Alexzandeia requested WW Luffy + Zoro during a lunar eclipse, and they . . . well, you'll see. A solar eclipse was also mentioned/suggested, but that has a different effect, so I think I'll save that for another chapter.

Non-humans: WW Luffy, WW Zoro

On the morning of the full moon, the crew (except for their two resident werewolves) was gathered around the table for breakfast.

As Sanji served up hash browns, Nami said, "I just remembered, there's going to be a lunar eclipse tonight."

"What time?" Robin asked, her eyes lighting up.

"I think it starts at two," Nami said slowly, trying to remember, "And ends around . . . five. I'm not sure how long the total eclipse lasts . . ."

"I'll take watch tonight," Robin volunteered quickly. She looked around. "Would anyone like to join?"

"I'll join you, Robin-chwan!" Sanji cried.

"Chopper-san and I are staying up anyway," Brook said.

"I'll pass," Franky said.

"Sure," Usopp said. "I've never seen a lunar eclipse . . ."

Sanji scowled. "Damn long-nose, ruining the romantic mood," he muttered under his breath.

Chopper looked around. "Um, what's a lunar eclipse?"

"Well, the world orbits the sun," Robin explained. "And the moon orbits the world. The moon has phases like crescents and new moons because of the shadow cast by the planet. Sometimes, if the conditions are right, the moon, world, and sun line up just right for the planet to cast a special shadow on the moon. First the moon becomes dim, and then for a period of time it becomes blood-red. After that it becomes dim again and then bright when the eclipse is over."

"Oh," Chopper said in understanding. "Wow, that sounds awesome!"

Robin nodded. "When people first saw lunar eclipses, they thought it was an omen of bad things. Imagine if you didn't know about things like that, and that bright white moon in the sky suddenly turned blood-red one night . . ."

Chopper nodded with sparkling eyes. "I'm glad I get to see it, then!"

"Oh, and a solar eclipse is almost the same thing," Robin continued, smiling. "It always happens during the new moon after a lunar eclipse. The moon passes between our planet and our sun, and it blocks out the sunlight like a big black disk in the sky."

Chopper's eyes grew even rounder and sparkly with wonder.

"You're going to overexcite him," Usopp scolded teasingly.

"I've never seen an eclipse in person," Robin sighed. "I've only read about them . . ."

Nami cleared her throat. "Robin, Sanji, Usopp, I'll join you guys tonight."

"Yes!" Sanji exclaimed happily.

"Alright," Usopp exclaimed.

Sanji scowled at Usopp again.

"A what ellipse?" Luffy asked. He and Zoro had just gotten out onto deck. As usual, they were suffering from headaches, stomachaches, a fever-like temperature, and prickling skin.

Brook explained the phenomena quickly in layman's terms as Robin, Nami, Sanji, and Usopp climbed up to the observation deck.

"Oh, so the moon's gonna be red," Luffy said in understanding. He yawned and grinned. "Neato."

"Whatever," Zoro muttered. "Luffy, c'mon."

Chopper and Brook, as always, went behind the mast out of politeness as the werewolves quickly stripped.

When they heard the clicking of nails on the deck, they came around and met up with their friends.

Hi, Luffy exclaimed, trotting in circles. Are we playing fetch?

"Do we have a stick?" Brook asked Chopper. "I think we forgot to get a stick."

Zoro growled in disappointment.

"Maybe you could detach one of your arms?" Chopper suggested.

Brook's jaw fell open in utter shock. "Chopper-san!" he exclaimed indignantly. "Why—that's ludicrous!"

"But you could attach it right back, right?" Chopper asked innocently.

Brook straightened up in a dignified way. "It doesn't matter who it is, I do not want anyone to chew on these bones of mine! Apologies to Luffy-san and Zoro-san, but I'd rather not have teeth marks all over my radius and ulna!"

Chopper raised his hooves. "Okay, okay, I see your point."

Up in the crow's nest, Nami shouted something and a bonk was heard, as if something had been thrown at someone's head. Luffy and Zoro looked up and growled.

"Try to keep it down, you four!" Brook called up.

In the wee hours, just as Nami had said earlier, a shadow began creeping across the moon.

"Wow," Chopper whispered, watching the dark curve move slowly across the face.

"I haven't seen one of these in many years," Brook murmured, staring up at the sky with Chopper and the werewolves. "But then again, it's hard to see anything with no eyes . . ."

Zoro and Luffy suddenly started to whine in distress.

"Guys?" Chopper asked in alarm, looking at them. "What's wrong?"

