T.C. Croker via WikimediaBelieve it or not, this is the best public-domain picture available for a clurichaun.
Fond of tippling, the cluricaune would steal into wine cellars, especially those belonging to alcoholics, to steal a few bottles. He was hard to exterminate, for if an owner tried to move, the cluricaune would simply travel along inside a cask.
One cluricaune named Little Wildbeam, who haunted a Quaker family in Cork, was most helpful if a servant left a bit of beer dripping from the cask; he shrank and wedged himself into the spigot so that not a drop was lost. If the maids did not feed him well, the fairy came out at night and beat them senseless.
I swear this is an actual piece of Irish folklore and not a 19th century racist caricature of an Irishman.
