Bunnelby is a small, gray, rabbit-like Pokémon. It has large, gray, brown-tipped ears with pinkish fur on the inside. It has a large, gray head and large eyes with white sclera and black pupils. It has a small pink nose and gray fur that sticks out on the cheeks, along with large white teeth. Its neck is surrounded by brown fur. It has a gray body with a gray tail and small brown spots on its hind legs. Its front paws are completely gray, while its hind paws are gray with brown toes. Bunnelby's ears are strong enough to shovel dirt and chop tree roots, just like seen in the XY anime.
Bunnelby can be evolved to a Diggersby at level 20.
