We never see Nanny’s face in the Muppet Babies series, but her characteristic green and white striped stockings and purple sneakers always stood out. Though we assume she’s human, it’s also quite possible she could be a Muppet as well.
Jareth (David Bowie) is the Goblin King who is summoned by Sarah to take her infant brother away. He gives Sarah a chance to get her brother back if she can make it through The Labyrinth. Along the way he distracts her with song and dance but it’s his choice of pants that distracts viewers.
