The pied piper of hamelin.
A long time ago, there was a small city named Hamelin in Germany. Unfortunately, the city was infested with rats. The rats ate up people's food and bit babies in their cradles.
The people released cats to kill the rats. But the rats even threatened the cats. Then one day, a mysterious man with a pipe in his hand showed up and came to the mayor. I'll get rid of the rats. When I do give me a lot of money.
Of course I will. Just as long as you get rid of the rats. The mayor promised.
Standing in the city square, the man began to play the pipe. Magically, rats from all over the city began to follow him.
Playing the pipe, he went to the river and entered the water. All the rats also went into the water after him. Eventually, the rats all drowned. People watching this were amazed and cheered.
Give me the reward as you promised, the Piper said. But the mayor changed his mind.
Hmm, all you did was just play some tunes. I can't give you the money. The Piper was very angry. You'll regret not keeping your promise.
After a while, the Piper came back and began to play the pipe again. This time, children gathered one by one and all followed the mysterious sound. While playing the pipe, he entered a large cave in the deep forest with all the children following. And after that day, no one heard from the children again
