Muppet Babies - Showtime Classic ViewMaster - 3 reels, 21 3D Images

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 becomes "real" to the babies, such as finding themselves aboard a pirate ship or in the land of Oz. When the pretend game becomes too perilous, or when an interruption occurs (often in the form of Nanny checking in or the imaginary game straying too far from its original premise), the scene dissolves and they find themselves in the nursery once more.
