===Final boss===
The Sea Door is located in two rooms to the right of the top-left corner. It will only open once all three key fragments have been found. Once this is done, the player can open it by interacting with it the same way one would with a penguin. Speaking of penguins, the crewmate from before is beyond the door, and he gives out the code to the final boss battle, like a save point.

Upon entering this code, another door will open, revealing a bridge leading into the ocean. Here, the player will meet the final boss, a blue, circular, floating robot with what appears to be a penguin inside.

In Phase 1, the player must navigate several rooms, each containing obstacles such as spiked blocks. The boss will fire lasers periodically while also moving around. The fifth room ends up being a dead-end, where Phase 2 begins.

In Phase 2, the boss obtains two additional laser cannons. The player must survive its shots while waiting for a white beam of light to appear from one of the boss' laser cannons (or the boss itself). Touching this beam of light damages the boss, and the player has to reduce its health to 0. At 66% health, the boss also gains an additional laser cannon that fires horizontally and follows the player. At 33% health, the boss can fire three projectiles at the player.

In Phase 3, the boss retreats, and the player gets a wooden plank to ride on and chase it down. The boss soon regenerates, and the player now must survive the boss' attacks for a short time as lightning whittles down the last bit of its health. Once it hits zero, the boss explodes.

One final cutscene plays, and it is revealed that the penguin controlling the boss was the boss itself, who had taken the player's human (or, in this case, penguin) appearance. The penguins are grateful for the player's success.
