Captain John is always busy sailing his ship transporting goods from far and wide. This is no easy task, because sometimes the parcels are long and thin, sometimes they have lots of corners or they are simply round. Now and then a great wave splashes onto the ship and sweeps a chest overboard. However, it is sometimes possible for the captain to fish the chest back on board again. If he maneuvers his ship well, the captain will manage to get all the goods to their destination safe and sound.
