A disco ball that will shatters into several fragments after a while.
Just like all flares, it will bounce several times before landing. Due to the high area covered, you may still damage the enemy if it lands a little offside.
Best used when there are several enemies in an area, to hit as many as possible, or to land below a 2x Buff powerup. Due to the spread, it's likely to grab the buff shot with a projectile.
Groovy Ball: The disco ball will snap out of it's rope and fall below, exploding in the same fashion as the Shrapnel. Because of this, the Groovy Ball is best used instead against single targets. If the ball lands on the enemy, it will take massive amounts of damage.
