"Dad!" Hiccup tumbled off of his bed and into the main room of the hut. "Dad, have you seen my socks?"

Stoick sighed. "Hiccup, for the last time, it's not my job to keep track of your socks. I've got enough to do."

"I can't find them anywhere. I've had a few go missing, but now they're all gone."

"Check with the dragon."

Hiccup looked suspiciously at Toothless. "You haven't been into my socks, have you?"

Toothless shook his head, looking highly offended.

"What would a dragon do with socks, anyways?" Hiccup shrugged. "I guess I'll go without. Now where's… oh no."

"Hiccup, if you say that you can't find your boot…"

"I can't. Honestly, I put it right here."

"You need to keep better track of your things."

"No, really. This is exactly where I left it. It's gone."

"Well, if you can't keep track of your one boot…"

"Dad!" Hiccup sighed. "I need to meet up with the other dragon riders, boot or no boot. I'll see you later. Come on, Toothless."

Snotlout bumped into him as he was going out the door. "Hey, Hiccup. What's the matter? Lose your boot?"

"As a matter of fact, yes."

"You only have one boot, and you still managed to lose it?"

Hiccup glared at him. "You only have one head. I see you've lost that as well."

"Hiccup!" Gobber came running towards them, equally barefoot. "It's happened! The trolls!"

"What?"

"The new breed of trolls! They take only the right socks! And they steal boots as well!"

Hiccup facepalmed. "Oh no. Not you too. Well, now I can tell my dad I'm not the only one."

"Hiccup." Stoick appeared behind him, also barefoot. "You haven't been into my…"

"It's the trolls, Stoick!" announced Gobber. "They're stealing right socks and boots now!"

"Or maybe you should keep better track of your stuff, Dad," muttered Hiccup.

"That's not funny."

"We need to outsmart them, the wily rascals," said Gobber. "Set a trap."

"Gobber, I doubt it's the trolls."

"Well, how do you know it isn't?"

"You know… you may be onto something. Look, I'll figure this out. Right now I need to get down to the academy."

"Hiccup, is there a reason you have no shoes… err, shoe?" asked Fishlegs.

"Oh for the love of… if I have to answer this one more time…"

"Well?" inquired Astrid.

"Trolls."

"Trolls?"

"Well, that's Gobber's theory."

"You think that the trolls stole your shoe."

"I said that it was Gobber's theory!" protested Hiccup. "I'm not quite sure what to think. I mean, it seems like such a mystery that only certain people's right socks and shoes would be vanishing suddenly."

"I know, right?" said Tuffnut. "Totally weird."

"Completely," added Ruffnut.

"Let's get started on some training, then I'm going to go buy some new right socks and put them in my drawer where they belong."

While the other riders worked on training exercises, Hiccup motioned Astrid aside.

"So, trolls, huh?" said Astrid.

"Yeah, Gobber's convinced it's a new species." Hiccup sighed and shook his head. "I have a hunch about who our trolls might be, but I need some help."

"With what?"

"Troll trap."

Stoick was awakened late that night by a loud clatter from Hiccup's room. "What in the world… HICCUP?"

"Good news, Dad!" Hiccup appeared in the doorway, disheveled and grinning. "We caught the trolls."

"Oh, you did, did you?"

Astrid stood in the room triumphantly, her arms crossed. Dangling from a rope in the middle of the ceiling were the twins.

Stoick shook his head. "I might've known. Gobber will be happy that his trolls have been caught."

The twins grinned broadly, performing an upside-down fistbump. "LOKI'D!"
