Muppet Quilter has a point. If these accessories are too small for little kids to play with, they're going to go crazy if they can't have them. And yes, there are more kids who watch Sesame Street than toy collectors. Since the day I heard about these figures I've gone on here stating how these figures need to have the detail that the Muppet figures have and I hope they do, but with the points that have been made, the chances of the older crowd getting disappointed by these figures are very good.
As for making figures of the adults, I wouldn't suggest it, they won't sell. The kids aren't going to want them, they're going to want the Muppets, after all, that's who they tune in to see. Although, it would be ILL if they made a Mr. Hooper figure. Again, it unfortunately won't sell, they'll probably make it an exclusive for that reason, but it would be great to see him immortalized like that. BTW, can you believe it's been TWENTY YEARS since his death. Amazing.
