Back on the ark, the youngest sister, Nemo, tells his two older sisters, Hamu and Jeanne, that they've been missing for a while. They've come to find the last remaining elephant turtle, and they need them to help them find it. First, they need to figure out where the turtle is hiding, because the military base where they're staying is right next door to the turtle's hiding place. The captain tells them that they have a problem: the island's leader, Nestor, has been dead for a hundred and a half years, and he cursed Nemo when he first came to the island. He's also responsible for the deaths of all the other animals on the island, including the turtle. Nemo asks the girls if they can help him find the turtle, but they can't. They don't know what to do, since the island is being used for "nuclear testing" on humans.
