Dumb Donald is a member of the Junkyard Gang. In the Junkyard Band, he plays the trombone (made from a long pipe and a Victrola horn machine)
Dumb Donald, as his name suggests, is very simple-minded and loud, but means well and can be very nice at times.
Dumb Donald is a lanky African-american teenager.
He wears a pink knit-cap which covers his face (aside from his eyes and mouth), a green long-sleeved jersey with 2 blue stripes on each sleeve (which is three sizes too big), blue pants, green socks and blue sneakers.
In the movie, his appearance is completely unchanged.
- In the original cartoon, Dumb Donald's full face was never seen, but in the movie it was seen in live-action (Dumb Donald's face was only floating eyes and a mouth in the cartoon world)
