Everything about this item is exactly the same as its previous counterparts (the Red Ball, Blue Ball, and Green Ball), except for its color. The feature that makes these balls valuable is the number on the ball. It is an identification number, showing how many balls were unboxed by players in the game before that one. For example, if a ball has the number 383, then that ball is the 383rd ball that has ever been unboxed in the game.
It also has the ability to roll when in motion and be moved by Conveyors, except for Tilted Conveyors, in which the balls are unable to be elevated.
