I mentioned this in another thread, but when it comes to characters who don't appear on the show, whether the writers can't figure out a way to work them in, or if Bill Prady doesn't think they fit the shows format, it would be great if there would be some viral videos starring them.
But I also wonder how many puppets are near the studio. I've read that Puppet Heap is located in New Jersey, and this (along with many other Muppet productions) is being filmed in Hollywood. I wonder if there's special storage for this kind of thing, or if Puppet Heap has an LA branch. I'd be surprised if every Muppet was sent there, and I wonder if they would want to go through the trouble of delivering puppets to the studio if they usually aren't on the show. Then again, The Jim Henson Company has had works in LA (before opening an LA office, though the company hadn't done too many LA productions), Toronto, and England (before forming the creature shop), and it seems like delivering the puppets wasn't a problem then (when The Muppet Show was on the air, did they send every non-Sesame, non-Gorch, non-"early Henson" puppet to the studio so they could use any character they suddenly wanted to use?).
