Synopsis
A princess had a magical tower with twelve windows, and whenever she looked from a window, she saw more clearly from it than the one before. Being haughty, she had no wish to marry, and decreed that any suitor must hide from her to win her, but if she found him, he was to lose his head. After ninety-seven lost their lives, three brothers presented themselves, and the first two lost. The youngest son asked for three tries. He went hunting and spared a raven, a fish, and a fox. The raven tried to hide him in an egg, where he could be seen only from the eleventh window. The fish swallowed him, where he could be seen only from the twelfth. The fox turned him into a pretty "sea-hare" (an uncertain mammal) and sold him to the princess. When she went to the windows, he hid in her hair. She could not see him, and angrily threw the sea-hare out of her hair. He sneaked off, the fox restored him, he went to claim her, and they married.

Adaptations
Two Hungarian variants of the tale were adapted into episodes of the Hungarian television series Magyar népmesék ("Hungarian Folk Tales") (hu), with the titles Zöld Péter ("Green Peter") and Kiskondás ("The Little Swineherd").
