Kirby's Dream Land 3 is the fifth platformer video game starring Kirby. Specifically, it is the third game under the Kirby's Dream Land name. Although the first two games were largely unrelated, Dream Land 3 features many returning characters from Dream Land 2. Kirby 64: The Crystal Shards was the sequel to this game.
After the events of Kirby's Dream Land 2, Kirby and Gooey are on a fishing trip, when all of a sudden, Dark Matter appears and shatters the planet's rings. He then proceeds to possess various Dream-Landers, including King Dedede. Kirby and Gooey team up with Rick, Coo, and Kine, as well as new characters Pitch, ChuChu, and Nago, in order to stop Dark Matter.
WaddleDX collects all the Heart Stars, fights the true final boss, and achieves the best ending in record time.
