Once upon a time lived in Krakow the duke Krak. The duke was a very good ruler but he had one big problem – in a cave below his castle huge dragon lived. The dragon ate cows, ships, horses and other animals, what is more, sometimes eat also the people. The duke decided to kill the monster. Invited the strongest man, brave knights to his castle and promised to give a half of his kingdom and daughter to the one who kill the dragon. Unfortunately nobody could defeat the beast, some knights died, some escape seeing the dragon.
One day one shoemaker Skuba visited the duke Krak and promised to kill the beast. Krak did not believed, this boy could defeate the dragon but agreed. Skuba killed a sheep, put sulfur inside, saw the skin and gave it to the dragon. The dragon ate the sheep and suddenly felt fire in its stomach, went to the river, and drunk, drunk, drunk, was becoming bigger and bigger, and suddenly explode. Krakow was saved and the shoemaker Skuba became successor of the duke Krak.
