This show had a lot of imagination in it, much like some episodes of Rugrats today i guess (except better) Coupled with the immensely brilliant characters of the muppets you have one hell of a cartoon.
The muppet babies mainly told each other stories and re-enacted famous stories/films/plays etc, it was fun and innocent and much better than watching the teletubbies and the tweenies! Much more can be taught by watching a baby frog and a baby pig re-enact romeo and julliet than by watching a fat purple alien ponse around with his handbag going "et oooh"
If you are a new parent, forget the bull you find on television now. Go on the internet and download this, Thomas the Tank Engine (Ringo Star only) and other old classics like that. They didn't do you any harm, but your kids stand no chance with todays crap!
