Tuff is a crazy boy who lives in King Dedede's castle along with his older sister Tiff, his mother Lady Like, and his father Sir Ebrum. He often likes to tag along with his sister and is almost as fast as she is. Tuff isn't really the smartest one though, he's immature and often found getting into trouble. He's also very stubborn and rarely thinks before he acts. Tuff never means any harm, but his actions often have very annoying consequences. He often enjoys hanging around with a group of three Cappy kids: Spikehead, Iroo, and Honey. Tuff has also befriended Kirby.
Tuff's appearance is a little different then the rest of his family. He has orange skin with dark olive clored shoes/feet. He has orange and green hair which is grown out way too much, covering his eyes completely. He wears bright purple pants with kind of a jumpsuit-like red strap.
