Yeah... here's more.
"And there was so much food! All the good kind of fattening food, and I began to eat it all!" Usopp yelled and made wild hand gestures as he described his story from the Boin Archipelago.
"Sugoi Usopp!" Chopper drooled slightly, thinking of all the food. "How did you not get fat?" he asked.
"Um! Well, I... uh..." Usopp began sweating lightly. "W-what's for dinner Sanji?!" He turned his head and called loudly for the cook.
"Shut your mouth! It'll be ready when it's ready," Sanji replied rudely from inside the kitchen.
"Anyways," Usopp turned back to his group that he was telling the story to. Chopper was looking at him intently, while Luffy laid motionless on the grass. "Luffy, are you okay?" Usopp asked worriedly. Usually Luffy would be really into his stories and would have interrupted him several times. But while Usopp was talking, Luffy had just been laying there, almost indifferent to the whole conversation.
"I'm fine," came the automatic answer. Luffy didn't even turn his head to speak.
Usopp exchanged a nervous glance with Chopper. Neither knew what was wrong with Luffy.
