Abbagoochie

Although originally only found in Costa Rica, these savage primates were imported to West Virginia to act as pest control, though multiplied out of control and are now considered a threat to human safety. They are sometimes called 'dry land piranhas' because of their intense feeding frenzies, in which they can devour animals many times their size. If cornered, the creatures will eat themselves rather than let themselves be captured, though it is unknown what sort of instinct drives them to do this.
