This stage is notable for the introduction of the Kirby Rocket transformation. Elline transforms Kirby into the powerful machine and he promptly soars through Bastron’s tailpipe. Now inside the battleship, the hero must fly through the corridors and pass over panels in order to progress through Bastron's interior. Kirby Rocket eventually hits a giant switch, prompting a self-destruct sequence. In order to escape, the hero must hit three wall panels and unlock an exit door before time runs out.
