In the 70s, Hanna Barbera had to reinvent and put on new shows. However, if we remember Mumbly, it was more or less good, depending on the episodes.Mumbly is a dog which does his best to solve crimes. As Mumbly resembles a bit like Columbo, his chief detective has rather a Kojak attitude (looks like him too !) and sometimes wants to have credit over cases that Mumbly solves all the way. But hey, the dog s not so stupid and gets the credit where it s due.Saw it mostly in French. Francis Lax did the dubbing on the chief officer (the series was dubbed in Paris). However, despite Don Messick s excellent dog laugh (same as Mutterly), in french, it was not all that good...Plots were not great, a rehash of what Hanna Barbera did better way past. And Mumbly was such a bore sometimes, wondering if he can let the job to a similar laughing canine like Mutterly...To see if you have time to kill, however, series not the greatest from Hanna-Barbera... and Mumbly was better in Laff A Lympics...
