So far, of the books I've located there are more to find, I still have not found Nanny's face. But I know I've seen it somewhere. The search continues.
My mother bought my youngest a stuffed Piggy for Christmas and it came with a one episode DVD of Muppet Babies. Remember the one when it was raining and the babies had to play inside with the activity book?
I enjoyed it more than the kids did!
