Does anybody know the name of this old Treehouse show?

I think this show stopped airing about 10 years ago, maybe less. It was like a 5 minute show. It had these two clowns, and I think they were sisters. One had dark curly hair, the other had blonde pigtails. I think they had names like Rosabelle, and something else. There was also this little purple monster, not sure what his name was, but he always sang this song about grapes? He had like fuzzy purple gray fur. Does anyone know the name of the show, the name of the clowns/monster, and maybe where I could find a video?
