One Piece Chapter 20, page 12-16: A Thief's Philosophy

Buggy's hands desperately pull the sack, screaming, "IT'S MY TREASURE!!" Nami holds on tight. Luffy runs forward to intervene, shouting, "I JUST TOLD YOU THAT YOUR OPPONENT..." Buggy's head turns in surprise.

Luffy delivers a powerful kick straight to Buggy's face, shouting, "IS ME!!!" Buggy's head is sent flying backward with an "EHCK!!?" as Nami watches in awe.

Buggy's head and hands are blasted away into the sky. The treasure sack falls to the ground, spilling coins. Luffy lands safely and declares, "BULLS-EYE!!" Nami looks on in silence.

Luffy grins and says, "THAT LAST KICK... WAS FOR THE VILLAGE CHIEF!" Nami thanks him: "THANK YOU. THANKS TO YOU, I'M ALIVE." Luffy laughs it off, "HMMM... DON'T WORRY ABOUT IT." Luffy then remembers the map, while Nami gasps as she notices her treasure scattered everywhere.

Luffy triumphantly holds up a scroll, shouting, "ALRIGHT!! I'VE FINALLY GOT IT. THE 'GRAND LINE' MAP!!" Suddenly, Buggy's tiny chibi-like body (just his head, hands, and feet) appears behind them, yelling, "WAIT...! WAIT, GOMU GOMU KID!! I'LL KILL YOU ONCE AND FOR ALL!! BARA BARA PARTS!!! GATHER UP!!" Luffy turns around in surprise.
