The three leprechauns Ari, Boo, and Col have a job to do. They must race to where they've buried the pot of gold and dig it up before the rainbow comes. The clouds are already gathering, so there'll be no time for mischief along the way. But Mrs. Ballybunion's cow, Miss Maud Murphy's hen, and Old Jamie soon find out that the three clever fellows can't resist having a little fun on the road to Paddywhackers Bog. For, in addition to putting a pot of gold at the end of a rainbow, mischief is what leprechauns do! Delightful illustrations from a Caldecott medalist and a playful text written in a lilting Irish style make this a perfect story for St. Patrick's Day or any other time of year. Includes an author's note about leprechauns and rainbows.
