Long Summary
Law, Luffy and the other pets are imprisoned next to Caesar. Breed gives a command to Caesar over a Den Den Mushi, but Caesar does not react to the command the first time, as he does not hear it. Breed thinks of Chopper as a cute pet, and decides to dress him up as a princess. Chopper is infuriated at this costume, and scratches Breed. Angered, Breed whips Chopper, enraging Luffy and causing him to insult Breed. Breed, enraged as well, decides to put up the "greatest show on Earth", and makes Luffy and Law battle to the death. The Kung Fu Dugong gets very upset and tries to stop Breed's calamity, but is also whipped by him. Breed gets even more angry, so he decides to force the Dugong himself to beat Luffy and Law to death. Luffy is patient, and tells the sad Dugong that nothing will happen to them. Dugong strikes Law and Luffy with a punch, and they fall through the glass wall into the water.
