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

Biology

Meeps were spherical creatures with large ears, a short nose and almond-shaped eyes. Their dense fur concealed a pouch and their blood was green. (DWM: The Star Beast) They had white fur and pink feet and hands. (EDA: Placebo Effect)

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)

Members of the Slitheen family impersonated Meeps. (NSA: The Monsters Inside)

During the 40th century, the Meeps successfully petitioned the Galactic Federation to stop the production of stuffed Meep toys, finding them offensive. (EDA: Placebo Effect)

In the Olympics of 3999, several Meeps were participating, including one who competed against Kyle Dale in the discus throw. (EDA: Placebo Effect)
