When Kirby and his friend Gooey are fishing on a pleasant, sunny day, a strange black cloud begins to appear over Dream Land. It spews many other smaller black clouds out of itself across the lands. This black cloud was Dark Matter, a well-known Kirby villain today. Kirby and his friends then set off to save Dream Land from Dark Matter.
