Chespin is a mammal Pokémon. It has two layers; the above is painted green and the under is dyed brown. On the top of its ears, nose and tail the color is orange.
When Chespin evolves into Quilladin, the hard spikes on its body grow even sturdier. Despite its prickly appearance, Quilladin is considered a gentle Pokémon that avoids battle. Quilladin uses its hardy shell to repel attacks and strike back with its pointed spines.
