青蛙王子
In the tale, a spoiled princess reluctantly befriends the Frog Prince, whom she met after dropping a golden ball into a pond, and he retrieves it for her in exchange for her friendship. The Frog Prince, who is under a wicked fairy's spell, magically transforms back into a handsome prince. In the original Grimm version of the story, the frog's spell was broken when the princess threw it against the wall, while in modern versions the transformation is triggered by the princess kissing the frog.
