In the evening, while looking at the sky, Findus asks Pettson if there are people living on the moon and if they might fall down to earth if there were an earthquake on the moon. And sure enough, in the middle of the night a man falls from the moon into a nearby field. Findus wants to help the stranger get back home to the moon. They come up with some very original ideas about how to make this happen, which unfortunately do not work. Finally, an astonished Pettson comes to the rescue.
