Rock Monster1

This article is about the species from Planet U.  For the similar species from Earth, see Rock Monster (Earth).

Rock Monsters are the main inhabitants of Planet U, living underground and feasting on brickonium alongside the rarer Ice Monsters and Lava Monsters.  They are able to camouflage themselves by hiding amongst the rocks.  It is believed that they were once an intelligent and advanced civilization but have since degenerated due to unknown causes, perhaps reality television.
