Six-legged mutant death rat

The Six-legged mutant death rat is a presumably extinct cryptid discovered by Chadswick Longcocksworth in his exploration of the Avon Grove Jungle. The beast was a terrifying massive rat with 4 specialized front limbs, including raptorial claws, and 2 strong legs for persuing its prey. Skeletal analysis suggests that this animal could walk on its hind legs, and had similar brain capacity to that of a human.
