It's funny. Perhaps the most recurring character to appear on ABC during the late 70's was Bigfoot. The producers of The Six Million Dollar Man utilized Bigfoot in a couple of episodes of that series, and, then, there was the heroic version starring in the Kroffts' Bigfoot & Wildboy. In 1980, it was Hanna-Barbera's turn, and, oh, did they go overboard!
Not only do the Super Friends encounter one Bigfoot, but a whole tribe of them in this 1980 short.
It's too bad Walking Eagle was never heard from again. The writers never even considered the prospect of having Apache Chief play matchmaker and arrange a date with Jayna........
