Mumbly is an anthropomorphic dog, who captains the Really Rottens team in the Laff-a-Lympics.

Physical appearance

He has bluish-white fur and his face usually has a cunning expression, with a few teeth showing when his mouth is closed.


He either mutters and cusses under his breath, or snickers when things are going well for him and badly for others.

Appearances in other media

Despite his strong resemblance to Muttley of the Wacky Races, Mumbly has his own history. He was originally Lieutenant Mumbly, a heroic police detective from The New Tom & Jerry/Grape Ape/Mumbly Show. He differs from Muttley because he has light ears instead of black, and because he is more of a leader. The Dread Baron, a dopplegänger of Dick Dastardly, is his follower, rather than the other way around.
