tippy. Slightly Younger Tiny Tippy then zaps Tiny Tippy and turns him into Supa-Mega Tippy TinkletrousersThen, Supa Mega Tippy betrays Slightly Younger Tiny Tippy, who climbs onto his suit as a stowaway. He then goes back 65 million years ago when Big Tippy captures Captain Underpants, who up until then thought that they were playing chase.

Big Tippy then falls into a lake, turning Captain Underpants back into Mr. Krupp. Just then, Supa Mega Tippy and Slightly Younger Tiny Tippy arrive. Tippy then tells the two that Captain Underpants' weakness is water. However then, Supa Mega Tippy then tells Big Tippy that HE is going to destroy Captain Underpants, not him. Out of anger, Big Tippy sets off his nuclear bomb. But Supa Mega Tippy kicks him into another part of the world. However, the bomb still blows up, killing the all the dinosaurs. The six then travel to a time about 200,000 years ago, when cavemen first existed.

Supa Mega Tippy then captures George, Harold, Crackers, and Sulu. Sulu then tears a hole through Tippy's robotic hands, and the four friends fly off, promising Mr. Krupp that they'll come back for him. Tippy then holds Mr. Krupp hostage under a waterfall until further notice.

Meanwhile, the four friends travel over to a cavepeople village, asking for help. However, they don't understand their accent. Tippy then attacks the village, forcing them all to seek refuge in a cave. George and Harold discover that the cavepeople understand pictures better, so they write a wordless comic book on the cavewalls to help the cavepeople that Tippy is evil and he must be stopped.

After the cavepeople finish reading the comic, they and the duo all start drawing out plans on how to stop Tippy. They then set up traps for Tippy and even burn up his robot pants. And when he fires the Freezy-Beam 4000 at the cavemen, Slightly Younger Tiny Tippy tampers with it so it won't turn off. Tippy tries his hardest to turn it off, but the emergency shut off is stuck. The ice spreads throughout the destroyed village quick, and into the mountains. Slightly Younger Tiny Tippy then steals the Goosy-Grow 4000, and zaps himself to a range of 120-150 feet. As he is about to reach 200 feet, the Goosy-Grow 4000 then falls on the ice, spreading it throughout the world.

George, Harold, Crackers, Sulu, and the cavemen run over to Mr. Krupp to free him. However, the ice encases over everyone and freezes them. When all hope seems lost, Tippy, now 200 feet tall, grabs everyone with his robotic hands. Then, George and Harold snap their fingers again, turning Mr. Krupp back into Captain Underpants. Captain Underpants rips off Tippy's robotic pants, leaving him standing there in his boxers.

Using the pants as a net, Captain Underpants, George, Harold, Crackers, and Sulu take to cave people over to France, giving them a new place to live. When they return to Tippy, asking for a ride back to the future, Tippy squirts water from the water bottle at Captain Underpants' face, turning him back into Mr. Krupp. While they are all falling, Crackers is getting sicker and sicker for some strange reason. Tippy then captures the five with his hand, and they all get ready to go back home. George and Harold both vow to start acting more mature and take their classes seriously as they go forward in time.

About 200,000 years later, the five notice that they're home. As they are celebrating, they notice that everything looks so old. Then Tippy tells them that he will not hurt them, but is going to destroy Captain Underpants, and that's why he brought them thirty years after the present, so that way the world doesn't have to get destroyed when Captain Underpants is destroyed. He then lets George and Harold go. Crackers is continuing to get sicker, so Sulu makes him a nest. The four friends watch as Tippy tosses Mr. Krupp around with his foot, laughing maniacally.

George and Harold however can't hear the battle due to the yelling teachers nearby. Suddenly, an old Mr. Krupp arrives and tells the teachers to get the students in class now. The duo discover that the screaming and yelling teachers are themselves in the future, but they're not very nice teachers and are actually teachers that are similar to the teachers they are used to. As it turns out, the vow that George and Harold made about promising to act more mature is what made them similar to the teachers they were used to.

