Leprechaun

The Leprechaun, sometimes known as the Clauricorn, is a mischievous magical creature, although it is not malicious. They have a reputation as pranksters, but have never inflicted lasting damage on a Human. Native only to Ireland, they are fully sentient and capable of speech but have never requested the Ministry of Magic to reclassify them as Beings. Green in colour, the Leprechaun reaches a height of around six inches, and normally wear clothing made out of leaves. Leprechauns main diet consists of vegetation, primarily leaves.

Although they are humanoid-like creatures, it is unlikely that they are related to humans or any other human-related beings, such as goblins.

Leprechauns live in forests and wooded areas, and they enjoy attracting Muggle attention to themselves. This tendency has led to them being heavily integrated into Muggle children's stories and legends. Leprechauns have the ability to create a gold-like substance that disappears, much to their amusement, after a few hours. Much of this Leprechaun gold is created in the form of Galleon coins. Ludo Bagman paid Fred and George Weasley in Leprechaun gold-galleons when he lost a bet concerning the Ireland and Bulgaria Quidditch teams during the Quidditch World Cup. Ron paid Harry in it as well to cover the cost of the Omnioculars that Harry got for him to view the match. Ron was very upset when he found out the gold disappeared, and that he hadn't really paid back Harry at all, but Harry didn't mind.

Behind the scenes
