Not a tall creature, the leprechaun can be easily confused with 10 years old human child when looked at from a distance. A better look reveals brown, wrinkled skin and visage resembling a young gnome.
Leprechauns are merry, clever and quick while at the same time sly and malicious rogues. They are also crafty and often seen working on a shoe, which is all the more interesting as it's always over one, but never pair.
Even though the leprechaun is witty, it pays to try to outsmart him as each of them is in possession of an ingeniously hidden pot full of gold. In the old days, leprechauns used to bury such a pot where the arc of the rainbow ended. But because humans - even those stupid - knew about this custom, leprechauns changed it and now they hide the treasure more cleverly.
