Well, its the beginning of spring and that means only 1 thing for Dave...SPRING CLEANING!! The rest of the family run away from the castle to avoid cleaning. Dave uses Dusty, the magical cleaning broom and sweeps the castle. After months of cleaning, Dave is in need of one more thing, Castle Polish. Oswidge finds a coupon for Castle Polish at 1/2 price, so they go to the Fortress of Cleanliness, only to find that the Fortress of Cleanliness is the Fortress of Uncleanliness and is a trap set by The Dark Lord Chuckles The Silly Piggy and are forced to clean for him. The family wants to leave, but Dave is too obsessed about cleaning and doesn't want to leave...
