Space Oohroos appear in Stage 10 of Volcano Valley, where two of them take a secret switch on a small ship and fly away from the Kirbys, and also on Stage 11. They attack the same as regular Oohroo, but are also known for activities such as locking the Kirbys in a room, sounding alarms, and trying to prevent the Kirbys from finding out what they're up to. They also have a trusty spaceship that they use to fly away from intruders.