In response, the duo make a new vow to always be themselves. After that, the adult George and Harold disappear, leaving old Mr. Krupp standing there confused. Then, they snap their fingers at him, turning him into Captain Underpants. The duo tell old Captain Underpants to save the present Captain Underpants. He does what he is told, and when he brings Mr. Krupp back down, George and Harold snap their fingers, making TWO Captain Underpantses. They each beat up Tippy and his giant robo-boxers, but Tippy then sets off his nuclear bomb. Tippy then states to the six that the bomb will destroy the entire galaxy, as it is more powerful then a supernova. Suddenly, Crackers and Sulu sacrifice themselves by sending themselves, Tippy and the Robo-Boxers back 13.7 billion years ago. When the three go back, the bomb explodes, causing the Big Ka-Bloosh theory, incinerating Tippy and creating the universe.

13.7 billion years later, George, Harold command old Captain Underpants to gather his clothes, fly into the school, get dresses and wash his face off with water to turn back into old Mr. Krupp. They along with Present Captain Underpants realized that they are stuck in the future without a time machine. Then, Harold points out that Crackers is a girl, because she laid three eggs. The three then decide to take care of the eggs, seeing as Crackers did something for them, so in return, they'll do something for HER. As the three are walking through town possibly going to see if their homes are still around they could stay in, Melvin appears in an octopus suit and grabs Captain Underpants and the boys. They thought they was going to be in danger by Melvin again but Melvin takes them back to the present time from which they left in the first place in Melvin's last invention "The Purple Potty Time Machine", Melvin warns them that something bad has happened since they've been gone.

Chapter 17. The Tyrannical Retaliation of the Turbo Toilet 2000

Meanwhile, the kickball  The Harold 2000 kicked into outer space in book 5 was heading towards Uranus and decapitates The Incredible Robo-Plunger. The juice that came from the Robo Plunger poured into the Turbo Toilet 2000's mouth, reviving him. The Turbo Toilet comes back to life and decides to take vengeance on Earth. He dismantles the Robo Plunger, remakes it into a rocket scooter and flies from Uranus to Earth.

On Earth, the police were searching for George, Harold, and Mr. Krupp for robbing a bank in Book 8. However the police gave up because they couldn't find them (they had traveled back in time to the Cretacious period) and Melvin was very happy due to the absence of George and Harold. Two weeks later though, the Turbo Toilet 2000 invaded and annoyed Melvin, who had almost completed his project. He insulted the Turbo Toilet 2000, who chased Melvin to Jerome Horwitz Elementary School where he hid in Mr. Krupp's office. He notices a toenail from Mr. Krupp, and he tosses it away in disgust. Suddenly, he remembers that Mr. Krupp is Captain Underpants and he could extract his DNA to him. Melvin started searching for the toenail again. Eventually the Turbo Toilet 2000 finds him, but Melvin finds the toenail, converts it to a juice, and drank it. Melvin then gained Captain Underpants' superpowers and destroyed the Turbo Toilet 2000.

Later on, Melvin becomes a superhero. One year later, he has had enough for the citizens were abusing the system, for requests such as help for dropping their wallet in the toilet. Melvin tracks down Captain Underpants, George and Harold using a GPS device he installed in Sulu's robotic endoskeleton. The story returns to when Melvin has took the heroes back to the present. Melvin warns them that something bad is going to happen in two weeks and teleports to the unknown.

When they get home, Captain Underpants flies off to Mr. Krupps house "as commanded by George and Harold" to wash off with water turning back into Mean Mr. Krupp. George and Harold need a lot of sleep due to the fact they had not slept for the past thirty hours. However, their angry parents punish them by making them do chores because they skipped school the previous day in the last book. Unfortunately for them, they forgot the following day was test day so they had to stay up all night and study. The next day, they accidentally oversleep and miss school and the tests.

