Frog Families! is a De Agostini magazine story.
Duck decides to stop at the pond to watch a big white swan. When he arrives at the pond, the swan is nowhere to be seen, but Duck hears some strange croaking noises. His driver thinks there may be some frogs in the pond and, to Duck's surprise, two frogs leap out of the water. Then, Duck spots even more frogs and his driver spies some frogspawn. The driver goes onto explain how tadpoles hatch from the frogspawn and, in turn, the tadpoles develop into frogs. Duck decides that he will look out for baby frogs every time he puffs past the pond. Duck then whistles goodbye to the frogs and steams on his way.
