I still have the Fisher-Price Rowlf puppet that the Easter Bunny brought me (along with the usual array of chocolate eggs) in 1981, when I was eight...He accompanied me and my wife, and the Christian youth group we run, to a December showing of The Muppets and has brought me much joy over the years.
I have absolutely no intention of parting with him. He's still awesome.
Fisher-Price also marketed a great Animal puppet (with INCREDIBLE eyes and teeth) at the same time and that's one of the few things I'd really love to add to my Muppet collection. Well, that and some Walter stuff.
