Well, it's basically about two twins that grow up together, and one of them (the Muppet one) never grows, while his brother does. He then learns of The Muppets, and he becomes their biggest fan, and he always remained loyal to them. When he and his brother are full grown, his brother finds a woman that he fell in love with, and they decide to go on a trip, and the other brother is included since there's going to be a tour of the old Muppet's place. They find out that it's going to be destroyed, and they work to get the old Muppet team back together for one last show to raise enough money to save the place. All in all, it's pretty good for a remake.
