He is a woolly mammoth-like creature, without tusks or (visible) ears, and has a long thick pointed tail, similar in shape to that of a dinosaur (like a sauropod; in particular an Apatosaurus) or other reptile. He has long thick brown hair and a trunk, or "snuffle", that drags along the ground. He is Big Bird's best friend and has a baby sister named Alice. He also attends "Snufflegarten".
