Explanation: In the story, the fisherman's wife obligates him to go with the mystical flounder that has magical powers, she forces him to wish for more and more luxuries each time, but every time the man goes back to the flounder, the scenery is darker, creepier, and has worse climate conditions than before. Even though the man does not want to go and make a wish, the conditions of the weather make it clear that they are going too far, and should stop making greedy wishes.
