The Cat was sour-tempered and grumpy, at first, but before they had journeyed far, the crystal creature had discovered a fine amusement. The long tails of the monkeys were constantly sticking through the bars of their cage, and when they did, the Glass Cat would slyly seize the tails in her paws and pull them. That made the monkeys scream, and their screams pleased the Glass Cat immensely. Trot and Dorothy tried to stop this naughty amusement, but when they were not looking the Cat would pull the tails again, and the creature was so sly and quick that the monkeys could seldom escape. They scolded the Cat angrily and shook the bars of their cage, but they could not get out and the Cat only laughed at them.
After the party had left the forest and were on the plains of the Munchkin Country, it grew dark, and they were obliged to make camp for the night, choosing a pretty place beside a brook. By means of his magic the Wizard created three tents, pitched in a row on the grass and nicely fitted with all that was needful for the comfort of his comrades. The middle tent was for Dorothy and Trot, and had in it two cosy white beds and two chairs. Another tent, also with beds and chairs, was for the Wizard and Cap'n Bill, while the third tent was for the Hungry Tiger, the Cowardly Lion, the cage of Monkeys and the Glass Cat. Outside the tents the Wizard made a fire and placed over it a magic kettle from which he presently drew all sorts of nice things for their supper, smoking hot.
After they had eaten and talked together for a while under the twinkling stars, they all went to bed and the people were soon asleep. The Lion and the Tiger had almost fallen asleep, too, when they were roused by the screams of the monkeys, for the Glass Cat was pulling their tails again. Annoyed by the uproar, the Hungry Tiger cried: "Stop that racket!" and getting sight of the Glass Cat, he raised his big paw and struck at the creature. The cat was quick enough to dodge the blow, but the claws of the Hungry Tiger scraped the monkey's cage and bent two of the bars.
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.
