Bradley has worked hard to prepare for his class speech. However, the class bully steals his backpack that contains the speech and throws it into the creek. While searching through the muck of the polluted creek, Bradley finds an interesting lump of something that he takes home for his weirdo collection. It turns out to be magic; whatever you are thinking of, it will make you say. When the class bully snatches it, it makes him confess all the nasty things he has done, and Brad gets a new souvenir.
