Fearing for his subjects, the king sends his warriors to slay the dragon. After this fails, the son of a poor shoemaker decides to outwit the dragon. He stuffs a ram skin with tar and sulfur before tricking the dragon into eating it. The dragon panics and tries to quench it's sudden thirst from a nearby river. Because of its greed, it drinks so much that it bursts.
