The Pied Piper of Hamlin

The town of Hamelin has a rat problem. Thousands of rats and nobody knows what to do about it. A young man offers to rid the town of rats for a price, and the town council gladly agrees. The Pied Piper blows his horn, and the rats all follow him right into the sea, where they drown. When the Pied Piper returns to collect his fee, the town council refuses to pay. The Pied Piper blows his horn again, and all the children of Hamelin follow him right through a mountain.
