The Pied Piper of Hamelin
The Town Council of Hamelin is worried because the town is infested with rats. The Pied Piper plays a magical, sad tune on his pipes and leads all the rats into the river. But the Mayor refuses to pay him the agreed fee, so now the Piper plays a very cheerful tune on his pipes luring away all the boys and girls of Hamelin. The Mayor begs his forgiveness, pays him what his due, and the children return to Hamelin.
