Leprechauns are small, mythical creatures from Irish folklore, often depicted as little men dressed in green coats and hats. They are known for their mischievous nature and are often associated with rainbows and pots of gold. According to legend, if you catch a leprechaun, he must grant you three wishes or reveal the location of his hidden treasure. These creatures are considered a type of fairy and are often portrayed as cobblers, making and repairing shoes. Leprechauns are part of the rich tapestry of Irish mythology and are celebrated during St. Patrick's Day festivities, symbolizing luck and the spirit of Ireland.
