|“||A spaceship has been sighted in this area. It sounds like a formidable vessel.”|
|— Daroach • Kirby Mass Attack|
The Space Oohroo spaceship appears in Stage 10 of Volcano Valley, where the Space Oohroo take a secret switch inside. They then fly away and the Kirbys have to build a spaceship of their own. When they do, they have to fly after the ship and get the switch back.
When the Kirbys catch up to the Space Oohroo spaceship, they have to use the ship's guns and fire at the guns the Space Oohroo are activating. If the guns aren't shot at in time, the Kirbys' spaceship will take damage.
In this phase, the long guns are still the main target and must be fired at. From time to time, short guns will activate, but immediately retract, to trick the Kirbys into thinking that they are the real guns.
In the final phase of the battle, some umbrella-like guns appear and if they are fired at, they will absorb the projectile and fire back at the Kirbys' ship, so the player has to watch carefully. Stage 10 ends after the Space Oohroo spaceship is destroyed.
