Osamu solves this problem by giving the chief a transistor radio and giving cigarettes to all of the islanders including the children. They are allowed to stay, but a storm rolls in and Osamu mistakes it for The Islanders' mysterious deity and proceeds to claim that they are a foolish people for fearing lightning, until he hears Kong roar and begins to pray alongside them.
