Source-derived summary

The Mumbly Cartoon Show is an American animated television series produced by Hanna-Barbera Productions and featuring the titular character, Mumbly, a cartoon dog detective. It was broadcast on Saturday mornings on ABC from September 11, 1976 to September 3, 1977 as part of The Tom & Jerry/Grape Ape/Mumbly Show. This compilation packaged reruns of the 1975 The Tom & Jerry/Grape Ape Show with Mumbly as a new component.

In the show, Mumbly is a private eye dog in a trenchcoat, who works with a human detective, Chief Schnooker, to catch criminals who often sport alliterative names. 16 episodes were produced. Mumbly was voiced by Don Messick, and Schnooker by John Stephenson.

The show was not a ratings success, and only lasted one season. However, in the next season, Mumbly was included in Hanna-Barbera's second crossover show, Laff-A-Lympics, on the villainous "Really Rottens" team. Mumbly was not a villain in his earlier show, but the character was a substitution for the actually-villainous Muttley from the 1968 series Wacky Races, who could not appear on Laff-A-Lympics as those characters were co-owned by Heatter-Quigley Productions. A predecessor to Muttley and Mumbly is the dog Mugger, who appears in the 1964 movie Hey There, It's Yogi Bear!.
