Ball Eater

Ball Eater is the name of an achievement. To get the achievement, you gotta do what it says: eat balls . Before you eat any kind of balls, let us read the description of the achievement carefully. "Eat 200 Balls." Nasty. Go and do what it says. If you used common sense and ate the rubber balls in the Entities tab near the spawn menu, congratulations! If you ate some cooked animal balls or something else, you fail!
And don't steal other player's ball billy mays will give you and you don't need to steal.
