One Piece Chapter 2, page 9-10: THEY CALL HIM "STRAW HAT LUFFY"

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?

Koby explains his lack of courage: "...I REALLY DON'T NEED IT ANYMORE. I BUILT IT TO ESCAPE FROM THIS PLACE......BUT I DON'T HAVE THE COURAGE TO TRY IT. I GUESS IT'S MY FATE TO BE A CABIN BOY FOR THE REST OF MY LIFE. BUT I ONCE HAD A DIFFERENT DREAM." Luffy asks, "WHY DON'T YOU JUST ESCAPE?" Koby panics, shouting, "N-NO WAY! JUST THINKING ABOUT WHAT ALVIDA WOULD DO TO ME IF SHE CATCHES ME MAKES MY BLADDER WEAK... NOPE NOPE NOPE NOPE NOPE NOPE NOPE NOPE I JUST CAN'T RISK IT..." Koby recalls, "I'LL NEVER FORGET THAT FATEFUL DAY... I JUST WANTED TO GO FISHING......AND I BOARDED A PIRATE SHIP BY MISTAKE. THAT WAS TWO YEARS AGO. IN EXCHANGE FOR MY LIFE, I'VE BEEN WORKING AS THEIR CABIN BOY." Luffy bluntly tells him, "YOU'RE KINDA CLUMSY AND DUMB!" Koby sighs. Luffy adds, "AND YOU'RE GUTLESS TOO. YOU REALLY ARE WORTHLESS!" Koby whimpers, "YOU DON'T HAVE TO BE THAT FRANK... BUT YOU'RE RIGHT. I DON'T HAVE THE GUTS TO FLOAT AROUND AT SEA IN A BARREL LIKE YOU... LUFFY, WHY DID YOU GO TO SEA ANYWAY?" Luffy just laughs, "HA HA HA!
