MUPPET BABIES?! YUCK!!
I never could get into them, they were part of Piggy's imagination in TMTM, and do NOT fit into the chronology of The Muppets at all!! There is no way I can accept them.
The other thing that messes it all up for me is in the Muppet Family Christmas, after she IMAGINES them all as babies they pull out a FILM CLIP of them as Muppet Babies, and THAT throws out the whole chronology.
Sometimes, writers just don't keep their stories in mind.
