A battle of limits. Luffy and the infinite biscuits:
Back to the fight against Cracker, Nami's strategy is to create a cloud of rain to soften the "Biscuit Soldiers" so Luffy can destroy them easily. However, these don't stop regenerating, so Luffy chooses to eat them to make them disappear once and for all. Unfortunately, Cracker is able to create new "Biscuit Soldiers" with ease. The fight ends up turning into a duel between the Cracker's ability and Luffy's insatiable stomach.