The next day, Mr. Krupp is surprisingly happy and claims to the duo it's the greatest day of his life since he met George and Harold. He and Miss Calculator give the duo their report cards and it's revealed that because George and Harold had missed the quizzes, they got bad grades and according to Mr. Krupp, there are no makeup tests for the missed quizzes and the final exams have been canceled this year. However, Mr. Krupp reveals that the worst part for them is that George got 62.7% (which is still passable), but Harold got 59.7% meaning George and Harold will be forced to take different paths after the end of the year.

Later that day, George gets the idea of he and Harold using Melvin's time traveling squid suit to go back in time to yesterday morning and take the tests, thus preventing the teachers and Mr. Krupp from giving them all F's on Super Secret Test Day and separating them. When the duo arrive in the past, Harold notices they have created an extra Robo-Squid suit (the one from yesterday), but he and Harold decide to ignore it as Melvin will now have two Robo-Squid suits. George and Harold head to school (feeling happy about going there which they find weird), take all of the quizzes they initially missed, and manage to pass most of the quizzes. When George and Harold return to the treehouse, they discover their actions have created another George and Harold (their yesterday selves). When the yesterday duo wake up, the present day duo explain why they are here and what were they were doing. The George's and Harold's decide to use a system where the Yesterday boys would go to school on even numbered days, and George and Harold would go to school on odd numbered days.

The next day, George and Harold are at home, and run out of money. They create a new Super Diaper Baby comic and go to school to sell it. Ms. Anthrope catches them though, so George tries to claim she is dreaming. She doesn't fall for it and demands Ms. Ribble to send George and Harold to her office immediately. This results in her seeing both George and Harold and their yesterday counterparts, which she is shocked and confused at. Ms. Anthrope believes that what George said is true and goes running out her office in her underwear. Yesterday George and Harold get mad at the original counterparts for coming to school and George and Harold explain they ran out of food and wanted to sell comic books to make money so they can purchase food. Yesterday George and Harold however take the comics away, so they can sell them and tell George and Harold to get out of the school before somebody sees them.

George and Harold aren't happy at being told what to do and try to cause mischief. However they are seen by the other faculty members and, upon seeing George and Harold in the hallway and their yesterday counterparts in Ms. Ribble's room, they instantly believe they are dreaming and proceed in stripping down to their underwear and doing crazy things. Mr Krupp, however, is shocked by the presence of two Georges and two Harolds in the same way he is in Book 5. When the police arrive, they arrest the faculty except Mr. Krupp for indecent exposure, reckless endangerment, resisting arrest, and pantsing an officer. The police are unsure of what to do with Mr. Krupp as he didn't actually do anything wrong, but they eventually admit him to the Piqua Valley Home for the Reality-Challenged.

Twelve days later, the Turbo Toilet 2000 attacks the city, and George and Harold make Talking Toilet costumes and lure the Turbo Toilet 2000 to break into the Piqua Valley Home for the Reality Challenge (as George and Harold couldn't get pass the woman in the front room to see Mr. Krupp). When the two of them find an intercom after the nurse is distracted off somewhere, a quick finger snap is done through the intercom speakers by the duo in order to for Mr. Krupp to become Captain Underpants. Captain Underpants breaks out of the strap jacket taking a red curtain from the window and flies out to take a stand against the TT2000 to fight. The began to battle and then soon after, the Captain is victorious, but one of the Turbo Toilet 2000's tears lands on Captain Underpants' face and he turns back into Mr. Krupp who is then grabbed by the TT2000. Mr. Krupp pleads insanity to the TT2000 to be let go of but TT2000 said he will let him go if he tells him where George and Harold are. So Mr. Krupp directs the Turbo Toilet 2000 to the treehouse of George and Harold, where the Yesterday boys reside. Shortly after he finds the treehouse, the TT2000 breaks his promise of setting Mr. Krupp free and stuffs Mr. Krupp into his stomach swallowing him again like in the second book. The Turbo Toilet 2000 attempts to capture them, but he causes Crackers' eggs to crack and give birth to three strange creatures. At first they take affection to the Yesterday boys, but then they realize that they were in danger. The three hamsterdactyls then attack the Turbo Toilet 2000 and lift him one kilometer above the ground. When the TT 2000 begs to be let go, they do exactly that and drop him, causing him to break apart into many pieces and release Mr. Krupp (who survives due to his super powers). The officers arrive and because Mr. Krupp believes he is having a weird nightmare that he keeps having, they assume that Mr. Krupp is another teacher running around in his underpants that thinks he/she is dreaming, so they arrest him.

