1) A group of space pirates get bored and see Earth, deciding to steal things from the planet like the sun, sky, ocean, and cheese.
2) They take the items back to their ship, not realizing these things give Earth life. A black hole then appears, starting to consume Earth.
3) Realizing their mistake, the pirates return the stolen items, but Earth is already halfway in the black hole. They use their ship to pull Earth free just in time.
