“The Little Brother and Sister” is a tale from the Brothers Grimm about two siblings escaping their abusive, witch stepmother. She enchants all water sources in the forest to transform anyone who drinks from them into an animal. The sister successfully warns her brother twice, preventing him from becoming a tiger and a wolf, but he drinks from the third stream, turning into a deer. The sister ties her gold chain around his neck and they live in the woods until the king discovers them during a hunt. He marries the sister, who later gives birth to a son, but the wicked stepmother returns, kills the queen, and replaces her with her own daughter. The ghost queen visits her child and the deer every night, which the king discovers, leading to the restoration of his wife, the transformation of the brother back into a human, and the punishment of the stepmother and her daughter, who are killed. They all live happily ever after.
