chunk: In the city of Herku, Dorothy and the Wizard's party are greeted by the emaciated but jovial Czarover of Herku, who has invented a pure energy compound called zosozo that can make his people strong enough to keep giants as slaves. The Czarover offers them six doses to use in their travels and casually reveals that Ugu the Shoemaker came from Herku. Ugu found magic books in his attic one day because he was descended from the greatest enchanter ever known and learned over time to do a great many magical things. The Shoemaker has since moved from Herku and built a castle high in the mountains. This clue leads Dorothy and the Wizard to think that Ugu might be behind all the recent thefts of magic and the ruler of Oz. They proceed from Herku toward the castle and meet with the Frogman, Cayke the Cookie Cook, and the Lavender Bear the stuffed bear who rules Bear Center. Lavender Bear carries the Little Pink Bear a small wind-up toy that can answer any question about the past put to it.
