to use until the second great need of her life; the third night, they are hosted at the youngest brother's castle, and the daughter is given a final gift of a beautiful plum, not to be used until the third great need of her life. At last, the girl and the bull arrive at a valley of glass. "You must wait here," the bull tells the girl, "and whatever you do, do not move, even an inch, or I will not be able to find you". He goes on to explain that he is to fight the devil who rules the valley so that they may exit. If the sky turns blue, then she will know that the bull has won; but if the sky turns red, then he has lost. The black bull leaves the girl there, and after some time she sees the sky turn blue. Overjoyed, the girl shifts her position slightly... and so the black bull does not return for her. Unable to climb out of the valley on her own, the girl wanders alone until she finds a blacksmith. He tells her that if she serves him for seven years, he will repay her by making her a pair of shoes. When seven years have gone by, the blacksmith, true to his word, makes the girl—now a young woman—a pair of iron shoes, and nails them to her feet. With the shoes, the young woman is able to climb out of the glass valley. The young woman eventually wanders back to the home of the witch, who offers her shelter if she will wash some bloody shirts that both she and her daughter have been unable to clean. Whoever could clean the shirts would marry the gallant young knight staying at the witch's home, whom the shirts belong to. Despite the failure of those before her, no sooner has the young woman touched the soap to the shirts than the bloodstains vanish, and the young woman's feet heal perfectly, as if they had never been bloodied or injured. Delighted, the witch brings the knight his shirts and convinces him that it was her daughter who cleaned them. Thus, the knight and the daughter are to be married. Desperate, the young woman realizes that she is in the first great need of her life. She breaks open the apple, and finds it full of rich jewelry.
