Does anyone remember old HBO children's special?

I remember a show when I was little that came on HBO only once in the mid 80's. It was a guy in a room with oversized furniture bc he was a "kid" and he jumped around sang and the name of the show was a song he sang. I think it was about a monster and I can only remember it kinda went like "wildwildwiggle.. something something something..with you". This is driving me CRAZY that I can't remember this special! I'm not kidding, I'm honestly loosing sleep!!!! Does anyone remember this? Or another special that was a cartoon where all the characters were flowers. The prettiest and I guess lead character was a white rose. It isn't Rose Petal Place bc I bought that VHS thinking that was it and it isn't. Any possible answers? Thanks a bunch!
