In a village with wooden huts. Vikings walking along the paths doing their everyday things. Dragons of countless species fly in the blue sky.
Turtles: woooaaahhh
Hiccup: I know it's pretty great, ain't it?
Toothless sniffs Leo
Leo: hey there-e
Nina and Kiara were unconscious on Toothless's back.
Mikey: um.... Hiccup, do you, well happen to have any.... Errr.... Pizza?
Hiccup: what's pizza?
Mikey's head explodes
Mikey: YOU DONT KNOW WHAT PIZZA IS?!
Hiccup: nope, well I have a few friends I'll like you guys to meet.
Hiccup walks down a windy path way leading to a arena.
Raph: cool! So you guys have battles in this arena?
Hiccup: sort-off, we kinda stopped now
Raph: LAME
Dani: this is just like the movie!
Day: why did Nina and Kiara pass out?
Ashley: they are HUGE fans of this tv show
Rozy: yeah, HUGE fans of turtles too
Day: so they are fangirls?
Ashley: we are technically fangirls too, because look where we are!
Day: suppose so
Three guys and two girls waited for Hiccup in the arena. Four dragons stood in wait behind them. The turtles, the girls, Toothless and Hiccup entered the arena.
Snotlout: man Hiccup you take fore- Snotlout stopped talking when he saw the turtles
Astrid, Ruffnut, Tuffnut, Fishlegs and Snotlout's faces:

Snotlout (whispers loudly): there are giant green things behind you! Walk slowly towards me...
Hiccup (laughs nervously): well you see, I found these guys in the forest, they're not from here. And they are friendly and I'm pretty sure they won't attack us....
Astrid: and YOU BRING THEM TO THE VILLAGE?!
Hiccup: that's correct
Mikey's jaw dropped. His heart raced and his eyes turned dreamy. The blonde girl in front of him has drop dead gorgeous. She seemed pretty feisty too. Nice.
Mikey (saying smoothly): hey there, my name is Micheangelo, but you can call me Mikey, what may yours be?
Astrid (rolled her eyes): my names Astrid, and I'm not interested.
Mikey pouted
Hiccup smirked.
Fishlegs: are you sure they won't attack us? They have weapons on their shells.
Leo: oh, don't worry, we won't attack you. We are as civilized as you.
Snoutlout (to himself): yeah, what next? Talking broomsticks?
Raph: I heard that!
Snotlout: good
Hiccup: ok let's start by knowing all of your names
Leo: I am Leonardo, or Leo for short
Donnie: Donnatello, Donnie for short
Raph: My name is Raphael, Raph for short
Mikey: you already know me
Day: I'm Day
Ashley: I'm Ashley
Rozy: Imma Rozy and I like dragons
Dani: I'm Dani
Tuffnut: what about those people? Are they dead? He points at Nina and Kiara
Ruffnut: if they are dead, can we have them?
Dani: they're not dead they're unconscious.
Tuffnut: aaaawwwww
Ashley (extremely excited): OK, PLEEEAAASSEE CAN YOU TEACH US HOW TO TRAIN DRAGONS?!
Raph: No way!
Astrid: I'm with greeny! There's no way we are gonna teach you guys all of Berks secrets!
Raph: don't call me greeny!
Astrid: whatever
Nina and Kiara wake up. Their faces are plastered with pure delight.
Nina and Kiara: WE'RE IN THE HOW TO TRAIN YOUR DRAGON MOVIE!
Nina: AND WE'RE SITTING ON THE TOOTHLESS!
They both squealed and passed out again.
Hiccup: I'm gonna pretend that I didn't see that.
Leo: same here
Donnie: Hiccup? Is it okay if I study these dragons a bit closer? I mean, like, their really magnificent creatures, and deserve to be written in all books!
Fishlegs: oh, there's no need. I have already made a whole book about them. It's called 'the book of dragons'!
Raph: okay I prefer riding a dragon than to listening to these two nerds.
Mikey: agreed
Hiccup: okay, since the elves and goblin are the least familiar to this, we're gonna split them up. So you guys can choose which dragon out of these ones (he points at Toothless, Hookfang, Barf and Belch, Meatlug and Stormfly)
Leo runs to Toothless and mounts him.
Raph runs up to Hookfang.
Donnie goes onto Barf and Belch.
And Mikey goes onto Stormfly.
Mikey: I guess I'll be riding with you, Astrid...
Astrid slaps Mikey in the face and gets onto Stormfly.
Hiccup joins Leo on Toothless, Snotlout joins Raph on Hookfang and Ruffnut and Tuffnut joins Donnie on Barf and Belch.
Just to simplify on what you're picturing:

xxxxx2 hours laterxxxxx

Donnie falls off Barf and Belch for the fifth time. Donnie was falling, heading straight for the ocean.
Donnie: HHHEEEELLLPPP
Tuffnut: I think we dropped something?
Ruffnut: oh! We dropped Donnie!
Tuffnut: okay then, let's go fetch him, again
Tuffnut and Ruffnut followed Donnie and caught him at the last minute.
Donnie (hanging upside down): I'd much rather read the book of dragons, can you guys drop me off?
Ruffnut: what did he say?
Tuffnut: I think he said we must drop him!
Donnie: WAIT! THATS NOT WHAT I ME-
Barf and Belch dropped Donnie. Donnie fell, he was waving his arms around.
Donnie: NOOOTTT AAGGAAAIINNNN!
Donnie landed face first into the ground. He tried to pull his head out of the hole but he was stuck.
Donnie (muffled): great, my head is stuck in the ground, AGAIN

