Mumbley versus Muttley

Mumbly appeared on the animated series Tom and Jerry/Grape Ape/Mumbly Show (1976) and The Tom and Jerry/Mumbly Show (1976–77). He made a brief cameo appearance in an episode of Dynomutt, Dog Wonder (1976). Ironically, Mumbly later appeared on the opposite side of the fence as the captain of the villainous Really Rottens on Scooby's All-Star Laff-A-Lympics / Scooby's All-Stars (1977–79), alongside Dread Baron, who bore a great resemblance to Dick Dastardly.

Muttley first appeared in Wacky Races in 1968,^[3] as the sidekick of the accident-prone villain Dick Dastardly. While Dick was created as the equivalent of Professor Fate from the 1960s movie The Great Race, Muttley mirrored the film's character of Max Meen. Dick and Muttley were paired together in various later Hanna-Barbera series as bumbling villains. He is a mixed breed dog, identified in the Wacky Races segment "Dash to Delaware" as a mix of bloodhound, pointer, and hunting dog. [link]