To George's disgust, George and Harold realize that the hamsterdactyls must have been the result of Sulu and Crackers breeding. After naming their new pets and putting them to bed, the four boys realize there are too many loose ends in the story (the city is destroyed, the school faculty are in jail, there are two George's and Harold's and the hamsterdactyls think the George's and Harold's are their mommies).

Chapter 18. The Sensational Saga of Sir Stinks-A-Lot

Meanwhile, in a different universe where a planet called Smart Earth orbits around the center star in Orion's Belt, everyone who lives their is highly intelligent due to the planet being made from a slightly radioactive element named Zygo-Gogozizzle 24 that can be mixed with mayonnaise and dill-pickle relish to create a clean-burning fuel source to light up an entire city and serve as a tasty salad dressing.

Even though Smart Earth is inhabited with geniuses, it has many similarities to our planet, having McDonald's, smartphones and the Huffington Post (which on Smart Earth are called Smart McDonald's, smart smartphones and the Huffington Post). One day, one of the smartest scientists at Smart Harvard University (a parody of Harvard) decided to do an experiment mixing Smart Diet Coke with Smart Pop Rocks and a third ingredient to the highly volatile concoction: Smart Mentos. The conduction of the experiment caused Smart Earth to explode, sending chunks of Zygo-Gogozizzle 24 throughout the galaxy, some landing in a pond on Badpun, a grape vineyard, on Pinot, and one piece that approached our own planet's atmosphere, in a small midwestern town of Piqua, Ohio. The tiny chunk crashed through the roof of the Piqua Valley Home for the Reality-Challenged, where George and Harold's elementary school teachers are being held.

Ms. Ribble thinks the piece of Zygo-Gogozizzle 24 is a meteorite, and the doctor warns them not to approach it. Unfortunately, Mr. Meaner, the gym teacher, doesn't listen and eats the chunk. He then becomes highly intelligent after the Zygo-Gogozizzle reaches his mind and supercharges all his brain cells. Mr. Meaner then speaks in a standard British accent and decides to leave the insipid infirmary, but the psychologists block the doors. Mr. Meaner immediately comes up with a plan to trick them and tells them they should take his advice not to follow his advice. The two distracted doctors begin to argue if following his advice not to follow his advice is following his advice, Mr. Meaner slips out the open doors. Ms. Ribble notices her chance to escape, and she, along with all the other teachers, dart past the increasingly frustrated and confused doctors.

Outside, the teachers and staff follow Mr. Meaner up to the hilltop and watch in awe as he looks over the horizon, and announces that it occurred to him that all their recent problems were caused by willful and disobedient children. He tells the teachers to follow his every command and to return to school and act normal. School restarts and it appears everything is back to normal and nothing unusual has happened such as crime happening at the school or Mr. Krupp being snapped into a trance becoming Captain Underpants. Everything was just normal but meanwhile overnight Mr. Meaner goes to an old, abandoned factory near Franz Pond and turns it into a makeshift laboratory. Inside, he creates Rid-O-Kid 2000™, a mind-control potion which turns even the most unruly child into a well-behaved child who follows the instructions of adults. He makes it from a base mixture of sodium thiopental containing liberal doses of butyric acid, tryptophan and Clamato juice and filters the solution through a pile of old, dirty gym socks.

