A creature from Star Trek that breeds like crazy. Wiped out by the Klingons, but a starship from the future brought one back into its own time, thus restoring the species.
A wad of curly hair found in the bathtub. If left unattended, tub tribbles will multiply asexually. In a very quiet bathroom, you can often hear them make soft cooing sounds. They will frequently grab and cling when handled, but usually they do not bite.
1. PURE EVIL
2. A ball of fluff that procreates rapidly and drains an entire species of resources until they collapse. The species does not notice because the tribbles are "cute."
