The Decades channel had HR Puffinstuf on for a while about a year ago, along with the original Land of the Lost, which I think may qualify as the strangest kid's show ever if not just the strangest period, on Saturday nights, but unfortunately took them away again. I can't picture Lidsville in my mind although the character on the left seems VERY familiar.
Lidsville was a short lived Sid And Marty Kroft production starring Billie Hayes (Witchiepoo), Butch Patrick (Eddie Munster) and Charles Nelson Reilly. I haven't seen it since it ran originally
