order to warn Ozma about Ruggedo's plans. Meanwhile, using the power of the repaired cloak, Ruggedo becomes invisible and teleports to the Emerald City, where he causes some mischief before Peter arrives. Still invisible, Ruggedo steals the magic belt. He is about to use its powers to teleport Ozma and her friends to the bottom of the ocean, but Peter overcomes him by throwing a "silence stone", one of the treasures he had taken from the sunken pirate ship, at Ruggedo's head, which robs Ruggedo of the power of speech. Since the magic belt only responds to spoken commands, this renders Ruggedo harmless, and the Wizard of Oz makes him visible again. Ozma makes Peter a Prince of Oz, but the boy chooses to return to Philadelphia; he can't let down his team.
