No doubt Pepe's gonna be in there. I think there's a chance Sal will too, but I fear that Johnny may be cut out since Sal's been making many solo appearances lately. There's a good chance Bobo will be back too since it seems that Sal, Pepe, Bobo and Clifford are the 4 members of the Muppets Tonight cast to be around the most. Bean could most likely reappear too.
Some of these requests are pretty odd. First of all, I didn't like Clueless, to me he's like the love child of Zoot and Andy Pig. If we have to use a MTI character, how about Jaques Roach? He's been around before and he can come back, just like a real roach.
Digit? Who performed Digit? Is it even possible to bring him back? And wasn't his look too much of a contrast between Kermit and Gonzo even during JHH?
As much as we'd like to see it happen, ain't gonna be no Fraggles.
Dr. Phil? I dunno what the deal was but it seems that Brian won't be around to do many characters.
Ultimately, I think the reason they keep adding new members to the cast is tht the available list of puppeteers is always changing around. We probably never noticed it from watching reruns when at the time the latest cast members were Steve Whitmire, Bill Baretta and Brian Henson, but by the time this series rolls around they'll have a couple new puppeteers which will have to resort to playing new roles.
