Black Hole

A Black Hole is a major obstacle in the Super Mario Galaxy series and replaces pit falls.

Effect
In the real world, it's said that items in a black hole experience "Spaghettification" when being sucked in. In the SMG series, the player gest sucked in. Seems like Earth. Then, the spaghettification happens, and then POOF! As the player gets inside, that character disappears in a puff of dark smoke, and loses a Life.
