The swamp womp rat, also called a "swamp womper", was a variety of womp rat found on Cularin and a few fringe worlds, where they were considered a nuisance. They had muddy brown fur and long whiskers, and lived in swamps and bogs. Swamp womp rats were ambush predators, and attacked in large packs numbering up to a dozen. When they detected prey, they would swarm savagely over them, overwhelming them with numbers and trying to drag them under the water. They were skittish creatures, and would back down from dangerous creatures or surprising lights and noises.
