The dragon and the wild cat descended onto the battlefield, roaring. The dragon cried, "You iron beasts have conquered the world, but don't get your hopes up too high. You will be destroyed and shattered, and we will once again rule the earth alone!"
The cat climbed down from the dragon's back, searching for the flying eyes. She placed her nose on the ground, sniffing them, and stopped at the last eye, about to close it. The cat looked at it, tears streaming down her face, crying and meowing. "My power is shattered!" she exclaimed.
She stared into the eye and saw the image of the money, Kabeli, shimmering in its center. The cat realized that the money had descended from its hiding place and was walking on top of it. She quickly jumped up to the dragon's ear, saying, "The castle's money has leaked! You're sitting on top of it!"
The dragon roared, "Have you seen the castle keys?" The cat replied, "Perhaps they're under the money." The dragon asked, "Do you mean the boy is buried under it?" The cat answered, "Perhaps." The dragon ordered, "Go collect the money!"
Behind them, the boy, Sayli, was gathering the money into bags and placing them beside the dragon, while a frog filled each bag handed to it. The frog asked, "Why are you doing this, boy?" Sayli replied, "I think monsters love money. I'll make them think about it."
The cat saw the bags and rolled them onto the dragon's back, thinking to herself, "I've become so weak. I used to enter Kabel's house effortlessly, take his money, and fly off to the castle. Now I suffer, cursing this poisonous, heavy money."
