his series was the third segment on The Peter Potamus Show, the other segments being Peter Potamus and Breezly & Sneezly (later swapped with Ricochet Rabbit). Each segment was 6 minutes 45 seconds in length.

Yippee, Yappee and Yahooey were three bumbling, Musketeer-like dogs who loyally served their king as palace guards. Yippee was the tallest and had purple fur, Yappee was medium height with white fur, and Yahooey was the shortest, with orange fur. Whenever the king summoned them he had to duck for cover because his "three goofy guards" were prone to making flamboyant, crash entrances. Their incompetence caused the king a considerable amount of grief, but apparently never enough to replace them.

Unlike the majority of Hanna-Barbera's anthropomorphic, animal characters that moved on to other series once their own had ended, Yippee, Yappee and Yahooey quietly faded into obscurity after 23 episodes.
