Icebox is the fourth Guardian in Blasterball 3. It's encountered on Stage 40. Icebox is a giant floating ice cube with a red core inside of it. The only vulnerable spot on this boss is its bottom side; hitting it anywhere else does no damage. Whenever you hit Icebox's weak spot, a small piece of ice is chipped away, but in response Icebox will shoot an ice bolt at you that freezes the paddle if it gets hit. At half health, the bottom half of the boss will break away completely and from then on you can only damage Icebox by hitting its core. Also, Icebox will try to dodge the ball.
