A leprechaun is a type of mythical creature from Irish folklore. It is typically depicted as a small, mischievous, and often grumpy old man who wears a green coat, hat, and shoes. According to legend, leprechauns are shoemakers by trade and are known for their love of gold and their ability to grant wishes. They are said to be quite tricky and will often play pranks on humans. If captured by a human, a leprechaun is said to grant them three wishes in exchange for its freedom. Leprechauns are often associated with St. Patrick's Day celebrations and are a popular symbol of Irish culture.
