Leprechauns are creatures that are at the bottom of a rainbow. I have a page about rainbows so you can learn all about them. Back to leprechauns, leprechauns are Irish and normally carry a unique irish symbol the clover. When leprechauns are at the bottom of a rainbow they guard a pot of gold. Some people go crazy over leprechauns because they want to be rich and steel the pot of gold that the leprecauns guard. If you want a cool leprechaun story watch The Magical Legend of the Leprechauns.
