This is definitely cool news, and I'm glad to see a company like Palisades get this license. It makes sense with the amazing work they have done on the Muppets line, and from what I have read, they seem to work with collectors pretty well. I doubt the Mrs. will let these enter the house, although I wouldn't mind having a Cookie Monster. The Super Grover looks cool too, I remember being quite a fan when I was little. It will be tough to avoid this line, at least the "main" characters - Big Bird, Bert/Ernie, Cookie, Oscar, Grover, Snuffy, etc.
Also, a little more info on Super Grover (and the line) at their Daily Bit
