Thinking about the Chip appearance again (it has barely left my mind since the trailer was online), I feel like now would be a good time for Chip to get a Weekly Muppet Wednesday article on The Muppet Mindset. That doesn't mean that he'll be next, but Uncle Deadley's WMW was the first to come after it was announced that he'd be in The Muppets (the 2011 film), and the Annie Sue article came out shortly after it was announced she'd be in Muppets Most Wanted.
The small mix of obscure characters for that scene is interesting. We have Chip, who may or may not be very recognzable (he was seen in the background a lot on Muppets Tonight and MFS). There's the happy creature from "Hugga Wugga", which seems like a popular sketch from The Muppet Show, and until Muppets Most Wanted he had only been used once (I wonder if that's the same puppet as the original or if it was rebuilt). Then there's Beautiful Day Monster, who has been used in a few recent productions. Finally, there's Cynthia Rose, from the "Starfish and Coffee" number. She seems to be the most obscure one there. I had seen the number, but when I first saw the trailer, I didn't quite recognize her (I was thinking she was one of the pirates from MTI), and there's a number of Muppet Central, Tough Pigs, and Facebook comments from people who didn't recognize that character, either. And even after I found the characters name, I kept forgetting what it was. I guess it helps that most of the Prince episode is not on YouTube (though the whole thing is, or at least was a few months ago, on Daily Motion).
Denise is sort of the only new character we know of so far. I wonder how far The Muppet Mindset will wait before putting up articles on characters introduced on this show. It doesn't really matter, and I'm not in charge of the site, but when it comes to possible WMW articles for that site, I feel users should probably wait at least a season after they're introduced, so there'll be more to write about. We don't know how many new characters will be introduced in the first season.
