Produced by Hanna-Barbera, The Mumbly Cartoon Show focused on a dog detective named Mumbly (who is also featured in the "Laff-a-Lympics" cartoon). Mumbly dresses in a trench coat, drives a beat-up old car and solves crimes using his dog senses. His character was modeled after the TV detective Columbo in terms of appearance and mannerisms.
