How to train your Dragon Chapter 1: Welcome to Berk

The opening scene stays the same, except there are a couple more dragon species. I'll list them off when Hiccup is talking about the dragons and what sort of reward he would get for killing them.

Random viking:"Fire! Someone put it out!"

A group of teens is shown running by, grabbing buckets and water from a cart a broad shouldered, black haired boy wheeled in.

Hiccup VO: That's the other kids. Fishlegs, Dogsbreath, the twins Ruffnut and Tuffnut, my cousins Snotlout and Ulfhild, and (in a dreamy voice) Astrid. They have a much cooler job than me.

Gobber walks by:"Back to work. This ain't no time to slack."

Hiccup:"Just let me out there. I want to leave a mark."

Gobber:"You left plenty o'marks, boy. Just not good ones. Now sharpen the swords."

Hiccup:"But why? I can go out there, I can help, if you would just..."

Gobber:"Ye can't lift a hammer, ye can't swing an axe, ye can't hold a spear or sword properly and ye can't even throw one of these!" Holds up bolas, which a viking snatches and throws at a nearby nadder on the ground, tying it up, causing it to trip and fall over.

Hiccup: walks over to the contraption that I don't know the name of "This will throw them for me" he says, accidentally pulling the trigger and knocking out silent Sven who just walked by for a new axe "It still needs some adjustments."

Gobber: facepalms "Look, kid. Just stay here. Ye ain't ready for it out there. Now 'scuse me, they need me out there. Stay! Here!" He runs out, switching his hook for a mallet and grabbing an axe.

Hiccup VO: Killing dragons, in our village, is everything. I will get out there, one day, and earn my name. A Nadder head is sure to get me noticed (a nadder is seen hopping around on a roof, breathing fire down from it). A terror is not much, but taking down a flock of them is a one way ticket to great respect (A group of at least twenty terrors are flying around a group of vikings, biting and retreating to fire a ball of fire). Gronckles are tough. Taking down one of those will definitely get me a girlfiend (a pair of gronckles is seen picking up a rack of fish each, stealing them). No kill shows off ones instinct and awareness more than a changewing. They camouflage themselves, and spit lethal acid (a changewing shows up behind the teens, knocking over Fishlegs, before Astrid and Snotlout jump on the horns on the side of its head, distracting it before Spitelout jumps in and slams both fists into it, sending it scurrying away). Zipplebacks are tricky. Two heads, double the respect. These dragons are highly destructive with their gas and spark attack (a zippleback is shown busting through the roof of a house and filling it with gas, before the other head smashes in the door and blasts it). Only the greatest archers and spear throwers can brag about defeating a timberjack. These massive dragons are difficult to take down because they never land, but besides their sharp wings (a timberjack is shown cutting down one of the tall fire pillars) they arent that destructive besides the collateral damage (the fire pillar crushes a nearby house, while setting fire to another one). Though that's only because they don't have the same tendencies as the other ones.

Stoick: "They found the sheep! Spitelout, Phlegma, take some fighters and go there! Ack, Ivar, with me to the catapults!

Spitelout: "Right away, chief! Move it!"

Hiccup VO: And then there's the monstrous nightmare. Only the toughest and bravest vikings dare take those on. They have a bad temper, a hot fire, and a nasty habit of lighting themselves on fire. (The nightmare is clibing up the catapults, going face to face with Stoick)

Stoick:"Keep firing. I'll deal with this" he proceeds to beat the shit out of it with a hammer, before sending it away.

Hiccup VO: And then there is one dragon, that noone has ever seen. It never shows, never steals any food and never misses. We call it...
