Barbapapa:
Barbapapa was a cartoon that ran in the early-mid 70's. It was about a hippie blob-family that could morph and change their shapes. They lived in sort of a habitrail-type commune. I don't remember if this was on Saturday mornings or Sunday. The show also featured two human children whom I'd forgotten about until I saw the above pic for the first time. I don't really remember any episodes. It was kind of a bland, non-eventful cartoon..
