Fairy from Irish folklore.
A leprechaun is a type of fairy in Irish folklore. It is usually depicted as a little bearded man, wearing a coat and hat, who partakes in mischief. They are solitary creatures who spend their time making and mending shoes and have a hidden pot of gold at the end of the rainbow. If captured by a human, the leprechaun has the magical power to grant three wishes in exchange for their freedom. Like other Irish fairies, leprechauns may be derived from the Tuatha Dé Danann. Leprechaun-like creatures rarely appear in Irish mythology and only became prominent in later folklore.
