Gelatinous Cube

The Gelatinous Cube is a creature that lived with the Serfsons.

History
When the family were talking about selling their possessions, Marge suggested that the Gelatinous Cube must be worth something. The Gelatinous Cube then responded, asking if this was about what happened to the cat, whose skeleton was inside him, as the Cube had told the cat not to sit on him.

Later, Homer takes Maggie out of him before the Cube could dissolve her. After Homer was freed from his toenail cage, the Gelatinous Cube asked if he could eat the toenails, then did so.
