Leprechaun:

[Chronos]

A leprechaun is a small sprite that lives in farmhouses or wine cellars. Like Brownies they aid humans and accomplish small labors for them, they ask humans for supplies and furniture in return they give objects that bring luck and fortune. Leprechauns are described as merry little fellows that dress in old-fashioned green clothes with buckled shoes and they wear a red cap. They are known as fairy cobblers, as they make shoes for other elves. They never make a pair of shoes they only make one. Popular belief is that a leprechaun possesses a treasure, which a human can obtain if they succeed in capturing one, which is very difficult. Leprechauns are mainly found in Irish folklore but do appear in other countries.
