Chespin is a bipedal, mammalian Pokémon. It is primarily light brown with darker arms and three triangular markings around its face. It has oval, brown eyes; a triangular, red nose; and rodent-like incisors. Its arms have three fingers, while its feet have two long claws. Covering its back is a tough, green shell, which extends from its head to halfway down its tail. The tip of its tapered tail is orange. There is a small, off-center hole in the shell on the back of Chespin's head and, around the face, the shell has four leaf-like spikes. On the back of its head is another spike split into three parts.

Chespin's shell can protect it from powerful attacks. The quills on its head are usually soft but can be stiffened for attacking as well. Despite having a curious nature that tends to get it in trouble, Chespin keeps an optimistic outlook and does not worry about small details. By consuming tons of berries, the bark shell that covers Chespin's head and body will grow sturdier. It has been recently seen living in the Terarium of Blueberry Academy.

Evolution
Chespin evolves into Quilladin, which evolves into Chesnaught.
