Once outside, the castaways reunite and meet Captain Nemo, who is living aboard his disabled submarine. Nemo has been watching the castaways and secretly assisting them by sending the chest, shooting the giant bird, and sinking the pirate ship. He invites them to dinner aboard the "Nautilus", where he tells them that the giant creatures are results of his genetic experiments to enlarge the world's food resources, thereby eliminating hunger and economic competition which he sees as prime causes for the wars he was striving to end all his life. Due to their fortitude, he has selected them to assist him in his efforts to make his achievements known to the world, especially since the "Nautilus" is incapacitated beyond repair and the volcano will soon erupt, destroying the island.
