Sweet Mystery Planet
This planet is entirely composed of food-like platforms. There are few enemies in this galaxy, and a twisty Matter Splatter path that can only be revealed with the use of the Bulb Berry. The Comet Medal is found on an invisible platform to the right after passing the first curved platform. There are a few moving platforms and some flowers can be found in one area. To reveal the Launch Star that leads to the next planet, the player must turn all the Flipswitch Panels yellow. This is the starting planet for all of the missions.
When the player uses the Launch Star from the first planet, they'll end up on the final planet in the galaxy. At first, the player will see this planet shaped like a present, but as they approach it, the gift unwraps and reveals a cake. When the player lands on it, the cake will disappear. The only way to see it again is to use the Bulb Berry. Choppahs can be encountered here. The Power Star is at the top of the cake.
Green Star 1
The player will redo the Bulb Berry's Mysterious Glow mission. The first green star is located under a Matter Splatter platform. To get it, the player must use Bulb Yoshi and stand on this platform. Then, they must wait until the Bulb Berry's effects wears off and fall to get the Green Star. This Star can also be reached by long jumping at it with Luigi.
Green Star 2
The player will redo the Bulb Berry's Mysterious Glow mission. The second Green Star is located near the location of the Comet Medal on the Sweet Mystery Planet. To get it, the player has to perform a Flutter Jump towards the star located to the right of the medal.
