Leprechaun

A leprechaun (Irish: lucharachán/leipreachán/luchorpán) is a diminutive supernatural being in Irish folklore, classed by some as a type of solitary fairy. They are usually depicted as little bearded men, wearing a coat and hat, who partake in mischief. In later times, they have been depicted as shoe-makers who have a hidden pot of gold at the end of the rainbow. Leprechaun-like creatures rarely appear in Irish mythology and only became prominent in later folklore.
