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. If this is not done, less damage will be dealt, this item is useless on spiked foes because the brothers will take damage as they land.
