Space Junk Galaxy

The Stardust Galaxy is going to appear on the upcoming game Super Mario Galaxy.This Galaxy has a more futuristic/space theme. A lot of the objects are silver or blue and it has a spaceship in it.

The Float Star is used much more than in other galaxies. Also Toads are on a big platform covered in crystals, if Mario frees the Toads trapped in the crystals a Mushroom-shaped spaceship will appear taking Mario to the next location.

The last unique feature of the galaxy is that it has a path that builds itself when Mario approaches it, but crumbles after he walks on it.
