### Summary
As the Straw Hats race towards Arlong Park to save Nami, their advance party is intercepted by one of the fish-man's monstrous beasts. Luffy, Sanji, and Yosaku come face-to-face with Mohmoo, a giant sea cow dispatched to halt their progress. Underestimating the rubber-man's simple-minded ferocity, the beast finds itself on the receiving end of a brutal, yet comical, beatdown that leaves it utterly terrified. With their path now cleared in typical Straw Hat fashion, Luffy proves that nothing, not even a monster from the Grand Line, will stand between him and his navigator.
