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.

The next morning, Hiccup and Brenna banded together to think of ways to get Toothless and Starlight back for the day of pranks they had been subjected to. "Putting them together was a terrible idea, especially considering my dragon has so much experience with pranks. She must have been the driving force behind it all."

"Don't forget about Toothless in all of this!" Hiccup warned. "Toothless has been an active participant in Loki Day ever since he got here! Once, he tricked Snotlout into locking himself into a dragon cage by telling him that there was yak butter parfait in it for him if he lasted a full day!"

"And Starlight's been planning pranks like this with me since diaper days!" Brenna snapped. "She hid inside a cave and tricked people into thinking the cave was cursed to have an evil spirit live inside it! People were buying each other good luck amulets to protect themselves from the big black demon!" Then a shared realization came across both of them at the same time.

"Wait a minute . . . they can't both be the bad influence . . . can they?" They groaned and put their heads in their hands, looking remarkably similar as they bemoaned their bad luck of introducing a prankster to another prankster.

"Enough moaning, we need a plan of action," Brenna told Hiccup. "A prank that people will honour for generations! What can we use to mess with them?"

"Eels?" Hiccup suggested.

"Not specific enough and too cruel. Bright lights?"

"Wouldn't hurt them and they'd probably enjoy that. Dragon traps?"

"The possibility of innocent bystanders being caught in the middle is too high." The village milquetoasts sighed and watched the Night Furies interact to see if there was any weakness that they could manipulate. And that was when they had a breakthrough.

"And that was when Brenna saw the sword and - EEEK!" Starlight cut herself off with a terrified shriek as she perched on top of an unfortunate person's house. "SPIDER!"

"Holy Thor!" Toothless yelped, stamping on the spider until it was dead. "Starlight, it's fine. The spider's dead now." Starlight slowly came down and nuzzled Toothless gratefully.

"Oh, thank you, Toothless. How did you do it?" Starlight asked.

"I can only do it because I'm bigger. If I wasn't, I would be as scared as you," Toothless admitted. Meanwhile, Brenna translated to Hiccup in the background as the two had devious grins on their faces. Then the two nerds ducked away to the forge. They had a plan to enact.

"What are you two nerds doing?" Astrid asked, after Hiccup and Brenna had spent a total of two hours working in the forge. She didn't like this Brenna girl hanging around with her Hiccup.

"Getting Toothless and Starlight back for yesterday," Hiccup blurted out. Brenna glared at him.

"Keep telling people that and we'll never be able to get them back," she sighed.

"I'm with you two on this one," Astrid said, surprising them. "Toothless and Starlight's pranks seemed funny, but that was when they were only aimed at you. They're taking their pranks around the village."

"What did they do?" Hiccup and Brenna tiredly chorused.

"They locked everyone's dragons inside the arena and hid the key!" Astrid told them.

"You continue with the plan; I'll unlock the dragons," Brenna ordered, as she left for the arena. A bunch of dragons bombarded her with complaints about Toothless and Starlight. Or at least, they bombarded the gates. Every species of dragon that was on Berk was crammed into the arena (every species except the Night Fury, that is). Even Terrible Terrors had fallen for the trap.

"Help! Toothless and Starlight locked us in here! Help!" a male blue Deadly Nadder ordered. Brenna took off her brooch and started picking the lock.

*Dragonese "How did they get all of you in here at once?" Brenna asked. Needless to say, the dragons freaked out.

"Holy Thor, the stupid Terrible Terrors were right for once!"

"We're not as dumb as you think, you know!" a peeved Terrible Terror snapped.

"How does she know this? The language is called Dragonese for a reason!"

"Who taught her?" She ignored them all as she picked the lock with her brooch and let them out.

*Dragonese "Where did they go?" Brenna asked.

"That way!" the dragons chimed, pointing with wings and claws to the forest nearby.

*Dragonese "Thanks," Brenna replied as she moved to let all the dragons leave without being crushed to death in the chaos. She then went back to the forge and reported everything to Hiccup and Astrid.

