Sweet Sweet Galaxy

The Sweet Sweet Galaxy is one of the galaxies that Mario traverses in Super Mario Galaxy. It appears after the Hungry Luma next to the Terrace has been fed full of Star Bits. It features moving platforms with cookie-cutter-shaped holes in them and appears to be made up primarily of titanic sweets and desserts. It takes place in the atmosphere of a planet, so if Mario falls through a hole he will fall to his death. The stage also has electric barriers which have to be jumped over; if Mario touches one, he will get stunned temporarily and lose one point of health.

The music of the Sweet Sweet Galaxy is a remix of the second overworld theme from Super Mario Bros. 3.

Main Planet
This is a large planet made of cake with moving, chocolate roads with shapes cut out of them. Mario must run across these roads avoiding the holes to reach the Power Star. The roads range from a simple linear path to a curved path with big shapes cut in them.

Small Cake Planet
This is a small platform where the Power Star is held. It has three layers that seem to be lemon, mint chocolate, and strawberry. It has a circle of strawberries that Mario can spin to get Star Bits.

Rocky Road
Mario has to run and jump way forward while avoiding holes and electric barriers until he gets to the cake with the Power Star on top. If he falls after making it at least halfway to the Power Star, he will not have to start all the way at the beginning, but will resume his quest from where the Toads are standing.

Trivia

 * The name of the only level in this galaxy comes from the name of a dessert, rocky road, which is chocolate mixed with marshmallows, and in some countries, nuts or other ingredients. In the United States, it is also a well known ice-cream flavour.
 * This galaxy is intended as a flashback to the mechanics of past Mario games to remind long-term fans that the unorthodox Super Mario Galaxy is still a part of the series.
 * The galaxy can be accessed without using the Launch Star via a glitch; after talking to the filled-up Luma to make the Launch Star appear, Flying Mario can be used to access the portal.
