"The ball explodes!?" —Rookie
"Only when we score." —Flynt

The Bomb aka the Grifball is the ball used in Grifball matches. Anyone who picks up the bomb immediately turns orange and becomes the Grif. In Halo 3 and Halo: Reach, the ball explodes immediately after the Grif scores. As Halo 4 doesn't feature Assault, the bomb has been replaced with the Oddball skull. The new ball can be affected by physics (such as Gravity Hammer blows) and doesn't explode at the end of the round. After a later playlist update, the goals now emit energy bursts reminiscent of the traditional explosions when a goal is scored.
