david ogden stiers is the uncredited narrator heard at the opening of the film, explaining how: the magical narf of the undersea blue world provided guidance to humanity millennia ago; humanity has forgotten that relationship, plunging itself into the devastating wars that are referenced through the remainder of the film; seeing the looming end of humanity, the narf have now sent some of their (human-appearing) young to help humanity, though most are killed by the scrunts and humanity has forgotten how to listen to the others.
