“ Even the Bear King was now puzzled by the contradictory statements of his oracle.
"Where is she?" asked the King.
"Here, among you," answered the little Pink Bear.
"Well," said Dorothy, "this beats me entirely! I guess the little Pink Bear has gone crazy."
"Perhaps," called Scraps, who was rapidly turning "cartwheels" all around the perplexed group, "Ozma is invisible."
"Of course!" cried Betsy. That would account for it."
"Well, I've noticed that people can speak, even when they've been made invisible," said the Wizard. ”

“ All that first day after the union of the two parties, our friends marched steadily toward the wicker castle of Ugu the Shoemaker. When night came, they camped in a little grove and passed a pleasant evening together, although some of them were worried because Button-Bright was still lost.
"Perhaps," said Toto as the animals lay grouped together for the night, "this Shoemaker who stole my growl and who stole Ozma has also stolen Button-Bright."
"How do you know that the Shoemaker stole your growl?" demanded the Woozy. ”

“ Button-Bright laughed.
"You're getting rattled, Dorothy," he replied. "Nothing ever enchants me. If I were Ozma, do you think I'd have tumbled into that hole?"
"Anyhow," said the Wizard, "Ozma would never try to deceive her friends or prevent them from recognizing her in whatever form she happened to be. The puzzle is still a puzzle, so let us go on to the wicker castle and question the magician himself. Since it was he who stole our Ozma, Ugu is the one who must tell us where to find her. ”
