While Rosco is usually the troublemaker in the series, this time it's not Rosco who's been making mischief, it's the leprechauns. When Rosco's buddy, Sparks the pug, goes missing, Rosco and the kids set out to find him, embarking on real-life adventures through the St. Patrick's Day Parade. Meanwhile, Mandy thinks the leprechauns have jinxed her with bad luck because she broke with tradition and didn't attempt to lure them in with treasure in a leprechaun trap this year. Will brother and sister be able to restore Mandy's good luck, or will the leprechauns ruin her St. Patrick's Day? Find out in this heartwarming, family adventure, full of ancient Irish magic and contemporary, big-city fun. Recommended for ages 6-10.
