Based on a post I made a looooong time ago, and I only just finished writing this. I hope you guys enjoy it!

"Do you think Emma would want a whale shark?"

"That depends, are we talking about a toy or the real thing?" said Jack, smirking, "'cause I doubt North can get a giant shark to fit in the house."

"Very funny," Hiccup replied, hefting up the front end of the giant plush to find the tag, "Blue or gray?"

"You have to ask?"

"Of course, why did I even bother?" Hiccup chuckled, but quickly blanched when he looked at the price, "…but would she really like a whale shark…maybe she'd like a penguin better?"

"I dunno, that feels a little cliché, don't you think?"

"True…but they were pretty cute," the brunet picked up the tag of a plush penguin, then quickly let it drop, "The price not so much."

"How much was it?" Before Hiccup could answer, Jack had already looked. His eyes widened and the two gave a look at each other before swiftly turning around, "I think I hear my wallet crying."

"Same here," Hiccup gently patted his pocket, "Maybe we can get her a phone charm instead, those seem more in our price range."

"There's an idea," Jack sighed, "The actual penguins were way cuter."

"Yeah, and the stingray pools nearby were really fun."

"Until some kids got upset that you were attracting all the rays."

"I was not!"

"Yeah you were, or did you not notice all of them splashing and swimming on top of each other to get at you," he explained, "They were practically stacking on top of each other like pancakes!"

Hiccup nervously busied himself with the picture books on the shelf, "…Were they really?"

"Oh yeah," Jack leaned on the shorter male, remembering the bright goofy chuckles coming from the freckled teen, "It was adorable, and then we went to the deep sea exhibits, and you got even cuter."

"I was not cute!"

"Oh come on, you were gushing about their 'bio-luminescence' and stuff like that."

"They can provide their own light source!" Hiccup waved his hands frantically, "How could anyone not be excited!? Do you know how cool that is!? I mean, they have specialized organs that-"

Jack listened with a grin on his face while half-heartedly looking through the various colorful t-shirts, with absolutely no intention of buying any of them, "See, very cute."

Hiccup froze, blushed, and stuffed his hands in his worn-out jacket, "I am not."

"Okay, okay, fine, you can call me out on squealing like a little girl when we saw the otters, how 'bout that?"

"Your eyes were literally sparkling."

"So were yours."

"Shush you, it's my turn to poke fun."

"Yes sir," he mock-saluted.

"To be fair, those two otters sleeping on the pile of ice were pretty cute."

"Right!?" Jack pulled an otter plush off the shelf, "Look at this face and tell me you wouldn't wanna cuddle with it!"

"The otter, sure. You?" Hiccup shrugged, "Eh."

"Harsh, Hic," Jack pouted, "And here I was, planning on cuddling the daylights out of you tonight."

"Thank gods I got out of that one."

"Mean," Jack poked Hiccup's side, grinning mischievously when the brunet squeaked.

"You stop that," he protectively covered the affected spot, "if you wanna poke something, go back to the tide pools."

"But the sea anemones don't make sounds when I poke them!" he complained.

"You mean like the sound you made when you poked the wrong end of a sea urchin?"

"That was a cry of pain, how dare you."

"The kids all had a nice laugh."

"They're lucky they're cute," Jack grumbled. Hiccup chuckled.

"At least the shark pools weren't so bad."

"Until the same thing with the rays happened with them."

"They were not fighting for my attention!"

"Then explain why all those sharks were swimming your way!"

"M-maybe I smelled like dead fish, I don't know!" he spluttered, waving his arms hopelessly, "Where are those phone charms!? There they are!" he quickly made his way to the other side of the store, trying to ignore the heat collecting in his cheeks.

Jack caught him before he got too far and wrapped an arm around the flustered boy's waist, "Trust me Hic, you aren't even close to smelling like fish," he let his cheek rest on top of Hiccup's head, "You smell clean, like soap."

The brunet pouted, still staring in the direction of the charms. His eyes lit up when he caught sight of something off to the side. He tugged at Jack's hoodie, "Jack look!"

"Hm?"

"Over here!" He pulled him over to another shelf holding large plush…horseshoe crabs?

"Wow, I didn't know they sold these," Jack picked one up to examine, "They look like facehuggers, Hic."

"They are not facehuggers," He took the plush out of Jack's hands, "They're living fossils! And you remember what the lady said, their blue blood saved her life!"

"Yeah, it's cool, but it still doesn't help with the 'alien' factor."

"But isn't that amazing!?"

Jack took back the plush, "If we buy this, Emma's gonna think we bought her a facehugger."

"It's not a facehugger, horseshoe crabs are completely harmless," Hiccup took it back with a huff, but gave the underside a long look. As much as he hated to admit it, it did look quite beastly, "For the most part…okay fine, let's go find those charms just in case."

The two circled the nearby rack and shuffled through the tiny sea animals ranging from otters to jellyfish.

"Do you think she'd like a turtle?" asked Hiccup, poking a plush sea turtle.

Jack hummed, "She might, but again, kinda cliché," he picked up the whale shark, "This one's kinda cute," he gave it a gentle squeeze between his fingers.

"But does she like whale sharks?"

"Good question, I don't think Emma and I have ever talked about sea animals," he rubbed his chin, "Actually, let's look for a whale, she might like that, or a shark."

"So a whale or a shark, but not a whale shark?"

Jack threw him a wink and went back to looking through rows upon rows of charms.

Hiccup chuckled and shook his head, ready to go back to rummaging through various plush animals, but his attention was soon caught by one of the charms hanging innocently on a hook.

A stingray.

It was small and gray, and there was another one behind it, but in blue and looked more like a manta ray. Hiccup picked up the gray one and let it rest in his palm, it was soft and plain, and there wasn't much of a face, just two black spots for the eyes. It was actually very adorable.

But. Hiccup already had his fun today, Jack taking him to the aquarium was already a special treat. Now, they were here to get something for Emma. He shook his head and was about to put it back until a pale hand swiped it out of his palm.

His head shot up, seeing Jack already walking towards the cashier. Hiccup quickly ran over and caught him by the sleeve.

"Jack! What are you doing?"

"You like it, right? So let's get it."

Hiccup tried grabbing it, but Jack had moved his hand away, "But I don't need it."

"But you like it, right?" Jack moved out of the way, expertly avoiding the thin hands reaching for the charm. At this point, Hiccup was chasing the older boy around the shop, trying his hardest to get the charm and put it back.

"I don't need it, Jack, it's fine," he pressed. Jack suddenly stopped, letting the freckled boy bump into him, the charm still out of arms reach.

"But you like it, right?"

Hiccup sighed, pouting, "You're not gonna stop until I give in, are you?"

"Nope."

He bit his lip, and sighed again, "Fine."

Jack grinned widely, "Alright then, let's get the other one so we can match!"

"Wh-what?" he spluttered, "But-!"

"C'mon, it can be another one of those coupley-things Astrid can make fun of us for!"

"What about Emma?"

Jack winked, "I got it covered."

Later that evening, the boys surprised Emma with a very adorable horseshoe crab doll.
