To open the chests you are to solve Irish riddles that are given to you by other "leprachauns." Clovers are known to make a big partof their LANDSCAPE. With the mention of rainbows and pots of gold, Ireland becomes a PERCEPTUAL REGION. However, clovers do make up a part of the Irish's ETHNIC BACKROUND.
