Zoro was lying next to the warm oven while Sanji lit up another smoke. The rest of the crew had received their food, so Sanji sat and relaxed in the quiet of his sanctuary.

Zoro's mind was back to normal for the moment. Sanji had given him a bowl filled with booze as an apology and all had been forgiven. Zoro actually didn't mind the dog business so much. He found it a lot easier to get comfortable on the floor in his new form, plus he got the benefit of the warmest spots on the ship.

"So..." Sanji started, "How is it...being a dog."

Zoro yawned and stretched. His tongue lolled, signaling that Zoro's human mind had vacated the empty hollow he called a head. Or at least, that was how Sanji put it.

Sanji got down on the ground next to Zoro and started to pet him. It wasn't a surprise that Robin did it so much; his hair was silky soft and practically irresistible to any normal human being. Zoro jumped on Sanji, knocking him over. Zoro was now standing over Sanji, with his front paws on Sanji's chest. He licked all over Sanji's face, making Sanji blush.

"O-Oi, Zoro! Cut it out!" Sanji pushed Zoro off and stood up. Zoro's ears went back in a loving way. Sanji had evidently been forgiven for the whole incident, or it had been forgotten all together, which wouldn't have been surprising.

Then, Sanji heard Luffy call from the deck, ruining the moment, "SANJI! DINNER!"

----------------

After Dinner

----------------

"Thank you Sanji, it was delicious," The girls said in unison. The boys noisily vacated the kitchen to play with a now, fully transformed Zoro. He was a green Pit-bull with a very loving personality, which was a complete 180 from Zoro's usual nonchalant behavior. His clothes had been shed, and (Sanji blushed at the thought) was running around in the bare.

Chopper walked up beside him and commented more to himself than anything, "Well, it seems I need to make a few alterations to the serum. Sanji, will you be my next test subject?"

Sanji looked down at the tiny doctor and released the smoke form his lungs, "Fuck, no." And he inhaled another deadly waft of smoke.

"Hmm, I'm sure you'll change your mind." And with that Chopper trotted off to do research on his gene altering solution.

"Like hell I'll change my mind." It was then that the younger men, chased by Zoro, came barreling towards Sanji. Sanji was thrown into the fray and pounced by an excited Zoro. He was panting and jumping about and barking, trying to get Sanji to play with him.

Eventually, Sanji caved and started playing with the ship's new pet. It was better than being bored, and besides...he needed the exercise.

He ran and Zoro chased enthusiastically, and then the tables would turn and Sanji would chase after Zoro. They played a version of hide and seek where the goal of the game was to try to get Zoro as flustered as possible. Then, they'd all rush him and hug him and shower him with affection, even Sanji took part in the pitying part of the game. Zoro would return their love with slobbery licks and happy yips.

Sanji continued to play the game of chase even after the other men had gone off to bed. Eventually, Zoro got tired and wouldn't chase after Sanji anymore. Sanji had to admit, dog Zoro was a lot more fun. He sat down next to Zoro and leaned up against the mast. Zoro crawled closer and put his head on Sanji's legs. Sanji was surprised at the display of affection, but petted his head between the ears and rubbed his back. In no time, the pair had fallen into a light sleep, that is, until an unseen enemy drew near.

Zoro's ears perked and he lifted his head up. Sanji stirred at the loss of the warmth.

"Nnn...Zrro? Wha's wrong?" Sanji slurred. Zoro stood up and arched his back. His fir started to stand up and a low growl was emitting from his throat. He was facing what looked like nothing in particular, but Sanji knew this was not the case. Animals had a sixth sense of sorts, and Sanji was smarter than to ignore it.

"CHOPPER!" He bellowed. Chopper came scampering out of the men's quarters half asleep.

"Whas a matter Snji?"

"There's something up with Zoro." Zoro started to bark.

Chopper nodded at different intervals until he flipped out completely, "AN ENEMY SHIP IS GONNA TRY TO SINK US FROM UNDERNEATH!!! WHAAA!!!"

"What!?" Sanji ran down to the men's quarters. "OI! EVERYONE! WAKE-UP! ENEMY!"

"What!?" Luffy was the first one to wake up and clamor upstairs. The rest were quick to follow, but then Luffy ran back downstairs, "SANJI YOU LIAR! I don't see anything!"

"THEY'RE UNDERWATER YOU MORON!" Sanji was about to elaborate on the situation, but he could already hear wood snapping. "Hurry!"

Enemy pirates jumped out of the water and landed on the deck of the Merry. It wasn't until he heard barking that he remembered that Zoro was still on deck, alone and defenseless. Sanji ran upstairs to find Zoro cornered and looking scared for his life, but he was still trying to defend himself. One guy had severe bite marks on his left leg and another on his corresponding arm. The pirates all rushed him at once, but were deflected by a strange surge of power. A bright flash of light blinded Sanji so he didn't see the transformation, but Zoro had turned into a half man half beast thing. He had his inhuman muscles and big hand, but they had claws instead of nails. And his face was still that of a dog, as were his hind legs.

"Zoro!" Sanji called, but Zoro didn't hear him. Chopper's serum was having unexpected results. It appeared that when Zoro was feeling severely threatened, his body morphed into a form that was neither man nor beats, but a vicious fighting machine.

In the blink of an eye, Zoro defeated the 20 some pirates that were occupying the ship, and then dove into the sea. Within a minute, a tattered submarine went flying through the air. Zoro had just defeated an entire underwater vessel carrying approximately 400 men.

The rest of the crew had finally gotten ready for a fight, but found themselves just standing on the deck observing the miracle. Zoro broke the surface of the water and promptly passed out.

"ZORO!" Sanji dove in after the hero and brought him back to the surface. The two were pulled up on deck thanks to Robins many helping hands. Then Zoro started to shrink back to a normal size, but something was off. He was human again!

"Chopper, why has this happened?" Robin asked, genuinely curious.

"I'm not sure. Perhaps it's Zoro's consciousness that supports his transformation."

Sanji was still supporting Zoro by putting one of Zoro' arms around his own shoulder and a hand on Zoro's hip.

"Sanji, could you take Zoro downstairs, he needs to rest.

"I don't think that's such a good idea chopper, we still need to fix the downstairs before it bursts open and we sink." Usopp said with alarming calmness.

"AHHHH!!!!" The tiny doctor screamed and ran downstairs. Usopp, regaining his normal panicky attitude ran after the doctor with Luffy in tow. You could hear hammering and shouting over the crash of the waves. As the afternoon wore on, Sanji hadn't been allowed to leave Zoro's side. He was assigned to be the caretaker of the unconscious swordsman. From time to time, Sanji would check for a pulse and then go back to reading a book Robin had brought him.

Suddenly, Zoro sneezed. Scaring Sanji out of his calm state of mind.

"Oi, Zoro, don't scare me like that!" Then, soft snores started emitting from the swordsman. Sanji stared to relax, and reached to rub Zoro's head. He petted the swordsman until he heard sniggering behind him. It was only then that he realized what he had been doing and blushed profusely. He stammered, trying to think of en excuse, but Usopp wasn't being convinced.

"Oi, Chopper!" He called out to the doctor so he could share the hilarity of the situation. Sanji didn't think it was very funny. He was worried about the swordsman (not that he'd ever admit it) and he needed some way to help comfort the swordsman as well as himself.
