The Leprechaun is a character of Irish folklore; clever and insidious creature. They get pleasure from cheating. Each of them has the pot of gold. They like to drink. Their profession is shoemaker. The legend says that, if you catch the Leprechaun, he will have to do 3 wishes or show where he keeps his gold.
