[3] Guests board a small submarine developed by Captain Nemo and participate in a tour to explore the world under the sea.

The place where the guests end up was a world of Atlantis where mermen live.

The submarine was boosted by the mysterious power of the mermen, and was able to return to the base safely.

This attraction's concept is similar to Disneyland's Submarine Voyage and Magic Kingdom's attraction 20,000 Leagues Under the Sea: Submarine Voyage.

This ride does not go through real water; the movement and bubbles in the window are added effects.
