Pachirisu are squirrel-like Pokémon. Their fur is white with a faint blueish tint and have a light blue stripe which starts from their forehead and goes all the way down to the tip of the tail. A large white tooth grows out of their mouth. Their eyes are a deep gray. Their cheeks and eyes are similar to that of a Pikachu, but the cheeks are yellow instead of red. Pachirisu have tails that are almost twice as big as they are, with three spikes at the top of the curl, which it can shoot charges from. Their arms and legs are very short. Still, they can run incredibly fast, a trait usually associated with Electric-types.
