The four travelers ring the bell at the Gate. The Guardian is surprised to see them. "You're back from the Land of the Winkies!" he says. "Yes, we are," Dorothy says. "We want to see the Great Wizard!" The Guardian takes them to the Palace of Oz. They have a good dinner and go to bed early.

The next morning, the Wizard keeps his word and helps them. The scarecrow goes to see Oz first. "Do you have my brain?" he asks. "Yes, I do. Come here and sit down, please. I will give you a real head," Oz answers. Oz takes out a few bottles of potion. He pours them on the scarecrow's head. He also waves his magic wand and says a few spells. After a burst of light, the scarecrow says, "Thank you very much, I feel quite intelligent now." Then it's the Tin Woodman's turn. "Do you have my heart?" "Yes, I do. Come here and sit down, please," Oz says. He waves his wand again and recites some different spells. Then, a beautiful red heart is in the Tin Woodman's body. "It's visible! So marvelous! Thank you, Oz," the Tin Woodman says. Next, the Lion enters. "Do you have some courage for me?" he asks. "Yes, I do," Oz says. Oz conjures a bottle of potion with his wand. It's colorful and looks magical! The Lion drinks it in one gulp and says delightfully, "Wow! I feel very, very brave now! Thanks, Oz."

Finally, Dorothy enters the Throne Room. "Can you send me back to Kansas?" she asks. "I'm sorry, but I don't know the spells. You must go and see Glinda, the Witch of the South," Oz says. "She rules the land of the Quadlings. The Quadlings believe she is good. She's kind to everyone. She's also young and beautiful. I'm glad to send you there." "Thank you very much," Dorothy says. Therefore, Oz waves his wand and recites some spells. The four travelers are transported to the land of Quadlings with a flash of light
