The Triplets
The Pied Piper of Hamlin
S1 E3:
In a village full of rats, the Triplets meet the Pied Piper of Hamelin. Together, they go to visit the King of the village who, it turns out, is a little boy. They make a deal with him. If they rid the town of rats the King will give them a bag of gold. The Pied Piper's music leads all the rats out of town, but the King's advisers refuse to pay the reward.
