Glorp

Glorps are theorized to be an evolved form of gelatinous cubes that develop over a long period of time being exposed to raw mana in the wild. They live simple lives and are moderately-intelligent. In observing humans and other bipedal races, most of them choose to anthropomorphize themselves.
