One Piece Chapter 2, page 8-9: THEY CALL HIM "STRAW HAT LUFFY"

Alvida's crewmen point accusingly at Koby, shouting, "UH... CAPTAIN! WE HAVE AN INTRUDER!! YEAH! THAT GOOD FOR NOTHIN' KOBY BROUGHT THAT STRANGE FELLER HERE!" Alvida is suspicious, wondering, "WHAT!? COULD HE BE A BOUNTY HUNTER......AFTER THE PRICE ON MY HEAD? KOBY! YOU TRAITOROUS LITTLE RUNT!" She ponders, "BUT THE ONLY BOUNTY HUNTER BOLD ENOUGH TO COME HERE..." One crewman suggests, "THAT'S RIDICULOUS!! THE NAVY HAS HIM LOCKED UP..." but another counters, "BUT IF HE'S AS CLEVER AS THEY SAY... HE MIGHT'VE ESCAPED!" Alvida grins, "AND THEY SAY THAT THE INFAMOUS RORONOA ZOLO IS THAT CLEVER!!" Meanwhile, in the forest, Koby asks Luffy, "UM... ARE YOU OKAY? ARE YOU HURT? AFTER GETTING KNOCKED AROUND SO MUCH YOU MUST BE--" Luffy laughs, "HAHAHAHA! I'M FINE, JUST A LITTLE SURPRISED IS ALL. MY NAME'S LUFFY! WHERE AM I?

Koby introduces himself: "THIS ISLAND IS THE HIDEOUT OF IRON MACE ALVIDA, THE LADY PIRATE. I'M KOBY, HER CABIN BOY." Luffy responds indifferently, "I SEE... WELL, NONE OF THAT REALLY MATTERS TO ME." Luffy then asks, "YOU WOULDN'T HAPPEN TO HAVE A DINGHY, WOULD YOU? MINE GOT SUCKED INTO A GIANT WHIRLPOOL." Koby is shocked: "YOU GOT SUCKED INTO A GIANT WHIRLPOOL!?" Luffy smiles, "YEAH, IT CAUGHT ME BY SURPRISE!" Koby sighs, "YOU'RE LUCKY TO BE ALIVE!...BUT IF IT'S A DINGHY YOU WANT, I HAVE ONE... SORTA..." Koby leads Luffy to a clearing and shows him a small wooden boat that looks like a coffin. Luffy exclaims, "WHAT'S THIS!? A COFFIN?" Koby explains, "I BUILT IT MYSELF. IT TOOK ME TWO YEARS..." Luffy is amazed, "TWO YEARS!? AND YOU DON'T WANT IT?
