Pig lives at the top of a hill in a town surrounded by a destructive, dark cloud. Before Pig’s father leaves to find a solution to the cloud, he builds Pig a small wooden dam to protect him and the town. Young and alone, Pig finds love and family through his friendship with Fox, and continues to care for the townsfolk in a variety of ways. However, Pig struggles with the absence of his father, and his desire to search for him competes with his need to keep the town safe.
