Meep

The Meeps were a species of furry creatures, more dangerous than they looked.

History
Originally, the Meeps were a highly advanced peaceful race, envied throughout for their happiness. The race was mutated by the rays of a Black Sun, which turned them into conquest hungry, planet-grabbing killers. (DWM: The Star Beast) Eventually, they returned to their peaceful nature, though they were still a cunning and resourceful species, taking advantage of their harmless nature. (EDA: Placebo Effect)
