Well, we left off with dragon eggs about to hatch on Berk.

Let the chaos ensue.

...

The teens met up in the town square, all of them grinning from their successful deliveries of Gronckle and Scauldron eggs. Astrid beamed the widest. "Wasn't this a great idea?".

Fishlegs squirmed excitedly. "Uh-huh! Everyone's going to be so surprised!".

A sudden explosion blasted off the door of a house as a small, scaly ball shot out, slammed into Helen's stomach, and rebounded into the air.

Sasslout cackled with malicious glee. "Surprise!".

The same thing that had hit Helen came back down on Sasslout's helmet. "Hffff.". She crashed to the ground, completely unconscious.

The baby Gronckle sat up, yawned, and regarded the teens with sleepy eyes. The Thorstons and Snotlout all bent over, cooing.

Astrid, however, let out a gasp of horror. "The eggs explode?".

Another house blew up in a burst of flame, while a second fell victim of a blast of superheated liquid.

"The eggs explode!".

More blasts of flame and boiling water began erupting from the houses that had received dragon eggs, vikings punching through their doors and walls, screaming as they tried to escape their burning dwellings. Astrid moaned. "I'm sorry! I'm sorry!".

A flaming Gronckle bounced off a midair Scauldron and hit the Snoggletog Tree. The wooden structure began to burn, more missiles scorching the sides. The Thorstons all grinned like maniacs.

"Awesome!".

"Wow!".

"Magnificent!".

"This was your best idea yet!".

Astrid flinched at that last one, and only got worse when Stoick thundered into the plaza and noticed the merry green torch where the tree used to be. "What in Thor's name is goin' on?!".

Astrid whimpered out, "The eggs explode.".

On cue, the last egg hatched and another house crashed to the ground as a burning pile of timber.

Jalf grinned. "I need about sixty dozen more of those eggs!".

...

Meanwhile, Hiccup and Himinn had been exploring the island a bit more and had found the rest of the Rider's dragons.

Hiccup grinned. "Hookfang!". The Nightmare growled and nodded.

Himinn laughed. "Hi, Whirlwind, Flage. You guys have kids?".

The Typhoomerang roared and Camo flapped down with a group of babies on his back, apparently taking them for a joyride. A male Typhoomerang flew over with a pile of fish.

"Ahh, the whole family's here!".

Hiccup laughed as Stormfly's three hatchlings nuzzled his arm, squeaking. "Who knew you guys came here to celebrate your own sort of holiday?".

His face fell when he realized he'd left his family back on Berk. "I guess we should get back to our holiday. Himinn?".

She whistled sharply and Bolt flapped up, Endeavour following him. Both Haddocks mounted and the dragons spread their wings and soared into the wind. "We'll see you back on Berk when you're good and ready?".

Their plans were rendered null and void when Stormfly squawked and took flight, followed by Doomdrill, Meatlug, and then the rest of the dragons, all rising into one tremendous flock. Hiccup gasped. "Oh, no, nonononono!".

"Too late, bro! I think we started the return migration!".

Even the babies let out tiny chirps and ran for the edge of a cliff, a couple of Nadders calling encouragement.

Hiccup shrugged. "Well, if they insist!".

The first few babies, two Nadders and an Exterminator, sprang off and flapped their tiny wings, clumsily climbing towards their parents... and the wind caught them and swept them back to the island like little scaly pinballs.

"This is never gonna work.".

Hiccup sighed as the babies called to their parents, running a hand over Endeavour's back absentmindedly, then straightened up with an epiphany. "Oh! I've got just the thing!".

Himinn looked over. "What?".

"There was an old ship on one of the rocks! I bet we can use it to carry the babies!".

She nodded and patted Bolt's neck. He roared and a group of Nightmares flew over with Stormfly and a few Gronckles. "We'll need some heavy lifters!".

...

Back on Berk, Fishlegs and Helen had been made responsible for looking after the babies while the rest of the vikings set about fixing the village and a supervising Stoick lamented to Gobber. "This is a disaster.".

Gobber shook his head. "It's not that bad.".

"Oh, not that bad? The village is destroyed, the dragons have up and left us, and-". His rant came to a pause as they encountered a crowd of people looking into the sky with expressions of awe. "What are these people looking at?".

He followed their sightline, gazed into the clouds. "What is that?".

That was the old ship, dragons clinging to it with ropes.

Wait, dragons?

Sure enough, there they were. A multicolored supersized flock of dragons, descending towards the village, Endeavour and Bolt leading them.

Stoick gasped and his face broke into a smile. "It's Hiccup and Himinn!".

Astrid, hammering a board back onto a building, grinned. "And our dragons!".

The village burst into cheer. The dragons made their approach, the ship landing firmly on the ground and sliding along, leaving a line in the snow, stopping in front of the chief.

The dragons dropped the ropes.

The villagers stared for a moment, and a curious baby Nadder poked its head over the side, cheeping.

The adult dragons landed and the babies sprang out of the ship, making a beeline for their parents.

Snotlout was the first to run forwards as the village shouted happily, pulling Hookfang's head into a hug. Sasslout followed, dashing towards Whirlwind who roared happily.

...

Meatlug and Spout forlornly gazed over the village, looking for their babies, and gazing towards Helen and Fishlegs' calls.

Each held up a baby dragon.

Overjoyed, the mother dragons landed and wasted no time in barfing up fish for their congregating offspring as the baby dragons moved towards what they instinctively knew was their family. The reunion halted when Fishlegs called out, "MEATLUG!", and slammed into his dragon with a hug, sending her rolling through an undamaged wall.

...

Astrid dropped her tough warriorness and dashed over to Stormfly. "Stormfly! You're back! Ohhh, and with babies!".

Stormfly leaned down. "Kids, this is your Aunt Astrid. Treat her with respect.".

The babies ran up, all hoping for attention as Astrid crouched down to pet them.

...

Endeavour roared at the top of his draconic lungs and Jalf, squealing, slammed into his dragon's side. "I missed you so much! Where's the babies?!".

Cinder chuckled and walked over, herding the babies towards him. Jalf squealed again and scooped them up into hugs. "Finally, I have my air force of mass destruction!".

Himinn sniffed as she walked up, tears in her eyes. "He's already got a destructive power he's going to abuse!".

Jardar sighed. "The apple doesn't fall far from the tree.".

"Turn around.".

He obeyed and gasped in delight when Doomdrill held up her tail, revealing the baby Whispering Deaths curled around it. "Doomdrill!". He looked at the babies. "Oh, they're...".

Himinn smiled. "Lost for words?".

"...yes.".

She pulled him closer. "I missed you while I was gone. C'mere.".

Jalf looked towards them until Gobber ran over and covered his eyes. "Hey! Gobber! I wanna see!".

"Don't worry, you'll see enough of that once you have a girlfriend.".

...

Hiccup watched the reunions with a smile until Stoick pulled him into a hug. "Well done, son!".

"Thanks... dad... need... air!".

"Right, sorry.". The chief placed his heir back on the ground and threw his arms in then air. "EVERYONE! GRAB YER DRAGONS! TO THE GREAT HALL! We finally have something to celebrate!".

...

Alright, I'll post the Great Hall bit along with the end of the film in a few days. Maybe longer, but it will be posted. That's all for now though, so stay tuned for the conclusion!
