Aim and Go Galaxy

Star 1: The Act Begins
Mario starts in a spacious circus tent, where he meets Springboard, a friendly circus owner. He tells Mario of the devastation and depression that was bought to the people after Bowser wrecked their galaxy. Mario offers to bring some joy to the people's hearts, and thus agrees to start a circus show, which (in this star) consists of Mario blasting himself from target to target with cannons. Once he's finished, he returns and Springboard offers Mario the star for his services.

Secret Star 1: Impossibility? Nope.
There is a clearly visible, but impossible seeming target in the course, as it is very far away from Mario. However, if you speak to Springboard for more than 10 times after he signals the beginning of the course, he will get tired and reveal a circuit-board in the circus tent which once solved, will place the target in a much more manageable position. The star is on the bullseye of the target.

Star 2: Precise Plum-Picking
As 'Act 2', Mario must use cannons to be fired in a straight line in such a way that the path lines up with small grassy moving islands that contain a plum tree each. Mario must collect the plums in question, and return to the circus tent by a sleigh pulled by deer which love plums, and thus a plum is used up to make the deer pull the cart. He is again rewarded with a star.

Secret Star 2: Perilous Plum Plaza
Somewhere in the stage, there is a circle of plum islands, and if Mario falls here, he will be launched into a street filled with mutated plums which try to kill Mario. If he makes it, he will recieve a star.

Star 3: Power Restoration
Mario must restore power back to the whole Aim and Go galaxy by finding a power source inside the 'Sea of Wonders', a translucent rainbow sea which is reached by many cannons.
