There are calendars of the 1970s that have less 1970s in them than this cartoon.

This started out rough, but it's honestly pretty good. Incredibly misleading VHS cover art, but that's to be expected of these things I guess. Outlandish art style wasn't really for me, but I was able to look past it. This is very 70's, in that it promotes being yourself and quite blatantly discusses the idea that those who often claim to be the most virtuous are actually the worst among us. The witch is brilliantly voiced by Gilda Radner, & her dress transformation at the end rocks.
