Amy managed to sneak a Sesame Street character (Wolfgang the Seal) and the LaChoy dragon in a couple times. Shelli managed to go off copyright completely in cases (though, altered to a parody extent). I gotta take these things all out and flip through them to check that other stuff out.
Really a shame no one tried shoving Digit in the background. I wonder if the JHH characters were just a source of confusion... I swear they were owened by Disney too.
If I was the artist I woulda been sneaking in all sorts of cameos, even if it was just vague sillohette. I woulda put in Digit, Ploobis, Scred, Leon, etc
Ha, I remember La Choy dragon! That was so random for her to put that in there, even most diehard muppet fans may not know about that. Im all about for artists subverting copyright.
I personally do not make distinctions legality wise between the Muppets(tm), Sesame Street, Fraggle Rock, Bear in the Big Blue House, Hoobs, Mopatop, foreign Sesame, Pajanimals, Henson Alternative brand...to me it's all Muppets in my book