The next day, Mr. Meaner arrives at school with two large spray tanks on his back and a metallic belt with buttons around his waist. After gym class, Mr. Meaner excuses all of the children except for Yesterday George and Yesterday Harold. He orders them into his office and locks the door after them. Inside his office, he sprays Yesterday George and Yesterday Harold with Rid-O-Kid 2000™ from the nozzles of his spray tanks. Yesterday George and Yesterday Harold go to their maths class and are well-behaved. Their maths teacher, Miss Calculator, is pleased with their behavior. For the rest of the day, the other teachers notice how well the boys are behaving and after school finishes, they go to all their teachers and collect extra-credit homework.

Yesterday George and Yesterday Harold return to the tree house, where George and Harold are horrified at the amount of homework they have brought home. The four of them start completing their assignments, but George and Harold keep getting distracted. They work until bedtime. While Yesterday George and Yesterday Harold complete their half of the work, George and Harold barely do any of their halves. Yesterday George suggests he and Yesterday Harold should go to school the following day while George and Harold stay up until 5:00 am completing their work.

The following morning at school, Mr. Meaner also has robot arms and hands, having built a giant mechanical ape suit named 'The Stinky-Kong 2000'. He sprays all of the children in his classes with Rid-O-Kid 2000™, giving them all 'Attention Superfluous Lethargy Syndrome (ASLS). Mr. Krupp is delighted that Mr. Meaner has transformed all the children. Ms. Ribble asks if Rid-O-Kid 2000™ is dangerous and Mr. Meaner explains to her that it only affects children and that adults are immune to it.

A few days later, George and Harold have caught colds due to staying up late to complete the homework Yesterday George and Yesterday Harold have brought home during the week. They decide to watch TV and come across a TV advert for Rid-O-Kid 2000™ featuring Mr. Meaner, which says:

"Are your kids annoying? Do they fight and whine and complain all the time? Do they refuse to eat anything but macaroni and cheese? Are they sucking the LIFE out of you? Well, Rid-O-Kid 2000™ is here to help. Our scientifically proven formula will transform even the most wilful child into an obedient, respectful and hardworking slave– er, I mean, angel. And Rid-O-Kid 2000™ has a full day's supply of Vitamin C, so you can feel GOOD about dosing your child with a narcotic that has never been tested for long-term effects. So turn your brat into a brown-noser... with Rid-O-Kid 2000™. Rid-O-Kid 2000™ - the cure for childhood."

George and Harold dress up as an adult and go to school to find out what's going on. They see all the students acting as slaves for the teachers by doing their work for them, giving them messages, shaving their beards, plucking their eyebrows, giving them haircuts, filling out their tax forms and washing their cars. Harold exclaims that the teachers must have turned all the students into mindless slaves.

The disguised George and Harold then manipulate the children into doing the opposite of what they have been told to do, such as washing the windows wrong, filling their cars with cottage cheese and humiliating the teachers. When the teachers and staff noticed this They along with Mr. Krupp try to find out who is responsible for this but all the children in a trance could tell them that it was a grown up. Mr. Krupp then tells Mr. Meaner about what has happened and this angers him to go out and get to the bottom of whats going on and to find who caused the prank so he rushed to his car that was filled with cottage cheese and drove off the school premises to find the gown up who caused this. He came across a group of kids in the trance who were watering the inside of the house, mowing the garden and painting the lawn. He asks them who told them to do all those things and all the children could say was a grown up but didn't say who the grown-up was. Mr meaner rushes back to the car angry and drive off back to the factory going to his invention with new modifications. He feels that a kid has caused this but he doesn't know who the kid is.

