Harry is looking for his building blocks, but can't seem to find them anywhere in his room. His Mom says that his room is a mess and that she's going out to the grocery store, but she wants to see it neat and tidy by the time she comes back. Harry doesn't like this idea at all, but he loves it when Taury tells him that there's a no-cleaning rule in Dino World. He just made that rule up and so Harry and the dinosaurs test it out. They soon create a colossal mess and then Harry decides to dump the stuff from his room in Dino World. Patsy warns that it will all end in tears, but Harry goes ahead with the plan anyway. Pretty soon, Dino World has turned into garbage world --- it's a garbage emergency!
