When I was a kid, I owned the Cookie Monster, Oscar and Big Bird puppets (though I'd hardly consider the Big Bird doll a puppet. There was a small lever that barely moved his mouth). My best friend from the 3rd grade owned the Grover puppet, and my girlfriend's grandma once had the Bert puppet in her possession. Grover, Ernie, Bert and Big Bird were very, very hard puppets (Big Bird's face was a lethal weapon), but the other one's were very soft, and Cookie had a feature where you could stuff things into his mouth and through his body. I also owned an early Count puppet which came with a plastic arm wire. Pretty cool, except the toy makers didn't have a very good handle on his hair. He ultimately looked like he had a bad perm.
