The king's daughter told him that only a crystal ball would break the enchantment. She directed him to go down the mountain, fight a wild bull beside a spring. If he killed it, a bird would spring out of it. If it was forced to let free an egg in its body, the crystal ball was its yolk, but the egg would light everything about it on fire if dropped on the land.
He fought the bull. The bird sprung free, but his brother the eagle harried it until it dropped the egg. This landed on a fisherman's hut, setting it ablaze, but his brother the whale drowned the hut with waves. The youngest brother took the crystal ball to the enchanter, who admitted himself defeated and told him that the ball would also break the spell on his brothers. The youngest hurried to the princess, and they exchanged rings.
