The Muppet Babies live in a large nursery watched over by Nanny, who is seen only from the shoulders down. The babies' imaginary games transition from the nursery into scenes that become "real" to the babies, such as outer space and the past. Often, these fantasies have the babies interact with live-action backgrounds, old films and photos, engravings, and hand-drawn backgrounds.The babies used their imaginations to have their own adventures based on everyday things and toys around them. They also use their imaginations to solve a problem, but occasionally their imaginations run away with them. In post-credits scenes, the babies are doing something related to the episode's plot, either in their imaginations or reality, sometimes with an appearance by Nanny. Their activities (mostly Gonzo's) are interrupted by Animal who crashes the scene in a comedic way and calls "Go bye-bye!"
