Tatanga Jr's Heavy Metal Castle

Tatanga Jr's Heavy Metal Castle is the third boss world in Super Luigi Galaxy. It is where Tatanga Jr lurks with his horrible mega suit. Luigi starts on an elevator that you ride the whole level. As you travel on it, you fight enemies, dodge obstacles of all sorts, and even fight a mini boss.

The Mini Boss
About halfway through the level, you encounter a mini boss. The monster is a fiend called Iron Man. The monster is a living clumpy metal suit that has bombs for hands. He tries to smash Luigi, throw bombs at him and ultimately be a massive pain. You just defeat him by hitting him with fire from Reddy. He will die with a loud crash and leave lots of crystals.

The Boss: Mega Suit
The boss for this area is Tatanga Jr in a metal suit. His suit is a more advanced version of Iron Man's. He will do the same attacks and will stomp so hard, it stuns Luigi. He can be defeated by ground pounding on him when he dives into a wall. Do this 3 times and he will escape and you depart with the grand star. You soon find Tatanga is invading the next World.
