I think you have to think of this Kermit as a manequin to show off the clothes. I think the big problem is that they have him sitting. The coat would look much better if he was standing, but I'm pretty sure there isn't room in the display case for him to stand. And I think he's going to have pants, too. There just wasn't enough time to make them.
None of Rizzo's colors are final. This is, after all, a prototype that was hand dyed. They will be matched to the real colors when he goes into production.
I can't really describe how big Piggy's head is, except to say it's actual size. Maybe if I have time this morning, I'll post another picture of her next to Kermit (that's where she is), but I actually have to work this morning before I can go to the Con, so I may not have time to post again until late tonight.
To Muppetcaper: There was lots of Star Wars stuff in the booth, but this is Muppet Central. I'm sure some of the Star Wars fan sites will post pix of that cool stuff. If you don't see them anywhere else, post a message in this thread (my PM box is full) and I'll PM you a couple of pix before the Con is over.
Edit: Sorry. It was muppetguy that asked about the Star Wars stuff, but I know Muppetcaper is also interested in that line.
