Muppets/Bear crossover

[Gusworld]

In the Bear In The Big Blue House episode Rockin' Rocko, which I rewatched recently, the gang go to see a movie called 'Hare' (a sendup of the 1960s musical classic Hair, a point presumably lost on most of the target toddler viewers!) Anyway, the hare character looked extremely like a redressed version of Bean Bunny, providing an interesting example of a Bear/Muppets crossover of sorts. In fact, I can't remember this occurring in the series elsewhere; can anyone remember others?

Cheers
