Kirby sets out to destroy Claycia's battleship Bastron the same way he did in the stage Kirby Rocket's Big Blastoff: by transforming into Kirby Rocket and entering the battleship. Bastron's interior is considerably more dangerous than before, now equipped with huge saw blades, Bombzways dropping mines, and Soarars towing Gordos. Kirby Rocket once again triggers a self-destruct mechanism and must flee the battleship before it detonates. The floors and ceilings attempt to crush him during his escape.
