A pot of gold at the end of the rainbow - a pot full of St. Patrick's Day wishes.
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.
In traditional festive legend, Santa Claus's reindeer pull a sleigh through the night sky to help Santa Claus deliver gifts to children on Christmas Eve.
