Magla

Believed by some to be a lifeless planet, Magla is actually an 8,000 mile wide spaceborne amoeba with a crusty shell.

The book Origins of the Universe, by Oolon Colluphid, mistakenly identifies Magla as a planet and claims that its conditions make it incapable of supporting life of any kind.