Leo was holding on tightly to Toothless's saddle. Hiccup sat behind him.
Hiccup: okay the first thing you need to know is how to sit. Back straight, firm grip onto the saddle. Got it?
Leo straightened up a bit.
Hiccup: good, now left, you pull that way, and right, you pull that way. But when you're turning, make sure that you lean onto the opposite side.
Leo pulled Toothless's saddle to the right. Toothless did a sharp right turn, Leo nearly fell off him, but thankfully he didn't.
Leo: I'm getting the hang off this!
Hiccup: cool okay, you take the lead now.
Leo: but how do we land?
Hiccup: why?
Leo: cause we're about to hit the ground.
Hiccup looked ahead and saw that they were heading too fast to the ground.
Hiccup: pull up gently
Leo didn't hear the last part and yanked hard for Toothless to pull up.
Toothless pulled up really fast, he was flying vertically up.
Leo and Hiccup started sliding off Toothless's saddle. Hiccup and Leo fell of Toothless, the black dragon started falling too. They hit the ocean. Leo and Hiccup pulled their heads out off the icy sea.
Leo (nervously): wanna try again?

Raph took hold of the reins and made Hookfang go super fast, Raph was good at riding Hookfang. Snotlout refused to ride with Raph, so the turtle dropped Snotlout into the ocean.
Raph: this is the life!

Mikey started getting the hang of riding Stormfly. They rode fast against the wind. Mikey went faster on purpose, because then Astrid would normally hold him tighter around the waist. Mikey smirked.
Astrid: not too bad!
Mikey turned to face her and gave her a warm smile.
Mikey: thanks!
Astrid: WATCH OUT!
Mikey turned around and saw that they were heading straight for Hookfang and Raph.
Raph ducked out of the way just on time.
Raph: WATCH WHERE YOURE GOING!
Mikey: SORRY!
Astrid laughed.
Mikey gleamed.
Mikey made Stormfly go faster, and Astrid held Mikey around the waist. Mikey giggled.
xxxxx5 hours laterxxxxx

Leo tries to pull up. The the ocean only meters away.
Leo: c'mon Toothless! Pull up!
They kept going down, heading straight for the ocean.
Leo: PULL UPPPPPP!
Leo was freaking out. He shield his eyes as they were about to hit the water.
Toothless pulled up by himself.
Toothless: *cute laughing noise*
Leo: DONT LAUGH AT ME!
Toothless: *louder cute laughing noise*
Leo was now soaring in the sky. Raph pulled Hookfang so that he was flying alongside Leo.
Raph: BWAAHAHAHAHAHAHAHAHAHA!
Leo: shut it
Raph (says in between laughs): Toothless got you there, didn't he?
Leo: what ever
Mikey pulled Stormfly over to where his two older brothers were talking.
Mikey: let's have a race!
Leo: yeah! First one to the arena wins!
Raph: what about Donnie?
Mikey: oh, Donnie didn't want to ride the dragon anymore, so he's reading Fishleg's book about dragons.
Raph: oh well, in your marks, get set, GO
Raph flew straight ahead, Leo zoomed after him, Mikey lagged behind. Raph had a steady speed.
Raph: good Hookfang, now just keep going and we'll win. Then we can shove it in their poor loser faces.
Hookfang growled in pleasure and started going faster. They dodged small rocky islands jutting out of the ocean.
Leo could see Hookfang ahead. The only reason why Leo wasn't in front was because dodging the rocks took to much time.
Leo: Toothless, I have an idea. Pull up.
Leo tightened his grip on Toothless's saddle. He clicked Toothless's gear into a different setting. They pulled up with great speed. They were above the clouds, going full speed, with nothing in their way. Leo could see Raph and Hookfang beneath him. He smirked.
They over took Hookfang in the clouds. Leo held on tight and changed the gear. Toothless did barrel rolls till he reached the ocean. He pulled up before hitting the water. They were in front of Raph.
Raph: how did you?
Leo: can't catch me!
Leo flew faster, the arena was in view. Raph growled and flew faster. Toothless and Hookfang were flying side by side now, meters away from the arena. Leo reached out his hand. Raph stretched out his hand and pushed Leo back.
One meter away from the arena.
Mikey and Stormfly come out of nowhere and beat Raph and Leo at the last split second.
Mikey: BUYAKAASHAA!
Leo: 😦
Raph:😦
Hiccup: wow! You guys did so well!
Astrid: yeah, not too bad
Snotlout: I could have done better
Tuffnut: rrriiiiggghhhtttt
Ruffnut: do you even know what they are talking about?
Tuffnut: no
Day: you guys took the whole day to learn how to ride!
Leo: hehehe sorry
Ashley: WE DIDNT EVEN GET A TURN! AND NOW ITS ALREADY SUNSET!
Rozy: -_-
Rozy: you guys owe us
A pink portal appeared below the turtles and the girls, they got sucked in.
On forth to another ADVENTURE!

A/n: if I didn't use your dare I'm sorry. I will use it in next chapter! 😅😃
Tell me where they should go next!
