When they finish their daily tasks, leprechauns like to organize wild feast, during which time they are referred to as cluricauns. These (often drunk) cluricauns can then be seen riding in moonlight on the back of a dog or a sheep.
According to popular belief, a leprechaun possesses a treasure (usually a pot of gold) which a human may obtain if he succeeds in capturing one, which is extremely difficult. Even after capture, a person may not take his eyes off of him for an instant, for then he will vanish. Leprechauns are mainly found in Irish folklore.
