Its Love Frostcup/hijack

Jack Frost,a frosty boy with white hair and pale skin,was flying through the wind.It was weird,water was In the wind.He turned around and cocked his head.He stood on a tower and leaned,only hanging on by his hand. "Wind,take me to the ocean!" He yelled,he was gonna check up on what's going on.He saw huge waves,and sat by the dock,his feet dangling over the water.He smiled and lied down,but something yanked at it.He screamed and jump back.  

"What....the hell?" Jack then spotted a shark fin,looking like its waiting at the dock.Jack got up and ran,and kept staring back at him.He ran into a brown haired boy with freckles,not wearing much.

"Uh,Uh sorry.." The boy said,scratching the back of his head.

"I'm Jack," He smiled,studying the boys face.

"Uh,nice to meet you Jack.Now if you excuse me....I got to go," He said,trying to leave.   "I don't even know your name!" Jack exclaimed,grabbing his arm.

"Its Hiccup," He sighed.

"Look behind you,Woah!" Hiccup yelled,as Jack turned around.He saw nothing.He looked back and Hiccup was gone.

"I'll find you again," Jack mumbled.

He had to.

He flew to North. "North,do you have anything on Hiccup Haddock?"

"Yes,he's on the nice list.He-"

"No,stuff about him.He's fast and quick,and disappeared by the dock,"

"People call him shark tale.He spends so much time at the water no one ever sees him.No one knows his family members,nothing.Why are you so interested in this boy?"

"There's just something about him.What time does he usually go to the dock?"

"4:00 o'clock.Exactly.People say when he's by the dock sharks always come."

"Ok,at 4:00 o'clock tomorrow I'm going to find out things."

"How?" North arched an eyebrow.

"My way," Jack smirked widely and swung his staff over his shoulder.

The next day,everyone was swimming at the beach.It was exactly 3:59 O'clock.Jack hid under the dock,as he heard footsteps.He saw the boys feet and smiled.It was Hiccup.He snuck up behind him as Hiccup looked side to side.He was about to jump in,as the sharks started to appear.Jack caught him as his foot touched the water,and Hiccup squirmed in fear. "LET ME GO!" He yelled trying to shake the the water off his foot.Jack wouldn't let go,but the shark came close and tried to nip at jack.It tried jumped and eating him.Jack carried Hiccup bridal style and brought him on top of the dock. "Why won't you let me go?!" Jack pinned him down. "I want to know what's going on,Hiccup.I can stay here ALL day." Jack spat,a stern look on his face.  

"Just get away!" Hiccup yelled and ran from Jacks grip,running to the edge of the dock. "HICCUP WAIT.THERES A SHARK!" Jack yelled reaching out for him,grabbing his foot  as Hiccup's other half was in. "OH NO!" Hiccup yelled his his foot turned into a fin,and it was slippery.He slipped our of Jacks grip and the shark followed him.

Hiccups POV

I got away luckily.Toothless looked at me worriedly.I pet him. "its ok bud.We wasn't hurting me.Just thought you would hurt me," I  hopped on my shark and he brought me to the tribe.  "Hiccup,you made it here safely," My dad smiled,patting me on the back.

"Not safely," Snotlout spat.

"A boy was pinning him down.Grabbing him,"

"What!?You could've gave us away,son.Stay far away from that boy.He may tell everyone."

"No problem," I sighed,swimming over to Astrid,Fishlegs,Ruffnut and Tuffnut with Snotlout  following me.

"Wait...there's a human here!" Fishlegs yelled.My dad widened his eyes and got a sword. "Sharks...get ready to attack!" I widened my eyes.It might be the guy with white hair.Jack...I think.I snuck away and saw him setting down his jacket at the dock,and turned around.

"Hiccup!Are you okay?" He asked,staring at me. "Yea,you have to go!"

"But why?"

"Just go!"

I heard my dad in the distance.

"THERE HE IS!"
