George and Harold climb into their time-traveling Purple Potty and emerge in the strangest place they've ever seen. The teachers smile and act kindly. The cafeteria food tastes amazing. Principal Krupp finds their jokes funny instead of punishing them. This backward world feels deeply wrong to the boys who know how things should work. Their confusion turns to horror when evil versions of themselves appear and capture Crackers the pterodactyl and Sulu the Bionic Hamster. These twisted doubles look exactly like George and Harold but act with pure malice. The real boys must rescue their beloved pets from their own dark reflections. George and Harold face an impossible challenge. How do you defeat enemies who know all your moves because they are you? The battle against their evil twins pushes them to their limits. They might need their underwear-clad superhero to rescue them from this predicament. The boys discover that sometimes your worst enemy wears your own face.
