This is a two-player game. Player one uses W, A, S, and D to move the red submarine. Player two uses the arrow keys to move the blue submarine. Avoid going off the track and avoid bumping into any Mad Jelly Dudes. Whoever collects the most coconuts wins. Hint: Look off the road, you might see a familiar alien octopus.
After getting all his coconuts back and saving Gerald the Ghost, Nano "purposely" crashed into the ocean, where the coconuts fell out of the space shuttle again and the space shuttle became a submarine. But the Coconut Protector King and Space Dog followed Nano. Space Dog followed him because he still thought Nano was a space pirate and also thought he would return to space to kidnap the Space Bots. The Coconut Protector King and Space Dog then hopped into an abandoned submarine. But both teams didn't get the coconuts on time. A weird shark who thought everyone and everything he knew was in a video game claimed the coconuts and said: "I will give all the coconuts to whoever collects the most coconuts when I throw them on this race track." He then gestured to a nearby race track and both teams agreed to the challenge. This is the third installment in the Nano's Journey series.
