From the ABC Saturday Superstar Movie is a backdoor pilot for the following year's Yogi's Gang.
Yogi's Ark Lark brings Yogi Bear and Boo Boo together with some of their fellow Hanna-Barbera funny animal stars, such as Huckleberry Hound, Squiddly Diddly, Magilla Gorilla, Lippy the Lion & Hardy Har Har, Snagglepuss, Quick Draw McGraw, Top Cat, and more. In a modern day, environmentally-charged spin on the Biblical story of Noah's Ark, Yogi and pals team with Captain Noah to raise awareness of the then-prevalent issues of littering and pollution, issues that would be explored again 20 years later on Captain Planet. While Yogi (Daws Butler) had a rep for being a thief, he wasn't a litterbug.
The idea behind Ark Lark was to bring back Yogi, Huck, et al, and introduce them to a new generation of viewers. Their classic shorts would soon return in syndication as a by-product of this film and the subsequent Yogi's Gang, even though the series lasted just 1 season. As we've noted previously in reviewing Gang, the series would later return, with episodes chopped up into two parts---and in this particular case, four, as it was rerun on Gang as a two-part story---in order to fit an additional segment or two into Fred Flintstone & Friends.
Despite the cancellation, interest in Yogi and his growing supporting cast was such that Yogi, Huck, Snagglepuss, and others would resurface again and again in later years, including the mid-80's series, Yogi's Treasure Hunt, which recast Top Cat (Arnold Stang) in more of a leadership role that was never really explained.
