When Piggley, Ferny and Dannan hear strange noises in the barn, Piggley decides it’s the “song of the banshee”—which frightens Dannan more than she wants to admit! When she finally confesses her fear to her friends, they search for the source of the noise…and discover it's only Wiley the sheep trying to lead his uncooperative flock in song.
