Paper Jam Petey Piranha Strat

Petey Piranha:(Assuming you dodge everything)
PM: Jump/Trio Racquet (Trio Racquet only if he is already knocked down) 12/24
Mario: Red Shell/Hammer (Hammer if you used Trio Racquet last turn) 27/30
Luigi: Fire Flower 72/75
Counterattack Petey 75/78
PM: Hammer 82/85
Mario: Red Shell 97/100
Luigi: Fire Flower 142/145
(This assumes 45 each Fire Flower) Add extra special attacks if you need the extra damage from slower mashing. Red shells are a bit faster but you only get 9 extra damage instead of 12 extra with Trio Racquets
