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. When the player start out, He/she appear to be on some kind of airship that appears crashed.

How to unlock
To unlock this galaxy, Mario must beat the level "Faster Than A Speeding Penguin" in the "Sea Slide Galaxy", as well as "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, Mario will have to feed the Hungry Luma, and the way to the Sand Spiral Galaxy is revealed.

Crashed Airship
This is just an airship that seemingly crashed into something or was blasted. Mario starts out here and continues to the sand planet.

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.

Moon and Spiral Rock
This is a small moon with a large spiraling rock spinning around it. Mario must cross this rock while avoiding mines to reach the moon where the power star is.

Choosing a Favorite Snack
The goal in the level is to get through a tunnel filled with quicksand. The player starts at a broken airship, and, after the Magikoopa on board it warps ahead to the tunnel itself, Mario can take a Sling Star over to the main area. Here he has the choice of becoming Boo Mario or Bee Mario. Boo Mario can float infinitely over the quicksand but must watch out for the Boos and the spotlights. Bee Mario will have an easier time avoiding the enemies, but cannot fly infinitely and must make landings on certain sections.

Once Mario exits the tunnel, he will be launched out the other end of the tunnel to a small area, where can get a Rainbow Star to become invincible and jump across rotating platforms to the moon in the center, where the Power Star awaits. If Mario still has the bee suit, he can simply fly to the power star.

The Magikoopa in the beginning of the level will pursue Mario for most of the stage unless Mario obtains the boo suit or if it is defeated. It moves too fast for Mario to attack, so the player must use Star Bits to stun it before the Magikoopa can be defeated.
