Here's how to do some advanced bros moves. You have to keep using bros moves until mario say advanced or something. i only k now how to do advance moves for splash bros and bounce bros. For splash bros when mario junps on luigi press A and then mario is directly on top of luigi press A again. Mario will jump up and the word Advanced will appear on the screen. press B when mario is on luigi and he will throw mario into the sky and mario will be spinning around and press A when mario will lands on the enemy. This is for bounce bros: press A when luigi jumps above mario and it will say advanced.press B when they land. this will seperate mario and luigi and you press B directly followed by A if you have multiple enemies you can hit two at once. If you want a stronger attack and you dont want to hit two enemies at once you press only A when luigi jumps above mario and that will do the total damage you do the other advanced way of bounce bros.
