A beast which came from data about a Russian space probe thing that was sent into space many decades ago. I doubt that the actual Sputnik probe had a large blue moon on its forehead, though. But it would have been more exciting if it did!In-game description

Sputniks cannot be found in the wild. They are not used by any enemy signers, except for those participating in the Random Tournament.