"Toothless and Starlight had locked them up in the arena and are now hiding in the forest to escape both us and the other dragons," Brenna relayed. "So temporarily, the entire dragon population hates them." A wicked grin spread across Brenna's face. "I think I know of a good way to get ourselves some help and spread the word."

"I'll continue with these plans, then," Hiccup muttered, as Brenna walked away.

"Why do they look like spiders?" Astrid asked.

"Never you mind," Hiccup huffed. Brenna met up with Hookfang, who was very thankful for the release.

"Brenna, thank you so much. Whatever you need, just let me know and I'll get it done," Hookfang promised.

*Dragonese "Oh, you will, will you? Would you mind spreading this message to all the other dragons on Berk?" Brenna asked sweetly.

"Of course I could! What's the message?" Hookfang asked.

*Dragonese "Tell all the other dragons to tell Toothless and Starlight that there's a new breed of extra large spider in Berk, OK?" Brenna instructed.

"Got it!" Hookfang eagerly replied, as he flew off. Brenna returned to the forge, grabbed a few pieces of paper and started scribbling down utter nonsense.

"What the Thor are you writing about?" Hiccup asked.

"The possibly mythical breed of giant grey spiders, if you must know," Brenna replied.

"Those aren't real," Hiccup and Astrid chorused.

"Toothless and Starlight don't know that," Brenna pointed out. Hiccup grinned deviously.

"This is going to be really fun to watch," Astrid noted. "Don't you worry your nerdy little heads about it; my lips are sealed. This is far too fun to blab about." Astrid then walked away, searching for popcorn.

"How do you know that they'll read it?" Hiccup asked.

"Starlight's a snoop and Toothless can read," Brenna analyzed. "Qualities like that will end up in both of them knowing what it says."

"Now this is interesting," Hiccup laughed. "Hey, Brenna, pass me that wrench, will you?"

Meanwhile, the other dragons were fuming about Toothless and Starlight's harmless little prank. "What were those two thinking?" Stormfly fumed. "They know that I hate being locked up in there! And we can't all fit in there!"

"Well, we did," a Terrible Terror stupidly pointed out. A Gronckle smacked him with their paw. "OW!" Hookfang came flying in in a frenzy, panting for air and his scales flaming up.

"Whoa, Hookfang, no need to make an entrance, we all see you!" Barf joked. The other dragons laughed.

"I have a message from Brenna for you," Hookfang panted.

"Who's Brenna?" an old Deadly Nadder asked.

"She got us out of the arena," Meatlug explained. "She spoke Dragonese and asked us where Toothless and Starlight went. She told me to give a message to all of you."

"The helpful human!" one head of an old Zippleback remembered. "Relay the message! She helped us, so we should help her!" The other dragons quickly agreed.

"She told me to tell all of you to tell Toothless and Starlight that there was a new breed of extra large spider in Berk," Hookfang relayed. It was an odd message, and Hookfang knew it. "I don't know why she wanted me to tell you this. It's weird."

"Maybe she has a plan of some kind to mess with those pesky Night Furies," a Monstrous Nightmare suggested.

"Whether she does or doesn't, we should adhere to tradition," an especially old Gronckle declared. "We find the human food called popcorn and we watch what happens while eating it!"

"Yeah!" all the other dragons (minus the Night Furies) cheered.

Toothless and Starlight were giggling at the memory of tricking every dragon in the village into going into the arena and then locking the gate and running away. "You remember their faces?" Toothless laughed.

"Priceless! We should do it again!" Starlight suggested. The two giggled, and eventually laughed. Nobody was there to tell them off. They were free from their nerdy, killjoy humans. They were in charge, not them. As they celebrated, they sniffed the air. Fish. Both Night Furies became very, very hungry. Breakfast was such a long time ago, after all.

"That raw fish smells divine," Toothless sighed, smiling. "And it's . . . in Berk?"

"We'll have to avoid the other dragons. They're still mad at us for the whole 'trapping every dragon inside the arena' thing," Starlight warned. "Maybe our riders will get some for us."

