I like Target too, although I am angry at them for dropping the Muppet line. Unfortunately, they came in at the wrong time. Had they started with either series 3 or series 5 and come out with the figures at the same time as other stores, they would have been more successful. I believe that in terms of the casual shoppers, Series 4 was the weakest series. (Don't get me wrong, I love my Series four figures!)
Oh, wait! I just realized that this thread is about Mini Muppets! Target did not ever sell the Mini Muppets so they cant be blamed for their lack of popularity. I guess there is just not quite as much demand for the Minis from fans like us.
