The engines tease Duck about his whistle, especially Mike who says engines without whistles are improper engines. Later, he pulls passengers on the line and encounters a cow. He blows his whistle so hard that it flies far away into a field. Mike insists they look for his lost whistle, but the passengers decide to whistle for him instead.
