*Casually shooting out the watermelon seeds at his captain's head*
“This means war!!” he squinted his eyes and gave a highly judging look at his green haired friend after discovering that he has been fired with some watermelon seeds. Whatever the reason for the surprise was Luffy didn’t want to let the culprit go off easily.
So the captain ran to the kitchen and noticed a big bowl of peeled tangerines on the table. Within a minute he shoved all of them to his mouth, started chewing them and climbed to the mast so he could find where Zoro is. After locating the target he could finally fulfill the sweet revenge.
“Gomu gomu no PAYBACK TIME!!” he yelled before shooting out the tangerine seeds at swordsman’s direction.
