A chair stood near the window, and this--showing dimly in the moonlight--gave him an idea. By pushing against it with all his might, he found he could move the giant chair a few inches at a time. So he pushed and pushed until the chair was beneath the bird-cage, and then he sprang noiselessly upon the seat--for his monkey form enabled him to jump higher than he could do as a boy--and from there to the back of the chair, and so managed to reach the cage and take it off the peg. Then down he sprang to the floor and made his way to the door. "Open!" he commanded, and at once the door obeyed and swung open, But his voice wakened Mrs. Yoop, who gave a wild cry and sprang out of bed with one bound. The Green Monkey dashed through the doorway, carrying the cage with him, and before the Giantess could reach the door it slammed shut and imprisoned her in her own bed-chamber! The noise she made, pounding upon the door, and her yells of anger and dreadful threats of vengeance, filled all our friends with terror, and Woot the Monkey was so excited that in the dark he could not find the outer door of the hall. But the Tin Owl could see very nicely in the dark, so he guided his friends to the right place and when all were grouped before the door Woot commanded it to open. The Magic Apron proved as powerful as when it had been worn by the Giantess, so a moment later they had rushed through the passage and were standing in the fresh night air outside the castle, free to go wherever they willed. Chapter Eight The Menace of the Forest "Quick!" cried Polychrome the Canary; "we must hurry, or Mrs. Yoop may find some way to recapture us, even now. Let us get out of her Valley as soon as possible." So they set off toward the east, moving as swiftly as they could, and for a long time they could hear the yells and struggles of the imprisoned Giantess. The Green Monkey could run over the ground very swiftly, and he carried with him the bird-cage containing Polychrome the Rain-bow's Daughter. Also the Tin Owl could skip and fly along at a good rate of speed, his feathers rattling against one another with a tinkling sound as he moved. But the little Brown Bear, being stuffed with straw, was a clumsy traveler and the others had to wait for him to follow. However, they were not very long in reaching the ridge that led out of Mrs. Yoop's Valley, and when they had passed this ridge and descended into the next valley they stopped to rest, for the Green Monkey was tired. "I believe we are safe, now," said Polychrome, when her cage was set down and the others had all gathered around it, "for Mrs. Yoop dares not go outside of her own Valley, for fear of being captured by her enemies. So we may take our time to consider what to do next." "I'm afraid poor Mrs. Yoop will starve to death, if no one lets her out of her bedroom," said Woot, who had a heart as kind as that of the Tin Woodman. "We've taken her Magic Apron away, and now the doors will never open."
