Uncle Statler and Waldorf bring over a train set similar to the trains used in the building of the Transcontinental Railroad, so the babies join them in recreating said railroad right in their own home.
The babies overhear the news mention a ski-mask burglar called "Mad Dog Marvin" has escaped from jail and they think he's heading their way; as Nanny tries to get the house locked up before a storm hits.
Piggy's Alice in Wonderland book is due back at the library but she can't find it; Gonzo thinks goblins took it and the muppets try to make a new one before Nanny comes for it.
The kids prepare a surprise birthday party for Statler and Waldorf but can't agree on what the surprise should be. One idea is Star Tours, a real motion simulator attraction at Disney theme parks based on Star Wars.
