Ep. 18: Captain Nemo sails the Nautilus to Antarctica to repair damage from Gargoyle while escaping a giant squid.

18

To repair damage from Gargoyle, Captain Nemo orders the Nautilus to sail to Antarctica. Passengers are horrified, with Sanson complaining about the unstable ice and Jean excited for the journey. Upon arrival, an ancient squid attacks the submarine. The crew tries ramming an iceberg to dislodge the creature, but this fails. They eventually succeed by steering toward an underwater volcano. The intense heat forces the squid to release its grip and drift away. The Nautilus then proceeds through a tunnel to reach its subterranean base. This sequence resolves the immediate threat while continuing the vessel's journey to the southern pole region.
