Stylish Moves are mainly used to help get the crowd more excited and fill up the Star Meter quicker. However, the Stylish Move must require the right moment in the middle of the attack for it to work. At the moment, the player must press "A" at least once (in other cases most notably the Power Smash requries up to five A buttom presses). Stylish Moves also appear in Super Paper Mario.
