Ep 15. The Numbered Paper Mystery / The Sour Milk Mystery

The kids find some numbered papers blowing around the park. After investigating several possibilities of where they could be from, they finally figure out they were once fastened to trees in the park as part of a self-guided tour to celebrate Arbor Day.Huckle and his pals try to uncover why the fresh milk Farmer Pig delivered to Huckle's Dad's store was sour while the milk he delivered everywhere else wasn't. It turns out that the unusually hot weather melted the delivery truck ice that was keeping the milk from spoiling. So by the time it got to the last delivery, Huckle's Dad's store, it was sour.
