Steadibrick made this 19 inch tall version of the CMF Leprechaun. It is currently on display at the Fairview LEGO Store in Toronto.

Leprechauns go back to at least the 8th century in Irish folklore, first appearing in the Echtra Fergusa maic Léite, though the guy with the green top hat is really only about a hundred years old, so it's a bit of an anachronism to post him in the Castle MOC forum, but this is just too nice a MOC to overlook.
