The Frog Prince

The Frog Prince, is a fairy tale, best known through the Brothers Grimm's written version; traditionally it is the first story in their collection. In the tale, a spoiled princess reluctantly befriends a frog (possibly meeting him after dropping a gold ball into his pond), who magically transforms into a handsome prince. Although in modern versions the transformation is invariably triggered by the princess kissing the frog, in the original Grimm version of the story, the frog's spell was broken when the princess threw it against a wall in disgust. In other early versions it was sufficient for the frog to spend the night on the princess's pillow.
