to the coordinates, as they are the only ones willing to take them. The helicopter gets caught in a cyclone and they crash into the Pacific, waking up on the island. Moving inland, they are shocked to discover miniature elephants (which belong to a prehistoric species, the Dwarf sicilian elephant) and giant butterflies. After coming across an egg clutch, Gabato accidentally wakes up a giant frilled lizard, which chases them throughout the jungle. They nearly get eaten, but are saved by Alexander. He takes them to a hut he built from the wreckage of the ship that brought him to the island. He has a working radio, but due to the positioning of the satellite, it will be two weeks before they can call out. The next morning, Alexander leads the group to the lost city of Atlantis, which rises every 70 years and sinks again after a couple of days. Their only means of salvation seems to be the legendary Nautilus, Captain Nemo's submarine. Kailani enters Nemo's crypt and finds his journal, which shows that Nautilus is in a cave at Poseidon's Cliffs. To go there, they mount giant bees and fly over a high ridge. When giant bee-eater birds try to devour them, Sean saves Kailani's life, but dislocates his ankle. Hank and Alexander reset Sean's ankle, then the group has a bonding moment when Hank sings his rendition of "What a Wonderful World" to ease Sean's pain. The next morning, the water rises greatly and Hank deduces that the island will sink in a matter of hours. Gabato is missing, having gone toward the island's volcano in search of gold. While Alexander and Kailani go after him, Sean and Hank head for Poseidon's Cliffs. To reach Nautilus underwater cave, Sean and Hank create makeshift oxygen tanks and dive down fifty feet, but are nearly killed by a giant electric moray eel. The 140-year-old batteries have run down, so they engineer a way to start the submarine with the eel's electricity. Kailani and Alexander find Gabato and convince him to escape with them instead of trying for the volcano. As they near Poseidon's Cliffs, the volcano erupts. Sean and Hank arrive in Nautilus just in time to rescue the others from the water. Gabato pilots the submarine out of harm's way while Hank and Sean fire torpedoes into the path of falling debris. As they clear the dangers,