"But what if they're still annoyed about yesterday?" Toothless asked.

"Dammit, you're right. We'll have to get it ourselves," Starlight sighed. "Come on." The two Night Furies slipped into Berk to get their own fish. They didn't want to see their riders or the other dragons. It wouldn't end well.

After sneaking a sizeable amount of fish from the docks, they sneaked over to the Great Hall, where they found Hiccup, Astrid and Brenna reading a few papers. They tried to sneak out of the forge, but they were caught. Starlight knocked over an axe and that collapsed onto a shield. There was a loud bang as the two made contact. The three teens jumped and looked at the two guilty Night Furies.

"Oh, hello, you two," Hiccup smiled, gracing the dragons with a smile before going back to the papers. This was annoying them already.

*Norse "What are you reading?" Starlight asked.

"Just something about the giant grey spider. It's actually really interesting," Brenna replied. "And what a coincidence! They're about the same size as you! Possibly even bigger! It's incredible!"

*Norse "You don't seriously believe them?" Starlight asked. *Norse "There's no proof that they're real!"

"There's no proof that they aren't," Astrid pointed out. Toothless and Starlight looked at each other, then to the three dragon riders . . . and laughed their scales off.

*Norse "This is ridiculous!" Starlight mocked. *Norse "You're getting worked up over nothing!"

"Have fun searching for something that isn't real!" Toothless taunted, as they left the Great Hall laughing hysterically to each other. "Giant grey spiders! I think our humans are crazy."

"I don't think our humans are crazy; I know our humans are crazy!" Starlight had to one-up Toothless with the insults concerning their humans. If they became good friends first, then they could progress to being a couple later. At least, that was how she saw it.

"I wonder what the other dragons would say when we tell them about the dumb things our human just told us," Toothless wondered. "They probably wouldn't believe it." As they walked, they bumped into Hookfang, who suddenly seemed eager to talk to them.

"Have you heard?" he asked.

"Heard what?" Toothless and Starlight chorused.

"About the giant grey spider, of course. I can't believe you haven't heard about it by now," Hookfang gossiped.

"I thought those weren't real," Toothless muttered.

"Oh, they're real, all right. Ask anyone," Hookfang smiled, as he flew away. Confused, the two Night Furies went and asked around, and got the same answers.

"Of course they're real!"

"I heard they're venomous, with fangs as big as my claws! No, bigger than that!"

"Aren't they around your size? It would be pretty cool to see you standing next to one of these spiders." Toothless and Starlight were beginning to get rather scared. Neither wanted to deal with giant spiders. They hated dealing with normal, tiny spiders. Neither Toothless nor Starlight could comprehend the possibility of spiders as big as themselves. Nevertheless, the two Night Furies were seriously spooked.

"This is crazy," Starlight blurted out. She talked a lot when she was nervous. "Giant grey spiders? It's absolutely ridiculous that-" A rustle was heard from the bushes. The Night Furies jumped. "What was that? Hello? Who is it? Come out and face us!" There was no reply.

"Let's just keep walking," Toothless soothed. "I'm sure there's some fish in the arena." They two continued on their journey, when they heard scratching against a wooden surface. "Holy Thor!"

"What's going on?" Starlight whimpered. "Maybe there are giant grey spiders?"

"That can't be right," Toothless scoffed, nuzzling Starlight's neck to reassure her. But as they turned a corner, they found the biggest web they had ever seen. And a big web could only be made by a big spider. The two Night Furies gulped fearfully. "Maybe we should get going a little faster."

"I think you're right," Starlight hurriedly agreed, as they started running. They got to the arena all out of breath, their stomachs pleading for food. But once Toothless and Starlight got settled, they heard the rustling sounds that had followed them everywhere. It was driving them insane. Both got up to see what was making such an annoying noise. Light seemed to be shining on it, allowing a shadow of a wiry but strong-looking leg to be seen. The two went to get a closer look . . . and saw two giant grey spiders. The stories were horribly, horribly real.

