Pichu is a small ground-dwelling rodent. Its fur is very short, and it is pale yellow in color. The tips of its large ears are black, and it has additional black markings on its neck and tail. Its tail is short, but still bears some resemblance to the large lightning-bolt structure it will develop later on in life. It has pouches in its cheeks, which are pinkish coloured and used for storing electricity. Its nose is extremely small, almost like a dot. It is classified as a quadruped, but many have been known to walk easily on their hind legs
