I always loved Skeeter, but that is besides the point. Though I liked her better when Frank Welker took over her voice since I find Howie Mandell annoying.
For a while it really looked like they were trying to make her a regular Muppet. Skeeter was a featured character in Muppet Kids (which never made it to TV), the McDonald's toys for that set and she was also featured in a set of books with the rest of the gang. I have always wondered if all those products hadn't come out right before Henson's death if she wouldn't have become a bigger deal.
The Muppets now a days are definately in need of some new (and more importantly) strong female characters and Miss Piggy can't hold the entire weight of that.
I would love to see Skeeter come back. I have always thought Karen Prell would be perfect for her.