"GIANT GREY SPIDER! RUN!" Toothless and Starlight screamed, as they raced back to the arena, where they could expect to find fish and warmth. They didn't expect to find two large buckets of paint attached to a wire that Hiccup and Brenna yanked on to bring it cascading down on their heads. A sea of red, blues, greens, yellows, whites and pinks fell onto the terrified Night Fury's heads. After witnessing all that, neither of the two dragon riders could hold in their laughter any longer, and they collapsed with mirth.

"And that's revenge for yesterday!" Brenna laughed.

"What?" they chorused, utterly shocked. The nerds laughed hysterically. That was when the memories of all their pranks hit them like a ton of bricks. Starlight was on the defence almost immediately.

"Hey, we may have messed with you a little, but there was no reason for you to use paint on us!" Starlight snapped. The nerds faltered, their celebrations quieting.

"Did you take us and our feelings into account at all?" Toothless snapped. Hiccup and Brenna stopped celebrating altogether and started looking rather guilty. The Night Furies had their respective humans by their emotions, and there was nothing either of them could do about it. All they had to do now was wait for their humans overactive and flawed sense of logic to decide their next actions.

"Wow. When you put it all into perspective like that, we really did go too far," Brenna murmured, hanging her head.

"We should make it up to them by getting all that paint off them," Hiccup decided. Toothless and Starlight flashed smug grins at each other. They were the undisputed masters of manipulation.

"The cove should be the perfect place to clean them off. Lots of space and privacy for them," Brenna gushed. "How about you wait there for us?"

"These humans are dumber than what we give them credit for," Starlight whispered to Toothless, as they left.

"This is nothing. You should see the things they get up to when they try to find the answer to something," Toothless whispered back, as he led Starlight to a shortcut. Hiccup and Brenna looked at each other and high-fived each other.

"It's working perfectly," Brenna whispered.

"I can't wait for the next part," Hiccup grinned.

"BAHAHAHAHAHAHAHAHAHAHA! NOHOHOHOHOHOHOHOHOHOHO MOHOHOHOHOHOHOHOHOHOHOHORE!" Toothless laughed, as paint was scrubbed off his wings. Why on earth would the gods feel the need to give him such insanely ticklish wings?

*Norse "WE'LL NEHEHEHEHEHEVER PRANK YOU AGAHAHAHAHAHAHAIN!" Starlight promised, while Brenna washed the paint off her stomach.

"Really? You won't?" Brenna asked, teasingly. "Nothing? Nothing at all from either of you?"

"NOHOHOHOHOHOHOHOTHING EHEHEHEHEHEHEHEHEHEVER AGAHAHAHAHAHAHAHAIN!" they swore. Brenna translated for Hiccup, and the two geeks came to a compromise.

"Well, we have good news and bad news. The good news is we agree and promise not to prank you if you don't prank us," Hiccup announced.

*Norse "WHAHAHAHAHAHAHAHAHAT'S THE BAHAHAHAHAHAHAHAHAD NEHEHEHEHEHEHEHEWS?" Starlight asked.

"The bad news is you're still covered in paint, and it's going to take a while to come off," Brenna replied, scrubbing at Starlight's scales much harder. The last two Night Furies screamed with laughter as tears of mirth flowed out of their eyes like miniature rivers.

"NOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHOHO!" Toothless and Starlight howled.

After the paint had finally been cleaned off, Toothless and Starlight opted not to sleep in the house with their riders, who would likely take advantage of how sensitive they had (temporarily) become and torture them all night, like they had done before. On their way to a reliable abandoned barn, they bumped into Hookfang, Stormfly, Barf, Belch and Meatlug. "Oh, hey, you guys," Toothless and Starlight greeted awkwardly. Hookfang grinned.

"Guess what a little birdy told us about you two," Hookfang snickered. He, Barf and Belch trapped Toothless, while Stormfly and Meatlug stood close to Starlight.

"What did the little birdy say?" Toothless asked.

"Oh, I'm sure you'll find out," Stormfly grinned as they pounced. Toothless and Starlight were in for a very long night.
