The catgator is a large dark green reptile that is about seven or eight feet long from snout to tail. It is a squat, short creature and moves with its body close to the ground. Its back is lined with ridges and it has a flat head with barbel whiskers coming from the snout. The catgator's mouth itself is lined with sharp teeth, and its tail has a small fin at the end.
Catgators are the bottom-feeders of the swamp. Although they appear to be ferocious animals, they are actually pretty docile toward humans. To most people, the catgators are considered extremely revolting creatures, but to the folks of the Foggy Swamp Tribe, the catgators are lovable pets and are given names such as Slim and Derby. Catgators will eat anything they can get their teeth on, except for the large bugs which inhabit the swamp.
