While on their seemingly endless trek back home to Greenpatch, Blinky Bill and his friends stumble across a lighthouse. Once inside, they find a sea bird and a penguin lighthouse keeper in the middle of a heated argument. The sea bird wants the penguin to extinguish the lighthouse as they believe that the penguin is using the light to catch all of the fish that the sea bird needs for her chick. However, what happens when the chick gets lost at sea in the middle of the night? Will the penguin be willing to help the sea bird? Will the lighthouse be used? Will the chick be found? And how will their argument finally be resolved?
