After Luffy's explosive entrance, he is stopped by Arlong's men. But diplomacy is not Luffy's best point, instead he throws a huge punch into the face of their fishman captain. Luffy cannot forgive Arlong for making Nami cry because he still considers her as his navigator. After this declaration of war, the fishmen start to attack Luffy, but they are easily knock out by Sanji who also has entered the place alongside with Zoro and Usopp. Hatchan, pissed after Zoro tricked him, threaten them as the future meal of his pet Mohmoo. But when the giant sea cow appears, it still has the wounds of his previous encounter with Sanji and Zoro. After some blackmail from Arlong, it starts to attack the Straw Hats anyway, but Luffy, thanks to a new attack, blew everyone not worthy away.
