Then the Tiger lay down again to sleep, but the monkeys soon discovered that the bending of the bars would allow them to squeeze through. They did not leave the cage, however, but after whispering together they let their tails stick out and all remained quiet. Presently the Glass Cat stole near the cage again and gave a yank to one of the tails. Instantly the monkeys leaped through the bars, one after another, and although they were so small the entire dozen of them surrounded the Glass Cat and clung to her claws and tail and ears and made her a prisoner. Then they forced her out of the tent and down to the banks of the stream. The monkeys had noticed that these banks were covered with thick, slimy mud of a dark blue color, and when they had taken the Cat to the stream, they smeared this mud all over the glass body of the cat, filling the creature's ears and eyes with it, so that she could neither see nor hear. She was no longer transparent and so thick was the mud upon her that no one could see her pink brains or her ruby heart.
In this condition they led the pussy back to the tent and then got inside their cage again.
By morning the mud had dried hard on the Glass Cat and it was a dull blue color throughout. Dorothy and Trot were horrified, but the Wizard shook his head and said it served the Glass Cat right for teasing the monkeys.
Cap'n Bill, with his strong hands, soon bent the golden wires of the monkeys' cage into the proper position and then he asked the Wizard if he should wash the Glass Cat in the water of the brook.
"Not just yet," answered the Wizard. "The Cat deserves to be punished, so I think I'll leave that blue mud—which is as bad as paint—upon her body until she gets to the Emerald City. The silly creature is so vain that she will be greatly shamed when the Oz people see her in this condition, and perhaps she'll take the lesson to heart and leave the monkeys alone hereafter."
However, the Glass Cat could not see or hear, and to avoid carrying her on the journey the Wizard picked the mud out of her eyes and ears and Dorothy dampened her handkerchief and washed both the eyes and ears clean.
As soon as she could speak the Glass Cat asked indignantly: "Aren't you going to punish those monkeys for playing such a trick on me?"
"No," answered the Wizard. "You played a trick on them by pulling their tails, so this is only tit-for-tat, and I'm glad the monkeys had their revenge."
He wouldn't allow the Glass Cat to go near the water, to wash herself, but made her follow them when they resumed their journey toward the Emerald City.
"This is only part of your punishment," said the Wizard, severely. "Ozma will laugh at you, when we get to her palace, and so will the Scarecrow, and the Tin Woodman, and Tik-Tok, and the Shaggy Man, and Button-Bright, and the Patchwork Girl, and—"
