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.

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.

Trivia

 * The name of the only level in this galaxy comes from the ice cream flavor rocky road, which is chocolate ice cream containing pecans, marshmallows, and chocolate sauce.
 * 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.
