Besides Secret Squirrel, there was also two other cartoons on the 1965 NBC version.
SQUIDDLEY DIDDLEY: A squid (voice of Paul Frees) who lives in Bubbleland, ran by Chief Wenchley. Squiddley would always venture into the outside world, just like the Wally Gator cartoons.
But my favorite...
WINSOME WITCH: A motherly-type good witch (Jean Vander Pyl) has adventures helping out people & sometimes righting wrongs by using her witchcraft!
I loved it when she waved her magic wand & saying the magic words, "Ippedity, Pippedity, POW!" (Jet Screamer cue theme)!
Winsome made a comeback in 1990 as the driver of the sonic broom on "Fender Bender 500", car #13.
