Mr. Small is a tall, fluffy creature. He wears a rainbow-patterned shirt, black bellbottoms, and blue and yellow sandals. White fluff covers almost all of his body. This fluff is more plentiful on his forearms, feet, and head. He also has a small ponytail to keep his hair tied back, which may or may not be long, as it was when he was younger. His eyes are round and coloured yellowish-green and red, almost like a green olive.
Back in Junior High, his hair was very long, going mid-back. He also used to have a pink shirt with a sideways Yin Yang symbol on it, which he wore with bluish-white jeans.
