I don't see why every shirt has to be either Kermit or (more likely) Animal. Animal is like the Elmo of the Muppets, if only for the fact he's got too much of a presence in the merchandise. I guess we'd tend to see more Muppet Shirts in other places if there wasn't so many dang Angry Birds shirts everywhere. Really... it's like ALL they have in stores anymore is Angry birds shirts.
YES, you have hit the nail on the head, my friend. On both accounts. I like Animal and all, but I find it really irritating that he's EVERYWHERE in the merch. I'd peg him below Fozzie or Gonzo in terms of "Main Character", but anytime it's 3 characters it's almost always Kermit, Piggy, and Animal. And i'd flip for anything of Swedish Chef. AND I don't think it's been mentioned but on the UK DisneyStore site every plush has a "Group Pic" of all of them, and in it is a plush Swedish Chef. HOPEFULLY he got pulled and is still planned to be released.
On a semi-related note, they do sell Statler and Waldorf shirts at Disney Parks. You can't go wrong with Kermit shirts, but it would be great to see more with Fozzie and Gonzo, they seem to be getting the short end of the T-Shirt stick.
And I won't even start on the Angry Birds topic, but it is WAY overmerchandised for a graphic re-design of a "Time waster" game that's been around for around 10 years.
