lets talk about leprechauns and the irish folklore behind them
I find the idea of Leprechauns quite interesting.
yes most of the time they are little men wearing a coat
Is it true that they find or are looking for gold?
no but it's interesting they claim in folklore that if you catch one it grants three wishes and not gold 
Oh really?  That sounds a lot better than gold.
creatures rarely appear in Irish mythology and only became prominent in later folklore.
Etymology.
The name "leprechaun" is derived from the Irish word , defined by Patrick Dinneen as "a pigmy, a sprite, or leprechaun". The further derivation is less certain; according to most sources, the word is thought to be a corruption of Middle Irish "luchrupán", from the Old Irish , a compound of the roots "lú" ("small") and "corp" ("body")
Leprechaun
A leprechaun () is a type of fairy of the Aos Sí in Irish folklore. They are usually depicted as little bearded men, wearing a coat and hat, who partake 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, they often grant three wishes in exchange for their freedom. Like other Irish fairies, leprechauns may be derived from the Tuatha Dé Danann. Leprechaun-like
