Korrigans

So the legends of Brittan claim that a cauldron full of gold appears at the foot of each rainbow, and that tribes of Korrigans (similar to leprechauns) are competing to be the first to find it.

Each player controls a tribe of Korrigans, scouring fields to pick up four-leaf clovers. Clovers either give Korrigan gold coins or attract companions (hares, squirrels, birds, mice, frogs, and moles) that will help their Korrigan friends move from field to field in different ways.
