Cannonballer

Cannonballers are Bros. Items that cause lots of damage to an enemy. It only appears in Mario & Luigi: Partners in Time. It can only be used to attack one enemy. Mario, Luigi, Baby Mario, and Baby Luigi must be available to use this item. The four heroes jump into a cannon which shoots them out in a random order; they then land on the same foe one at a time. The player must press each brother's selected button right when they are about to hit the enemy, or else the action command will fail and less damage will be dealt. The Cannonballer is useless against spiked enemies, as they have immunity to jump attacks and will deal damage to the brothers.
