Ghost Blue Ball is a ghost of Blue Ball.
He doesn't look like Blue Ball (or a ghost). He looks like a black ball with eyes twice the size, oozing vantablack liquid.
- He only appeared in Object School so far.
- He is scarier than 666.
- He is evil, unlike normal Blue Ball.
- He is believed to be one of 666's minions.
His eye now glows the color of 666, and part of his arm is cropped away, replacing the ice part. He grows devil wings.
