One day, the birds were taking care of the eggs and a mechanical claw grabs the Birds' eggs and they follow it through a wormhole to arrive in the world of Space. There, some gain new powers or equipment. They meet Ice Bird, convinced he can help them get home, but Ice Bird is only concerned about saving his world from the Space Pigs and retrieving the Eggsteroid.
Space Pigs are the Bad Piggies, outfitted with new equipment allowing them to survive in Space and brandishing new challenges to the Flock, including the Space King's UFO (which houses the aforementioned claw) and the enormous Fat Pig.
