Leprechauns were known for hiding pots of gold in hollow tree trunks, caves, abandoned mines, or at the end of rainbows. They are often depicted wearing three-cornered or cocked hats and dressed in a shoemaker’s outfit usually in the color green. Mischievous leprechauns sometimes raid wine cellars when engaging in revelry after a hard day's work, such leprechauns are called "cluricauns" (kloor-a-kawns), often seen riding the backs of sheep or shepherd's dogs in a drunken spree. These elves are also well known for making shoes and brogues and often wear leather aprons while working. The sound they make when hammering shoes often gave away their presence.
If caught unaware, a leprechaun can be threatened with bodily harm in order to give away the location of their pot of gold. However, leprechauns often trick their captors into glancing away at the last moment, at which point they immediately escape. Leprechauns are widespread in Ireland and the nearby isles. The word leprechaun itself was coined by Thomas Keightley, in The Fairy Mythology (1850) derived from the word "luberkin," an Elizabethan name for a brownie-like fairy. It is also possible that the word leprechaun was also derived from the Old Irish word “luchorpan," or "little body". I don't know who wrote this song. I got it at The Caverns of Blood
