After defeating King Dedede, Kirby will place the Star Rod in its pedestal at the Fountain of Dreams but something ominous will occur. You’ll next battle a dark matter ball and the only weapon you can wield is the Star Rod. Shoot some stars to attack and watch for starry debris shot from the boss. The stars and sound waves will be shot at different spots so focus carefully as you move. After defeating the dark matter ball, use the Warp Star to go to the moon. The final boss is known to be Nightmare. This boss will attack by throwing stars and moving around. Once its cape opens up, aim for the massive swirling abdomen of the boss. After several hits with the Star Rod, Nightmare will be defeated and you have completed the game.
