Stuffy is a slender stuffed dragon with a red collar round his neck and rosy cheeks. He sometimes appears in other outfits, such as a pirate costume in the episode All Washed Up and winter clothes in Chilly Gets Chilly.
While being brave and intelligent sometimes, Stuffy is rather clumsy but he doesn't always trip and fall successfully. Whenever he does it everyone often laughs at him because they think it is funny. But when Stuffy causes a frequent accident during a patient's check-up or at any time, he seems loyal and truthful to Doc or anyone else.
Role in the series
Stuffy is a stuffed blue dragon who always tries his best to be the bravest dragon of all. He unexpectedly hurts himself when Doc and the toys are playing a game in the episodes The Right Stuff and Un-Bur-Able. Stuffy says he isn't afraid of anything (except spiders) and when he tells himself he is brave, a noise startles him.
Stuffy's favorite game it protecting castles from monsters and brave knights. He dislikes tea parties, until he is part of it in the episode Tea Party Tantrum, when Doc and Lambie laugh at him for sipping from his tea cup loudly. Also in the episode All Washed Up, Stuffy and Lambie are pretending to be pirates in the game "Find the Hidden Treasure" (because of this, Stuffy is dressed as a pirate in the game).
