Full Description: "How to Start a Dragon Academy"

WARNING: This description contains heavy spoilers for the entire episode. 

The episode opens with Hiccup and the Viking Teens congregating on a pillar above the North Sea, and Hiccup suggests they have a "best tricks" competition. Snotlout arrogantly decides to go first but Hookfang has his own agenda. Instead the Nightmare takes Snotlout on a whirlwind ride, drawing him close to completely breaking down at every point. Luckily Snotlout makes it out alive...much to everyone else's annoyance.

Snotlout: "Can you do it without the dragon?"

Fishlegs and Meatlug go next, having a short routine of flying slowly in a circle before landing. After that is Ruffnut and Tuffnut on their Zippleback Barf and Belch. But the twin's inability to decide which way to fly ends up tangling the heads of the Zippleback and getting them thrown off their dragon. Luckily, they make it out alive as well (Ruffnut noting that they did, in fact, almost die).

Astrid goes next, telling Hiccup that he "might wanna take notes" on her new techniques, which she performs seamlessly, commanding Stormfly exact instructions and the dragon performs so beautifully. Still, though, when Hiccup and Toothless go Astrid is easily out-shined by the pair's completely in sync flying style and blinding speed. Astrid even remarks that Hiccup and Toothless are "still the best".

Meanwhile, back on Berk, the dragons are running wild around the village. Stealing food, breaking things, making themselves nice and cozy atop people's roofs. And of course there's the fact that they leave their 'droppings' all around the plaza, exactly at 3 o'clock every afternoon.

Terrible Terror stealing food

Hiccup, apologizes to local fishermen team Bucket and Mulch for the dragons, but they seem blissfully content with the chaos, simply telling Hiccup they have fish for Hiccup's father--or they did if a terrible terror hadn't eaten it.

Still, even though some people have adjusted to the dragons chaotic entrance into Berk, there's Mildew. A bitter man who lives behind the Great Hall and grows cabbages. He's immediately angered when a dragon is making noise on his roof and goes outside to see that the dragons have eaten his entire field of cabbages. Angered, Mildew goes into town.

The next day, Stoick and Gobber are overseeing the storage of food for the winter, and Mildew interrupts with his complaints about the dragons, getting the whole village stirred up in agreement with him that the dragons are a nuisance that need to be caged despite Hiccup trying to convince them that the dragons are "just dragons being dragons".

Stoick and Mildew at odds

Later that night Stoick, Gobber, and Hiccup are at home, discussing what is a plausible solution to the dragon issue and find nothing suitable until Hiccup suggests that he try and control the dragons himself. Stoick is reluctant to Hiccup's suggestions telling him he's "not a man yet" but gives Hiccup the chance to prove himself.

But the next day, Hiccup is put to the test while trying to control the dragons and fails miserably. Dragons go along chaotically, still stealing food, starting fights, and even setting sheep on fire!

That night, Hiccup is visited by Astrid who implies that the job is too big for one person to do, especially after Stoick chastised Hiccup on how his "master plan" isn't working. Hiccup then, realizing that his initial plan to control the dragons on his own isn't working he moves onto a new plan: have himself and the other Viking teens learn to train dragons themselves in the Kill Ring (though going behind his father's back to do so).

Hiccup and Astrid discuss his busy day

Despite the teen's good intentions on learning to control their dragons with tricks and techniques taught to them by Hiccup, they still fail to stop the dragons from eating the village's whole supply of food for the winter. Because of this tragedy Stoick finally gives into the complaints of Mildew and the village and issues Hiccup to cage all the dragons that night, and send them away the next morning.

The same night, at dinner, the teens sulk at that the fact that they'll have to cage and send their dragons off--fearing that they'll never see them again. Hiccup, though, refuses to accept this fate. Mildew approaches Hiccup saying that he was silly to think that dragons could be trained and that it's a dragon's nature to be reckless. But instead of his words discouraging Hiccup, it gives him an idea.

Caging the dragons

Later, the teens go off to the Kill Ring to say goodbye to their dragons--for they're to be caged that night--before Hiccup let's them free telling the teens that he has an idea to simply uses the dragons natural instincts to their benefit.

The next day the teens and their dragons go around the village and use their acquired knowledge to help catch more fish, herd the wild boar, and even plow and fertilize Mildew's cabbage field (though he's hardly thankful). Instead Mildew calls to Stoick's attention that the teen's dragons are caged.

"Berk Dragon Academy"

Later in the Kill Ring the teens think their getting in trouble but instead Gobber tells them that Stoick is giving them the arena to have their own Dragon Training Academy--much to Mildew's chagrin--and the rest of the dragons are released from their cages.

Stoick tells Hiccup to do what's best of the island with the academy and Hiccup promises to do with the help of Toothless and the others. Soon, a emblem of Toothless is put atop the Kill Ring's entrance as the new "Berk Dragon Academy"!
