“There was once a king. He consulted a fortune teller to find out the future of his only daughter, whom he loved very much. When he found out that his daughter was going to be stung to death by a snake, he built a castle on the sea for the princess. Thinking that he had thus secured his life, the king one day sent a basket of grapes to his daughter. However, the snake hiding in the basket stung the girl to death.”
