The four travelers ring the bell at the Gate, surprising the Guardian who sees them. "You're back from the Land of the Winkies!" he exclaims. "Yes, we are," Dorothy replies. "We want to see the Great Wizard!" The Guardian leads them to the Palace of Oz where they enjoy a delicious dinner and retire early to bed.

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

Lastly, Dorothy enters the Throne Room. "Can you send me back to Kansas?" she inquires. "I'm sorry, but I don't know the spells. You must go and see Glinda, the Witch of the South," Oz explains. "She rules the land of the Quadlings, and they believe she is good. She is kind to everyone and is also young and beautiful. I am happy to send you there." "Thank you very much," Dorothy expresses her gratitude. Thus, Oz waves his wand and recites some spells. In a flash of light, the four travelers are transported to the land of the Quadlings
