Disclaimer: I don't own How To Train Your Dragon, and knowing my luck, I probably never will. All rights go to the author of the books, Cressida Cowell, and the company that made the much-loved films and series, Dreamworks. However, I do own Brenna Bloodsword and Starlight the Night Fury, as they are my OCs. This disclaimer will change over time, as I may add more OCs to this story.

A/N: Here's a code I made up for you so this is easier to read.

Bold: Dragons are talking
Italics: Humans are thinking
Bold italics: Dragons are thinking
Underlined: Any language being spoken that isn't either Norse or Dragonese by bilingual/multilingual characters. It will be written like this for humans:

*Language goes here "Insert speech here."

And like this for dragons:

*Language goes here "Insert speech here."

If there isn't a language in front of the speech, assume that they are speaking Norse if they're human and Dragonese if they're dragons. Sorry about giving such a long A/N, but I felt I had to explain this for you.

Starlight woke up early and snuck out of the house. She needed to stretch her wings, get some fresh air, start her day right. It turned out that Toothless had the same idea, and they bumped into each other. "OW!" they yelped.

"Starlight!" Toothless stammered. "What are you doing?"

"What are you doing?" Starlight asked.

"I asked you first," Toothless told her.

"I got out of the house so I could get some fresh air."

"I got out of the house so Hiccup doesn't know who hid the Book of Dragons so he'd go to sleep earlier," Toothless admitted. Starlight was taken aback.

"You tricked him into going to sleep earlier?" Starlight asked. Toothless looked and felt guilty, but then she giggled. "Cool! I always knew that humans were gullible!" Toothless relaxed. He was off the hook.

"I only did it because my human refuses to take care of himself. No sleeping pattern, doesn't eat enough and works far too much for his own good. If he couldn't find the Book of Dragons, he'd have to stop," the male Night Fury rationalized.

"My human's the same way. She works for so long and I have to literally drag her out," Starlight complained. "Apparently, the 'it's for the sake of your health' reason doesn't count."

"I shall never understand them, but I won't have to since stopping them is so easy," Toothless bragged. "If I want Hiccup out of the forge, I can easily drag him out. He can't compete physically, but he doesn't remember until it's too late." The conversation would have continued past that point, but that was when they heard a yell.

"Hey, who put the Book of Dragons on the top shelf? Dad, did you - TOOTHLESS!" Hiccup screamed. The two Night Furies looked at each other and giggled.

"You do know, of course, that now I'll have to best you in the sport of pranking the village nerds," Starlight told him.

"Bring it!" Toothless grinned. And it was on.

It started in the arena, with yet another speed lecture. Hiccup, Brenna were enthralled by the rush of information, but everyone else was bored out of their minds. Even Fishlegs was beginning to look disinterested. Suddenly, they started to giggle, and outright laugh out loud. Both nerds were confused.

"What's so funny?" Brenna asked. "This is a perfectly normal lecture about how Monstrous Nightmares generate their fire!"

"Not the way Starlight tells it!" Astrid giggled. The blonde warrior was slowly beginning to lose her distrust about the new girl and her Night Fury. She was actually pretty cool and funny . . . and maybe Brenna was a decent person too underneath all the boundary issues.

"What do you mean, not the way . . . ohhh," Brenna sighed, as she saw Starlight mimicking her actions literally behind her back. "STARLIGHT!"

*Norse "Sorry, Brenna, but I've got something to prove!" Starlight teased.

"Is the thing you have to prove your immaturity?" Brenna asked.

*Norse "I have a bet with Toothless that I can mess with you more than he could mess with his rider and I'm currently winning!" Starlight explained, grinning.

"Don't claim victory yet, Starlight, this isn't over," Toothless sighed. Brenna and Hiccup became rather worried.

"This is rather worrying. I'll have to warn Toothless' rider about this," Hiccup muttered. Brenna facepalmed.

"You are Toothless' rider," Brenna pointed out.

"Oh, yeah." Starlight and Toothless thought this was nothing short of hilarious, and rolled around on the floor laughing. "Anyway, I'll have to go through the contents of the forge so Toothless can't use it to prank me." He walked out of the arena and was met with a barrel of cold water right on his head. "AAARGH! TOOTHLESS!"

"For Thor's sake, Hiccup, this is ridiculous!" Brenna sighed, going outside to get Hiccup back inside. "How would Toothless be able to use the things in the forge? He doesn't even have-" She was cut off by a second barrel of cold water right on her head. "-opposable thumbs." Starlight and Toothless were in hysterics at the sight. "STARLIGHT!"

"This. Is. Priceless!" Starlight shrieked.

"We should mess with them even more!" Toothless declared.

"Am I the only one that's thinking this will be a long day?" Brenna asked, pushing a lock of wet hair out of her face as the other teenagers and all of the dragons howled with laughter at the two drenched dorks.

"For some reason, no," Hiccup replied.

That day turned into an array of pranks aimed at the two teens. Toothless set Hiccup on fire while he was working in the forge. Starlight periodically tripped Brenna with her tail. The piece de resistance came when the Night Furies did the unthinkable: stole their rider's prosthetic legs and played keep-away with it.

"Come on, Starlight, give it back! It's mine and I need it!" Brenna pleaded.

