Rats were running wild through the quiet little town. They posed a health hazard and were terrorizing the people. The town mayor announced a prize of 500 gold coins to anyone who could get rid of the rats. Many people approached the mayor with their solutions. None of them succeeded.

One day, a piper came into the town playing a sweet tune on his pipe. He went to the mayor’s office and claimed that he would rid the town of the rats. The mayor promised to give him the 500 gold coins if he was successful. The piper played a tune, and all the rats started following him. He led them up a cliff and let them drop into the river below. The rat menace ended.

The next day, the piper approached the mayor and asked for his prize. The mayor refused. The angry piper rushed out of the mayor’s office. As he ran, he piped a tune.

All the town’s children came out of the houses and followed the piper up the mountain. Neither their parents nor anyone else could stop them. The children filed into a cave in the mountain, and the rock that covered the cave door moved back to close it.

The townspeople worried about the children. However, they were only in the cave a short while because the mayor decided to pay the piper.

The mayor learned a valuable lesson while trying to rid the town of rats.
