"The Perils of Peter". Queen Ozma begins a tour of Oz to enlist the aid of her still-faithful subjects in raising an army to fight the Nome King. Peter remains a prisoner of that tyrant, and is sent to Mombi's torture chamber when it is discovered that Ozma has escaped. Eluding his guards, Peter becomes lost in the Emerald Castle and meets up with a young woman ensorcelled just as the Evil Kings had been. Freeing her, Peter discovers one of the most famous residents of Oz: Dorothy Gale of Kansas! Based on the L Frank Baum Wonderful Wizard of Oz books.
