Sand Spiral Galaxy
This galaxy is unlocked when Mario complete the mission Faster Than a Speeding Penguin in the Sea Slide Galaxy and Luigi and the Haunted Mansion in the Ghostly Galaxy -- this is because that star is supposed to "introduce" the Boo Mushroom. Once Mario does so, a Hungry Luma will appear behind the Engine Room. Mario needs to feed the Hungry Luma, and the way to the Sand Spiral Galaxy is revealed. The galaxy's only mission can be accomplished by use of either the Boo Mushroom or the Bee Mushroom.
NOTE: Unless otherwise noted, all names are unofficial.
This is just the front half of an airship that seemingly crashed into something or was blasted. Mario starts out here and continues to the sand planet. It is more likely that it was blasted by some sort of weapon due to the scattered debris floating nearby and the fact that the division where the two halves would meet is made up of jagged, protruding chunks of deck, wood, and some individual wooden beams that would support or make up the decks. On the airship there is a Magikoopa.
Sinking Sand Planet
Spiral Moon Planets
This is a small moon with a large spiraling planet spinning around it. Mario must cross this spiral planet while avoiding mines to reach the moon where the Power Star is.
If Mario gets across the entire Sand Planet as Bee Mario, he can fly to the moon. He will have to stop on the platforms once or twice while taking this shortcut. If Mario reaches the area as Boo Mario, the power-up wears off. The Purple Toad explains that the moonlight is too bright.
This galaxy contains only the following mission.
