Peter Potamus

Peter Potamus is a purple animated hippopotamus that first appeared in the 1964–1966 animated television series The Peter Potamus Show, produced by Hanna-Barbera and first broadcast on September 16, 1964.

The Peter Potamus Show is divided into three segments: Peter Potamus and So-So, Breezly and Sneezly and Yippee, Yappee and Yahooey. Peter Potamus was broadcast as a companion series to The Magilla Gorilla Show. Both series premiered in first-run syndication before being picked up by ABC in January 1966. Peter Potamus ran on Sunday mornings and The Magilla Gorilla Show went to Saturday mornings before moving to Sundays the following year. At that time, the Breezly and Sneezly segment was swapped with Ricochet Rabbit & Droop-a-Long, a segment on The Magilla Gorilla Show. After the ABC run ended in 1967, cartoons from Magilla Gorilla and Peter Potamus shows were syndicated together.

The Ideal Toy Company sponsored the television series, and during the original run of the cartoon, the closing song ended with the phrase: "And there he goes Peter Potamus, our ideal". A similarly subtle sponsor reference appeared in the Magilla Gorilla theme song lyrics: "He's really ideal". Early promotional materials for the series carried the title Peter Potamus and His Magic Flying Balloon, but that title never appeared on screen. The original Peter Potamus series was broadcast on the cable TV channel Boomerang, often as part of its anthology series Boomerang Zoo.

Peter Potamus and So-So
The main segment features Peter Potamus (voiced by Daws Butler impersonating Joe E. Brown; Butler uses an identical voice for Lippy the Lion) and his diminutive sidekick So-So the monkey (voiced by Don Messick). Peter is big, purple, and friendly, dressed in a safari jacket and hat. Episodes generally consist of Peter and So-So exploring the world in his hot air balloon, which is capable of time travel at the spin of a dial. When faced with a precarious situation, Peter uses his Hippo Hurricane Howler to blow away his opponents.

Breezly and Sneezly
A polar bear named Breezly Bruin (voiced by Howard Morris) and his friend Sneezly Seal (voiced by Mel Blanc) use various schemes to break into an army camp in the frozen north, while trying to stay one step ahead of the camp's leader Colonel Fuzzby (voiced by John Stephenson).

Yippee, Yappee and Yahooey
Three dogs named Yippee (voiced by Doug Young), Yappee (voiced by Hal Smith), and Yahooey (voiced by Daws Butler impersonating Jerry Lewis) aka The Goofy Guards, work for the King (voiced by Hal Smith), a short, complaining ruler who is often on the receiving end of their antics. The trio's plumed hats and swords are reminiscent of The Three Musketeers.
