When used, the player launches three rubber balls that go in almost 18 degrees separated from the other and change their direction after colliding with walls and some enemies. If they have bounced for enough time, they explode and drop confetti that falls. The player character can shoot it frontally, diagonally upwards and diagonally downwards. If shot over the floor, the balls will be sent in a close direction as if they were shot diagonally upwards. When a ball collides with an enemy without defeating it, it is bounced as if it has collided with a wall.
There can be no more than two sets of balls. The weapon has 28 uses without recharging.
