Eternal Planet Halfmoon is one of the planets which Kirby can visit in Milky Way Wishes, in Kirby Super Star and Kirby Super Star Ultra. It is a planet beyond the realm of sense, with all sorts of different starry and windy environments. Computer Virus serves as the boss of this planet, though it has tougher enemies to battle than the one in The Great Cave Offensive. Halfmoon is home to two Copy Essences Deluxe. These are Mirror and Ninja.


The stage begins as Kirby flies up through a field with a view of outer space. He lands and bounces across three stars before reaching the door to the next area.

Kirby then finds himself in a grassy zone with a very strong breeze throughout and a rapidly scrolling starry background. Kirby will need to contend with enemies, spikes, and pitfalls as he fights the wind, but a Warp Star can be accessed in the middle of the path to let Kirby skip the rest of it if he wants.

In the following area, Kirby must traverse a starry cavern while walking and riding Carts across stardust floors. The path continues to the right past several stops and starts until a door is reached at the end.

In the following area, Kirby can ride another Warp Star to quickly move through a tunnel of hazards, but if he takes it, he will fly right past a couple valuable items. At the end of the flight path, Kirby is ambushed by Iron Mam and Chef Kawasaki simultaneously. The door appears once both are defeated.

The next area features a strong updraft. Kirby must make his way up past several cliffsides with foes and hazards occupying them. Along the way, Kirby must pass through a suspended pool of water to find the door up at the top. This door leads to the Computer Virus boss.

Copy Essence Deluxe guide[edit]

The following is a basic guide on how to reach each Copy Essence Deluxe on Planet Halfmoon:

From the Mine Cart tunnel in the stars, Kirby can find a star block in the floor which leads to a room containing this essence.
From the upward-draft flight through the tunnels, this essence can be found through a doorway blocked off by a bomb block barrier.

Boss: Computer Virus[edit]

"Kirby attacks!"
Main article: Computer Virus

Computer Virus serves as the boss of this stage, though this time, the fight is different. Instead of starting with the Slime, the boss starts with the Magician, and then follows with the Evil Knight and the Great Dragon. Just like before, the fight takes place in turns, and Kirby is given a bunch of superfluous point gains after the fight is over. Defeating Computer Virus clears the stage.


  • In Kirby Super Star only, one of the decorative pieces of scenery in the starry cavern area with Carts is Mimas, one of Saturn's moons.
