Deep Dark Galaxy

Deep Dark Galaxy is a ghost-type galaxy in Super Mario Galaxy, like the Boo's Boneyard Galaxy and the Ghostly Galaxy. However, the main planet in it has a beach with many Toads and crab-like enemies. There are also Magikoopas near it. The thing that makes it "spooky" is that there is an underwater cavern (it's rather dark, giving the Galaxy its name) filled with "ghost ships". There are very few planets aside from the big, main one. This is also the second appearance of Guppy.
