Duck and Diving is a rhyming magazine story.
Duck is confused about marine life, but his driver tells him that the sea is another world, full of all kinds of different animals. Then, the driver tells Duck about the aquarium and all the types of marine life that live there including dogfish and catfish, which confuses Duck more. Duck's driver has an idea and decides to bring some pictures of the underwater wonders of the sea to show the engines on a projector at the sheds. That night, the engines marvel at the impressive photographs and Duck wishes he could be a diver.
