When the attack is initiated, Mario and Luigi appear in a Japanese style dojo with a line of Paper Mario copies to the left and right of them (the amount depends on how many active copies Paper Mario had before the attack started). Their enemies will now then start falling down the screen, with the Mario Bros using a crosshair to aim and fire shurikens at them (with for Mario and for Luigi). The player can also press as the shuriken approaches the enemy to make Paper Mario attack it with more power.
If the Mario Bros. hit six enemies with shurikens, the Paper Mario copies will form into a giant shuriken that Luigi grabs hold of. At this point, any remaining enemies will start falling down the screen en masse, and the final shuriken can be thrown at them to take them out. Hitting at least one enemy with this shuriken will give the player an excellent rating and blast down the back wall of the dojo, revealing a night scene with a large full moon and hills. Mario or Luigi can only lock onto one enemy (or segment of an enemy) with the large shuriken, and cannot choose a different enemy after locking on, so they must wait until as many falling pieces of paper are within the shuriken's range before firing. There is always a pivotal moment where all pieces of paper merge together, meaning it isn't too challenging to hit all enemies at once.
Striking one, three and five enemies in the initial stage of the attack will yield an "OK", "Good" and "Great" rating respectively. The amount of times is pressed does not affect the "Excellent" rating, despite it causing a considerable difference in damage caused.
