I'd also envision Muppet Baby versions of the Pajanimals, too!
I'd picture an episode where Nanny takes the babies to a farm, and the babies learning about animals, and it featuring the Pajanimals as babies, showing the babies all around their farm, and singing songs (like "La-La-Lullaby"), using imaginations, and also preventing Animal from wreaking havoc on everyone during their visit, but even with Sam's help, things don't go so well as planned. However, by the end of the episode, everyone gets along and the babies even invite Apollo, Squacky, Sweetpea Sue, and Cow Bella to their nursery for a sleep-over (with the baby Pajanimals singing "La-La-Lullaby" to put the babies to sleep for the night).
