Hint: The Flash: Surprise attack:
When you are fighting an opponent and are close enough to jab him or her, press Toward while tapping Light Punch. Flash will move and jab at the same time, which will surprise our opponent. The opponent should have stars quickly, unless the CPU or player catches on. Note: Each tap should be timed and not hit at a rapid pace (which would instead cause Flash to do his Furious Flurries).