Later he returns in his ape suit causing havoc in the town of Piqua unleashing the foul odor everywhere. Present Harold and George who are still sick witnessed what was Mr. Meaner was doing, however, they couldn't smell so the stench has no effect on them, however, Harold and George were almost better and that wasn't a good thing so they went to their parents who were having dinner with their yesterday counterparts. The Present counterparts left in a deep depression. Present George then had an idea. So he and present Harold rushed to Melvin's house which the garage was open and they took off with the Glow in the Dark Time Traveling Robo Squid.

Later After Present Harold and George were in the future meeting their future counterparts and meeting the family they return with their future counterparts in the present timeline meeting Crackers and Sulu's children. Adult George and Harold tell their younger selves to stay in the clubhouse and rest up for they have already been through a lot.

Adult George and Harold rush to Mr. Krupp's house needing help. As they snapped their fingers several times, Mr Krupp however wasn't coming to his trance into becoming his alter ego "Captain Underpants due to his face and head being wet at the time" Mr. Krupp wanted them to go away because to him he assumed they were acting like kids but as this was happening Mr. Meaner overheard what Mr. Krupp said and he grabbed the two adults and he beat them using his ape suit. Mr. Krupp demanded him not to kill them cause he didn't want any blood on his lawn. Adult George and Harold were nearly in a lot of pain but as they finally noticed that Mr. Krupp's Face was dried up and they saw that there could be their final opportunity so they quickly snapped their fingers at Mr. Krupp and he finally came into his trance becoming the amazing Captain Underpants to save his friends. Captain Underpants charged after and battled Mr. Meaner in his ape suit and Mr. Meaner was defeated for now and taken to jail.

The next day after eating an egg salad sandwich with pickle relish, Mr. Meaner aka Sir Stinks-A-Lot turns into a blob (because the egg salad contains mayonnaise and he added pickle relish; this would create Zygo-Gogozizzle 24). He then causes havoc downtown wanting revenge on Captain Underpants for being locked up. Captain Underpants returns to fight him back, but when Old George and Old Harold are captured, Captain Underpants couldn’t save them, as Sir Stinks-A-Lot turns him back into Mr. Krupp with a lot of water, therefore falling down (he was still unharmed because of his superpowers). Sir Stinks-A-Lot then extracts the superpowers as well as the effects from the 3D Hypno Ring ceasing the existence of Captain Underpants from Mr. Krupp. Mr. Krupp (dressed as the fallen hero Captain Underpants) then runs off screaming in terror as Old George and Harold telepathically calls for younger George and Harold who were sleeping but Tony, Orlando, and Dawn, who are completely awake caught onto the call and came to the rescue. They find Mentos, Diet Coke, and Pop Rocks, making Sir Stinks-A-Lot explode. Luckily, the three hamsterdactyls and Old George and Old Harold are unharmed, as well as Mr. Meaner.

Things were back to the way they were, and as young George and Harold return their older counterparts to their own time, they find that Mr. Krupp didn’t turn into Captain Underpants at the snap of a finger, because Mr. Meaner erased Captain Underpants from existence. As a woman was passing by jogging listening to music and snapping her fingers, Mr. Krupp was still as mean as usual yelling at the woman passing by. George and Harold and their older counterparts decided that they were not going to contribute to the plot and fix the problem which indicated that they were going to move on without Captain Underpants. George and Harold with Melvin's invention "Glow in the Dark Time Traveling Robo Squid." return their older selves back to their future timeline with Tony, Orlando, and Dawn. George, Harold and the 3 offspring of Crackers and Sulu take off once more with the Time Traveling Robo Squid going on a new adventure back in time to save Crackers and Sulu to meet their children.

Chapter 19. The End.

Yesterday George and Yesterday Harold were back to normal now that Mr. Meaner has been defeated. They wake up going back to their tree house come to find out that Tony, Orlando, and Dawn are gone. Seeing that they feel that everything is going to be okay, Harold feels that he and George should make another Captain Underpants comic book, but George decides that he and Harold should do a comic book featuring Dog Man instead and move on without Captain Underpants Comics as well as Mr. Krupp being Captain Underpants himself