Something's—happening— Luffy growled, wincing.

Head hurts— Zoro growled.

They whined for a moment more before collapsing onto the deck. Chopper checked them over, but it seemed they were only unconscious.

They stirred and Chopper jumped back as they stood. The werewolves looked around in surprise.

Chopper? Luffy said. What's going on?

"What do you mean?" Chopper asked confusedly. "You guys collapsed a minute ago."

No, why are we like this? Zoro demanded, turning around in a circle.

"Like . . . what?" Chopper asked.

Why do we know what's going on and stuff? Luffy attempted to clarify.

"Er . . . Chopper-san, is everything okay?" Brook asked.

Chopper shrugged. "They're asking why they're like this and what's going on."

Oh, yeah, I guess Brook can't understand us, Luffy sighed.

"No, he—what are you two talking about?" Chopper asked, frustrated.

We're lucid, Zoro said. We have our human minds right now.

"What—really?!" Chopper squeaked in surprise.

Luffy nodded. This is really weird. Is it because of the lunatic eclipse?

"Lunar," Chopper reminded him. "Maybe?"

He turned to Brook and explained what was happening.

"Oh, my, this is unprecedented," Brook remarked.

Oh! The others are up there, right? Luffy asked, circling himself excitedly with a wagging tail. Can we see them?

Just as he said this, an arm appeared from Brook's torso. He shrieked in surprise.

Robin's arm bore an ear, an eye, and a mouth. As they stared at it, it swiveled around and looked at them all.

"Sanji wanted to get into the kitchen and get food and drink," the mouth said, speaking jerkily (Robin was apparently not used to communicating like this). "Is there any way to do this?"

"Yeah, actually . . ." Chopper explained the situation.

The limb, with its accessories, vanished suddenly. In the next moment, Robin herself floated down from the crow's nest, carried by a chain of hands.

"Good morning," she said. She looked at Luffy and Zoro, who made no move to attack and were instead looking at her like a friend. She smiled. "You two really are lucid?"

Luffy let out a happy bark and ran up to Robin. She let him sniff her hand before she started petting his head. He pushed into her hand happily while Zoro sat stiffly off to the side.

"Is it safe?" Usopp called from the crow's nest in a whisper-yell.

"Come on down," Robin said. Behind her, a ladder of arms appeared, and Usopp, Sanji, and Nami used them to climb down.

"Are you sure they won't attack?" Nami asked nervously.

If you don't want to be here, go back up, Zoro growled irritably. Chopper translated.

Usopp, Luffy exclaimed, bounding over to his friend. Usopp nervously let Luffy sniff his hand and, when he flopped onto the deck, started giving him a belly-rub. Luffy's tail thumped happily on the deck.

"You guys are pretty cute as wolves," Usopp said, grinning.

Zoro growled faintly.

"Oh, don't be like that, moss-head wolf-boy," Sanji muttered. Zoro's ears went back and he growled louder at Sanji, who backed up a step automatically.

"Right, I'll get us some snacks," Sanji said. He hurried into the kitchen.

"Is this caused by the eclipse?" Robin wondered aloud, looking up at the blood-red moon.

"Must be," Nami said, petting Zoro gently as he sat stoically and pretended to ignore it. "I wonder what would happen during a solar eclipse?"

"Hopefully nothing," Usopp said as he hugged Luffy around the neck. "Solar eclipses happen during the new moon, right?"

"Right," Robin said. "Still . . ."

Sanji pushed open the door with snacks—hot cocoa and sandwiches for himself, Brook, Nami, Robin, Usopp, and Chopper; and two platters of nearly raw meat for the werewolves.

Everyone perked up at the sight of the food.

"Dig in," Sanji said.

The eight of them stayed out on deck for the entirety of the eclipse. Just before the dark shadow on the moon vanished completely, Luffy and Zoro whined and winced and collapsed again.

"Aah!" Chopper yelled. "Guys, clear out! They must be going back to wolves!"

The other four scattered to their rooms. A moment later Luffy and Zoro rose again.

What happened? Zoro growled. He sniffed the air and snarled. Why do I smell humans?

Chopper sighed in disappointment as Luffy growled too. "You guys were unconscious for a bit. Some humans came by while you were out."

Luffy growled angrily.

"You guys got to party with Strawhat and Bro Zoro when they were wolves and you didn't wake me up?!"

"You were sleeping," Sanji said, yawning.

Franky groaned. "I coulda made that party, man!"

"We had a good enough time on our own," Nami muttered.

Franky slumped in his chair. "I'm just not feeling it this week . . ."
