To help Olimar are indigenous creatures called Pikmin, which are nearly extinct and unable to survive in the environment without direct leadership. As this element of symbiosis develops, Olimar discovers parts of the "Dolphin" and travels across the Pikmin Planet, which is assumed to be Earth, albeit with fictional fauna and far after the extinction of humans. The game has three endings depending upon how many ship parts the player successfully reacquires. Two good endings occur should the player retrieve all thirty parts or twenty-five necessary parts, and a bad ending occurs should the player fail to find twenty-five parts.
