After the ABC run ended in 1967, cartoons from Magilla Gorilla and Peter Potamus shows were syndicated together.

A similarly subtle sponsor reference appeared in the Magilla Gorilla theme song lyrics: "He's really ideal".

Episodes generally consist of Peter and So-So exploring the world in his hot air balloon, which has a gondola shaped like a boat and is capable of time travel at the spin of a dial.

The episode Cleo Trio is on the Hanna Barbera 25 Cartoon Collection DVD, part of The Best of Warner Bros. series.

On November 1, 2016, Warner Archive released The Peter Potamus Show- The Complete Series on DVD in region 1 as part of their Hanna–Barbera Classics Collection.
