S2·E11 The Muppet Museum of Art

The Muppet Babies are about to go to the art museum when Skeeter gets hurt by one of Piggy's pink skates. Before everyone could notice the skate, Piggy replaces her skate with Gonzo's in the scene of the accident so he could take the blame. Since they can't go to the art museum now, the muppets decide to bring the art museum to the nursery by creating their own works of art. Gonzo paints portraits of Piggy, but her roller skate mysteriously appears in Gonzo's paintings. Freaked out by this, Piggy attempts to keep Gonzo's paintings out of sight. The muppets then show their artwork to Nanny and an injured Skeeter. When Gonzo shows to everyone a beautiful picture of Piggy, Piggy finally confesses to framing Gonzo and apologizes.
