The Pied Piper acts as a boss encounter in the video-game "Fairytale Fights".
He is turning children into gingerbread men and is encountered in battle inside the Candy Castle, although cartoony (like the rest of the game) his fight is somewhat disturbing as it is reealed he uses his large furnace to cook many of these transformed children alive so as to feed the evil Candy Witch.

When encountered he plays an organ much like the Phantom Of The Opera and attacks using mind-controlled rats and a collection of traps fuelled by the giant furnace.
However the player-controlled hero manages to defeat him by sealing up the furnace, causing the pipe-organ to explode, killing the Pied Piper in the process.
