Obscurity factor: 5
Penelope Pitstop (Janet Waldo) is a fabulously wealthy heiress and race car driver. Her estate is administered by Sylvester Sneekly (Lynde) who, unbeknownst to her is also her arch nemesis The Hooded Claw. Each episode features Penelope being targeted by Sneekly with a series of dastardly traps and torments. Riding to her rescue are the Ant Hill Gang, a septet of pint sized gangster types and their heroic car, Chugaboom.
This animated series, based on the silent film series, The Perils of Pauline, was produced by Hanna/Barbara and lasted one season. There are 17 episodes. Above is part one of Jungle Jeopardy, in which we find Penelope at Sneekly's mercy on a tropical island. It's been uploaded by nayeem03. The complete series is available on DVD and several other episodes are also available on YouTube.
