The morning after the birthday fete, as the Wizard and Dorothy were walking in the grounds of the palace, Ozma came out and joined them, saying:  
"I want to hear more of your adventures in the Forest of Gugu, and how you were able to get those dear little monkeys to use in Dorothy's Surprise Cake."
 
So they sat down on a marble bench near to the Fountain of the Water of Oblivion, and between them Dorothy and the Wizard related their adventures.
 
"I was dreadfully fussy while I was a woolly lamb," said Dorothy, "for it didn't feel good, a bit. And I wasn't quite sure, you know, that I'd ever get to be a girl again."
 
"You might have been a woolly lamb yet, if I hadn't happened to have discovered that Magic Transformation Word," declared the Wizard.
 
"But what became of the walnut and the hickory-nut into which you transformed those dreadful beast magicians?" inquired Ozma.
 
"Why, I'd almost forgotten them," was the reply; "but I believe they are still here in my pocket."
 
Then he searched in his pockets and brought out the two nuts and showed them to her.
 
Ozma regarded them thoughtfully.
 
"It isn't right to leave any living creatures in such helpless forms," said she. "I think, Wizard, you ought to transform them into their natural shapes again."
 
"But I don't know what their natural shapes are," he objected, "for of course the forms of mixed animals which they had assumed were not natural to them. And you must not forget, Ozma, that their natures were cruel and mischievous, so if I bring them back to life they might cause us a great deal of trouble."
 
"Nevertheless," said the Ruler of Oz, "we must free them from their present enchantments. When you restore them to their natural forms we will discover who they really are, and surely we need not fear any two people, even though they prove to be magicians and our enemies."
 
"I am not so sure of that," protested the Wizard, with a shake of his bald head. "The one bit of magic I robbed them of—which was the Word of Transformation—is so simple, yet so powerful, that neither Glinda nor I can equal it. It isn't all in the word, you know, it's the way the word is pronounced. So if the two strange magicians have other magic of the same sort, they might prove very dangerous to us, if we liberated them."
 
"I've an idea!" exclaimed Dorothy. "I'm no wizard, and no fairy, but if you do as I say, we needn't fear these people at all."
 
"What is your thought, my dear?" asked Ozma.
 
"Well," replied the girl, "here is this Fountain of the Water of Oblivion, and that's what put the notion into my head. When the Wizard speaks that ter'ble word that will change 'em back to their real forms, he can make 'em dreadful thirsty, too, and we'll put a cup right here by the fountain, so it'll be handy. Then they'll drink the water and forget all the magic they ever knew—and everything else, too."
 
"That's not a bad idea," said the Wizard, looking at Dorothy approvingly.
 
"It's a very GOOD idea," declared Ozma. "Run for a cup, Dorothy."
 
So Dorothy ran to get a cup, and while she was gone the Wizard said:
 
"I don't know whether the real forms of these magicians are those of men or beasts. If they're beasts, they would not drink from a cup but might attack us at once and drink afterward. So it might be safer for us to have the Cowardly Lion and the Hungry Tiger here to protect us if necessary."
 
Ozma drew out a silver whistle which was attached to a slender gold chain and blew upon the whistle two shrill blasts. The sound, though not harsh, was very penetrating, and as soon as it reached the ears of the Cowardly Lion and the Hungry Tiger, the two huge beasts quickly came bounding toward them. Ozma explained to them what the Wizard was about to do, and told them to keep quiet unless danger threatened. So the two powerful guardians of the Ruler of Oz crouched beside the fountain and waited.
 
Dorothy returned and set the cup on the edge of the fountain. Then the Wizard placed the hickory-nut beside the fountain and said in a solemn voice:
 
"I want you to resume your natural form, and to be very thirsty—Pyrzqxgl!"
 
In an instant there appeared, in the place of the hickory-nut, the form of Kiki Aru, the Hyup boy. He seemed bewildered, at first, as if trying to remember what had happened to him and why he was in this strange place. But he was facing the fountain, and the bubbling water reminded him that he was thirsty. Without noticing Ozma, the Wizard and Dorothy, who were behind him, he picked up the cup, filled it with the Water of Oblivion, and drank it to the last drop.
 
He was now no longer thirsty, but he felt more bewildered than ever, for now he could remember nothing ............
