Biligruff is a Pokémon based on a goat, like its pre-evolution the Pokémon has a brown coat of fur and a defining hump around its shoulder region giving the Pokémon and imposing stance. Biligruff keeps its head low making it appear ready to charge at any given moment, its forelimbs are very developed with clear muscle outlines, its hooves are larger and more complex now appearing to have a toe-like protrusion at the front of each hoof that is actually a very thick layer of keratin. The Pokémon's horns have developed further and curve slightly forwards although are mostly straight.
The Pokémon's ears are longer now and curve backwards, due to each ear having a dark stripe of fur they have the slight appearance of horns making some people mistake the Pokémon as having four horns. the spotted pattern from its pre-evolution is gone and instead the Pokémon has a smooth gradient from the light brown of its upper body to the dark brown of its ankles and tail. Its tail is spade-like in shape with a large amount of fur at the tip. The tip of its tail is completely white and is the only part of the Pokémon's fur that is white as the stripe on its back is gone.
