A/N: I find myself missing random Straw Hat moments, so why not create them? I will be writing more, though I can't say how often. Review, please!

Nami came storming onto the deck, her glare fearsome enough to make Chopper hide behind Robin's legs.

"Where is Luffy?" the navigator asked, her tone soft but deadly.

"Oh, Nami!" Luffy exclaimed, popping up from behind Zoro's chair. "Were you looking for me?"

She walked over to her captain slowly. There was seemingly nothing threatening in her demeanor but Zoro knew better; he hurriedly went over to calm down the shaking Chopper.

"Luffy, how could you ruin another map?" Nami raged, her mood suddenly darkening. "I worked on that for one week and in one second, your stupid peach juice ruined it completely."

"Heh, sorry," Luffy apologized.

He reached up to scratch his head. The innocent gesture didn't get him any sympathy from Nami. Her punch sent him flying into the side of the ship. Luffy sighed as he landed with a loud thump.

"Nami, I said I was sorry," he reminded her.

"Idiot," she muttered.

With that, she turned to make her way back to her room to start making the map all over again.

"Excuse me, dear lady."

Nami rolled her eyes and turned to Brook, her arms folded over her chest.

"What is it?" she asked.

"I need a favor," Brook told her.

Nami tried to take caution in making her decision but it didn't work out too well. She nodded, giving him a cue to go on.

"I need to see your panties," Brook said seriously. "The ones you are wearing now."

She let out something between a snarl and a growl before going into her room and slamming the door, not even bothering to dignify Brook's request with a response.

Zoro scowled; he'd have to deal with the scared Chopper for the rest of the day now.

"Why is she like that?" Chopper queried quietly. "The rest of us didn't do anything wrong."

Robin gently patted him on the head.

"You should know, as a doctor," she pointed out. "You've heard of PMS, I assume?"

"Do you mean PERMANENT MACHO SUPANESS?" Franky yelled, running over in excitement.

Zoro wanted to ask him if he was serious but decided against it.

"No, she means probably the most scary," Zoro explained. "It's a woman thing."

"Wouldn't that be PTMS?" Chopper asked, confused.

Robin smiled and shook her head.

"He's not telling you the right thing," she chuckled. "But be sure to look it up sometime."

"Yeah, I will!" Chopper agreed, nodding enthusiastically.

"And, Zoro," Robin began.

She stopped talking when she realized that Zoro and Usopp were having a serious talk about what they should shoot at Nami through her window. Trying to hide her amusement, Robin cleared her throat loudly.

The two looked up from their intense discussion. Usopp was apprehensive; the beads of sweat would surely start rolling down his face if Robin said anything about their plan. Zoro was impassive, just waiting for her to say whatever she wanted to say.

"I would recommend nothing sharp," Robin said finally.

She was right. A drop of sweat ran down the side of Usopp's face almost immediately.

"You're right!" he exclaimed. "But I had already worked that into my great plan, of course. I was just testing Zoro to see if he was paying attention. Obviously, he wasn't, so he must be quite unintelligent. Just like I originally thought…"

"What the hell are you saying?" Zoro grunted, glaring at the younger boy.

"Ahh, nothing!" Usopp protested.

As Zoro pulled out a sword, Usopp started running away, very quickly. The green haired man chased after him, intent on getting revenge for the absentminded remark.

"Oh, are we playing tag?" Luffy asked, excited. "Zoro's it!"

"SUPA!" Franky called. "I'm playing too!"

Chopper bounded over to Luffy, his eyes shining.

"Me too!" he declared. "Everybody, run away from the crazy swordsman!"

"What are you people calling me?" Zoro growled, picking up the pace.

Robin's smile widened and she calmly picked up her book and resumed reading.

"THE NEXT PERSON THAT RUNS INTO MY ROOM IS GETTING ELECTROCUTED!" Nami screamed, more furious than ever.

Brook considered that for a moment.

"Perhaps," he said thoughtfully. "If she electrocutes me, I will end up on the floor and she will end up standing over my fallen body. And then, of course, I will be able to see her panties."

"Perhaps," Robin agreed. "I'm sure Usopp wouldn't mind shooting you through the window."

"Thank you for the tip, beautiful lady," Brook grinned. "You have my eternal gratitude."

Robin eyed him, the smile never leaving her lips.

"I'm not showing you my panties," she told him, her tone suddenly chilling.

Brook immediately went to join the game of tag.

"Usopp!" he called. "I need you to shoot me through the window!"

A few minutes later, Robin smelled burning hair. She was almost worried enough to go check on the skeleton but when she heard the contented sigh, she just smiled.
