One Piece Chapter 41, page 9: To the Sea

Kaya tells the crew, "I HAD EVERYTHING YOU WOULD NEED FOR A VOYAGE LOADED ON TO THE SHIP." Nami bows gratefully, saying, "THANKS FOR CAUSING ALL THIS TROUBLE!" Zoro quickly corrects her grammar, muttering, "THAT'S 'FOR GOING THROUGH ALL THIS TROUBLE'..." Suddenly, a loud screaming sound echoes from the hill. Everyone turns to see Usopp rolling down the path at extreme speed, trapped inside his giant round backpack. He screams, "STOP ME PLEASE!!!" Kaya gasps, "USOPP-SAN!" while Luffy wonders, "WHAT'S HE DOING?" Zoro calmly observes, "I THINK WE SHOULD STOP HIM... IF HE KEEPS ON GOING LIKE THAT, HE'LL HIT THE SHIP."
