With Luigi as the rear brother and selecting the move using {{button|gba|L}} and {{button|gba|R}}, pressing {{button|gba|B}} will make Luigi jump on top of Mario, continuously bouncing on him. Pressing {{button|gba|b}} again while this happens will cause the two brothers to jump high into the air, reaching higher places that are otherwise impossible to reach with a normal jump. To cancel the move, the player must press {{button|gba|A}} while Luigi is bouncing on top of Mario. When Mario [[Pump Mario|fills himself up with water]], Luigi can use High Jump to make him spit out all the water in him, which can be used to activate fan-like devices that produce [[Coins]] and [[Mushroom]]s. It is used more than the Spin Jump in the game. The in-battle equivalent to this move is the [[Bounce Bros.]] [[Bros. Attack]].

When Mario [[Pump Mario|fills himself up with water]], Luigi can use High Jump to make him spit out all the water in him, which can be used to activate fan-like devices that produce [[coins]] and [[mushroom]]s. Also, when Mario is made smaller via the [[Mini-Mario]] move and Luigi attempts to High Jump onto him, making Mario jump when Luigi is directly above will cause him to hit him, producing a coin with each hit, though it causes Luigi to lose [[Heart Point|HP]]. This stops when Luigi reaches low enough health. The in-battle equivalent to this move is the [[Bounce Bros.]] [[Bros. Attack]].
In the remake, because the player cannot switch between the bros manually, the player must select the move using the Touch Screen or by using {{button|3ds|L}} and {{button|3ds|R}}. Other than that, the move functions the same way.
