August Leskien collected another variant, Von dem Königssohn, der auszog, um seine drei Schwestern zu suchen, wherein the animals are a falcon, a griffin and an eagle. After their marriages to the hero's sisters, the avian brothers-in-law gather to find a bride for him. They tell of a maiden the hero must defeat in combat before he marries her. He does, and, after the hero and the warrior maiden marry, she gives him a set of keys. The hero uses the keys to open a chamber in her castle and releases an enemy king.Leskien, August/Brugman, K.
