You will hit them in the air. Then keep pressing circle. Then for the final attack add-on, you will hit them up again again Luffy will count down, 3 2 1. then he will yell and twist like a spiral and bounce up and smash your opponent throught the roof of the building.

Note: this trick works well with over four fruits and if your opponent health is down a little bit past halfway.
