Sand Spiral Galaxy

The Sand Spiral Galaxy is a galaxy in Super Mario Galaxy. This galaxy is a large barrel with a rapid sand river. This galaxy has many Boos and Bats.

This galaxy is unlocked when Mario completes 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.

Planets/Areas
NOTE: Unless otherwise noted, all names are unofficial.

Wrecked Airship
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
This is a large pipe-like planet that is filled with sand. Mario must navigate through the obstacles and avoid falling into the sand by either using the Bee Mushroom or the Boo Mushroom. The tunnel's exit marks a checkpoint.

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.

Mission
This galaxy contains only the following mission.

Trivia

 * If Boo Mario tries to fly up to the spiral area instead of taking the Sling Star, his abilities will disappear before he lands on the platform. This is due to how bright the moon is, as noted by a Toad.
 * Near the entrance, a Red Toad is seen near a Boo Mushroom. Interestingly, the only Red Toad in the Toad Brigade is Captain Toad, who is always seen with his headlamp and backpack on. He still reacts in the same scared way Captain Toad would upon seeing either of Mario's powered-up forms while other Toads in the area do not, indicating it may still be him.
 * Like Sweet Sweet Galaxy, this galaxy can be accessed without using the pink Launch Star left behind by the Hungry Luma via a glitch: after talking to the Hungry Luma to make the Launch Star appear, Flying Mario can be used to access the portal instead.
