Penelope Pitstop had a reason to be on DVD... I guess Charles in Charge may too... but definately Penelope Pitstop... after all, that's part of the original Wacky Races trilogy (which included Dasdardly and Muttley in their Flying Machines). And Wacky Races is a classic Hanna Barbera cartoon show.Really. They'll put friggin Penelope Pitstop and Charles in Charge on DVD, but not Muppet Babies?
The main thing stopping MB, we all know, is all those film copyrights. They could release a best of featuring the last 2 seasons which had only stock footage... but they weren't as good as the classic 84-87 episodes. I really think, while stilted and not as good as TMS would have done, Toei really gave the show a good look.
