Bibarel are large, bulky, brown beaver-like rodent Pokémon, and more bipedal than their pre-evolution. Bibarel have tan "masks", on their faces and rumples on the sides. There are tan "bibs" on their chests, and they have large, broad dark-brown tails with a wavy tan pattern on them. Their hind feet are bigger than their forefeet, with a tan-colored paw pad on the underside. Bibarel, like their prevolution, have pronounced teeth, of which Bibarel uses to chew through wood.
