Chespin is a bipedal, mammalian Pokémon. It has a light brown front with dark brown arms and three triangular markings on its face. There is a tough, green shell covering its back, which extends from its head to halfway down its tail. There is a small, off-center hole in the shell on the back of Chespin's head. The shell can protect Chespin from powerful attacks. Around the face, the shell has four leaf-like spikes, and one split into three parts on the back of its head. These quills are typically soft, but Chespin can stiffen them and use them for attack as well. Chespin's oval eyes are brown, and it has a triangular red nose and rodent-like incisors. Its arms have three fingers, while its feet have two long claws. The visible part of its tapered tail is orange. Despite having a curious nature that tends to get it in trouble, Chespin keeps an optimistic outlook and does not worry about small details.[1]
