'''Yoo Who Cannon''' is a [[Bros. Attack]] that appears in ''[[Mario & Luigi: Bowser's Inside Story]]'', its remake ''[[Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey]]'', and ''[[Mario & Luigi: Brothership]]''. It is automatically gained upon completing the [[Koopa Paratroopa Trio]]'s tutorial with the [[shell block]]. A part of its name is a pun on the interjection "yoohoo" and the word "who". It costs seven [[Bros. Point|SP]] to use this attack in ''Bowser's Inside Story'', fourteen/sixteen BP in its remake, and 12 BP in ''Brothership''.

When using this attack, [[Mario]] and [[Luigi]] will briefly appear in eight [[Barrel Cannon]]s on screen; the player has to remember where they are. After a barrel rises, the player has to press the {{button|ds|A}} or {{button|ds|B}} button, depending on which brother was sitting there but, the player has to press that button before the fuse reaches the barrel to damage the enemy. If the wrong button is pressed or if the player takes too long, the other barrels will be destroyed, and the move will prematurely end with little damage being dealt. After teaching Mario how to use [[Blue Shell]]s, the [[Koopa Paratroopa Trio]] will give him and Luigi an [[Attack Piece Block]] which houses the 10 [[Attack Piece]]s required to use this move. In the remake, Yoo Who Cannons now aim at the enemy to hit upon being used.

It, [[Green Shell#Mario & Luigi series|Green Shell]], [[Mighty Meteor]] and [[Snack Basket]] are the only Special Attacks that are mandatory to complete the game.

This move is available for use in the [[Challenge Node]]. It becomes trickier when remembering the order becomes shorter.

Yoo Who Cannon [[List of Mario & Luigi: Dream Team pre-release and unused content|was originally going to appear]] in ''[[Mario & Luigi: Dream Team]]'', but was scrapped from the final version.<ref>https://www.spriters-resource.com/3ds/marioluigidreamteam/sheet/63828/</ref>

Yoo Who Cannon returns in ''[[Mario & Luigi: Brothership]]'' as a Luigi-exclusive Bros. Attack, and now involves placing an additional, massive cannon behind the enemy ranks to catch the fired brothers, unleashing all eight as a giant bowling ball and dealing damage to all enemies if an "Excellent" is achieved (similar to the [[Toad Trail]] finisher); firing at the wrong time will cause the barrel to explode and the Bros. and copies to spill out; additionally, said copies vanish harmlessly while the real Mario Bros. head back to their spots.
