Leprechaun

The leprechaun is a fairy in  Irish Folktales.

He wears green clothes and buckled shoes. Leprechauns  were  cobblers   and  whoever  wore the shoes he made would have good luck.

In many tales leprechauns kept gold at the end of the rainbow, and if caught by a person they had to give up their gold.

Leprechauns played tricks on people and got away.
