Dumb Donald is the least inteligent member of the gang. He wears a pink stocking cap that covers much of his head, and a long-sleeved green jersey three sizes too big. His parents house was robbed once.
He is simpleminded, but well-meaning. But in the real world, he is intelligent and actually has a face.
- In the 2009 series, his pink stocking cap was replaced by a blue baseball cap.
- In the same series, he was shown without stocking cap, and he has no face: just floating eyes and mouth.
- At the live-action movie, he finally learns to live without his hat.
- At no time in the original series, was he ever seen without his cap.