"For Thor's sake, this is just mean!" Hiccup pleaded. Meanwhile, Starlight and Toothless were messing with the spare legs of their riders.

*Norse "Don't be such a baby; we're barely three feet from you. Just get up and walk," Starlight taunted.

"You expect me to walk when you have my leg? Starlight, you are an insufferable jerk of a dragon," Brenna snapped.

*Norse "Aww, Brenna, I love you too," Starlight teased. Toothless was having a ball taunting Hiccup with what he couldn't have.

"Toothless, hand it over! Please!" Hiccup begged.

"No. You've been working far too much and if you can't walk, you can't work," Toothless rationalized. Suddenly, he had an idea about how to torture their nerdy riders so much more. He dropped the prosthetic somewhere out of reach and whispered in Starlight's ear, low enough for Brenna to not hear it and warn Hiccup, but loud enough for him not to have to repeat himself. Starlight grinned when she heard it; Toothless was just full of pranking ideas today.

"Oh, this is good. In fact, this is amazing!" Starlight complimented. Toothless had an impish grin on his face. On humans, it looked mischievous, but on Night Furies, it looked utterly terrifying. "Let's do it!" The two dragged Hiccup and Brenna away from the village and towards the cove, their respective riders struggling and protesting all the way.

"Starlight, get off me! Where are you two taking us?" Brenna asked.

"Toothless, this can be resolved peacefully . . . right?" Hiccup gulped.

"Wrong. You two need to take a break and lighten up," Toothless told him. Despite not knowing what his dragon had said, Hiccup stayed quiet for the rest of the journey. He had a feeling that Toothless wasn't playing around.

*Dragonese "How long is this break supposed to be?" Brenna asked.

*Norse "For as long as you need," Starlight simply said. This sent a chill down the dorks' spines. They were going to be there for a while. Suddenly, Hiccup and Brenna had their shoes taken from them, which were unceremoniously hurled into a corner of the cove. They were now barefoot.

"What could you possibly want with our shoes?" they blurted out.

"It's part of your break," Starlight explained. Toothless began to snuggle close to Hiccup, snuggling his torso in particular. Hiccup squirmed and giggled, embarrassed that Brenna was witnessing his humiliation. Starlight's claws traced Brenna's ribcage, enticing a ticklish squeak out of her. Then they realized, too late, what their Night Furies were about to do.

"Ohhh, Thor," they moaned, just before the Night Furies pounced.

"Ahahahahahahahahahahahaha!" Hiccup howled, as Toothless blew raspberries all over his stomach. "Off, off, off!"

"Starlihihihihihihight, stohohohohop thahahahahat!" Brenna snickered, as Starlight tickled her ribs with dulled claws.

*Norse "But you look so happy. You're even laughing! Why would you want it to stop?" Starlight taunted.

"IHIHIHIHIHIHIHIHIT TIHIHIHICKLES!" the two pleaded, their faces turning red with laughter. Brenna tried to get away, but then Starlight pinned her down to give her more torturous tickles. Her laughter rang throughout the cove.

"Hey, I have an idea. How about we go for their feet next?" Toothless suggested. Starlight grinned. "I've done it to Hiccup before, and he goes nuts."

"Brenna has it bad there, too," Starlight admitted. "But I want them to be too tired to think before we go there." Brenna could understand them perfectly and tried to warn Hiccup, but she was laughing too hard. Tears rolled down both the nerds' faces as they screamed with ticklish hysteria. Neither of the two geeky Night Fury riders were able to move for laughing too hard. Suddenly, they felt tailfins gliding up and down the soles of the one foot that they each had and they let out screeches of laughter.

"GAAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA!" Hiccup laughed, a fist pounding on the earth floor of the cove.

"NOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHO!" Brenna screamed, her face turning red with exertion and embarrassment.

"Daww, aren't they cute?" Starlight cooed, unintentionally giving Brenna a rare break to breathe. Toothless nodded.

"Who knew that nerds were this ticklish? I would have exploited this so much if I knew this earlier," Toothless remarked.

"Who says you can't? We live with them, remember?" Starlight pointed out, and both Night Furies grinned. A chill went down both riders' spines, despite the fact that only one of them understood what they were saying. "Let's take them home." Toothless and Starlight picked up Hiccup and Brenna and carried them home, taking back alleys to not be seen by anyone. Once the two got home, the torture continued. Starlight had her own ticklish way with Brenna quite easily, considering that they lived alone with each other. But Toothless had it harder, since Stoick lived with them and would separate them if they were too loud, and he almost did. Unfortunately for Hiccup, Toothless was far too good at covering his tracks.

"What are you doing up there?" Stoick snapped, barging into Hiccup's room to find that Toothless was tickle-torturing his son. But that wasn't what Stoick saw. He saw Hiccup losing a wrestling match with a dragon. "Ah, you're wrestling, eh? Good to know you have normal hobbies, son. As you were." And then Stoick left.

"Wait, what?" Hiccup yelped, before being subjected to more torture by Toothless, who now knew that he had to keep Hiccup quiet somehow. So he started snuggling Hiccup very closely, with plenty of tickles on body parts Stoick wouldn't be able to see. Like the tailfin doing a serious number on Hiccup's torso or the claws working their way up and down his sides.

There were going to be two nerds on Berk that wouldn't be getting much sleep that night.
