"In that case, I've solved the riddle," cried Scraps, dancing with glee. "Those fence-boards are made of wood, and if the Woozy stands close to the fence and lets his eyes flash fire, they might set fire to the fence and burn it up. Then he could walk away with us easily, being free."

"Ah, I have never thought of that plan, or I would have been free long ago," said the Woozy. "But I cannot flash fire from my eyes unless I am very angry."

"Can't you get angry 'bout something, please?" asked Ojo.

"I'll try. You just say 'Krizzle-Kroo' to me."

"Will that make you angry?" inquired the boy.

"Terribly angry."

"What does it mean?" asked Scraps.

"I don't know; that's what makes me so angry," replied the Woozy.

He then stood close to the fence, with his head near one of the boards, and Scraps called out "Krizzle-Kroo!" Then Ojo said "Krizzle-Kroo!" and the Glass Cat said "Krizzle-Kroo!" The Woozy began to tremble with anger and small sparks darted from his eyes. Seeing this, they all cried "Krizzle-Kroo!" together, and that made the beast's eyes flash fire so fiercely that the fence-board caught the sparks and began to smoke. Then it burst into flame, and the Woozy stepped back and said triumphantly:

"Aha! That did the business, all right. It was a happy thought for you to yell all together, for that made me as angry as I have ever been. Fine sparks, weren't they?"
