After escaping Dagur, the riders head home and try to figure out what the Dragon Eye is. But after a rather dangerous try at opening it, Gothi realizes a keyhole-like indention looks a lot like a bite she received from a dragon when she was younger. The riders, with Gothi in tow, try to find the dragon that once attacked the old woman in hopes that a tooth will be the key to unlocking the secrets of the Dragon Eye.
Tropes:
- Artistic License – Physics: Being buried in snow would not be enough to cover a human's body heat. If anything, given how snow can be used as an insulator, it would make a person's body heat even more obvious.
- Back-Alley Doctor: Gobber, who sets a man's leg on fire with disinfectant, decides to cut a man's foot off when it has a thorn stuck in it, and when trying to cure a stomach flu, instead creates a hair growth formula.
- Bad Boss: Dagur makes two of his paltry crew jump overboard when Hiccup succeeds in stealing back the Dragon Eye.
- Beard of Sorrow: Inverted; Savage is clean-shaven.
- Bizarre Alien Senses: The Snow Wraith's eye sight is based off heat much like a Predator in hunting mode.
- Dark and Troubled Past: Gothi as a teenager and two others were attacked by a Snow Wraith, she was the only survivor. For a very good reason, she has no desire to go back to that peak.
- Every Scar Has a Story: Hiccup seeks to know Gothi's story about the bite marks on her arm to learn how to open the Dragon Eye.
- Gory Discretion Shot: The Snow Wraith drags Gothi's friends off-screen in the middle of a snow drift.
- Idiot Ball: Dagur not considering that Hiccup and Toothless would be swift and stealthy enough to rescue his friends and fly to do a Stealth Hi/Bye and steal the Dragon Eye.
- It's the Journey That Counts: Getting the tooth didn't really help Hiccup discover the secrets of the Dragon Eye, in fact it almost seems like the whole thing was a waste of time until Toothless making his bed activates the eye.
- Major Injury Underreaction: Tuff is rather unconcerned that he was just stabbed by a dart flying from the dragon eye.
- Never Mess with Granny:
- Gobber fears Gothi's whacks when he misinterprets her drawings.
- The Snow Wraith learns this the hard way when Gothi attacks it and whacks it with her stick.
- Not Now, Kiddo:
- Dagur does this when Savage sees Hiccup approaching and tries to warn the chief. When Hiccup predictably steals the Dragon Eye, Dagur pulls Never My Fault and blames Savage.
- Hiccup also does it when he'd rather stay in a snowstorm to get a Wraith tooth, and Gothi tries to show him that one got stuck in her stick.
- Scars Are Forever: Gothi has a scar on her arm from when the Snow Wraith bit her.
- Take the Third Option: Hiccup saves his friends then using Toothless' amazing speed goes and steals the Dragon Eye back.
- Trademark Favorite Food: Gothi loves Gobber's Yak noodle soup.
- Unusually Uninteresting Sight: No-one blinks an eye at the gas in the Dragon Eye giving Tuffnut a seizure, though they drag him to Gothi's to get healed.
- Why Did It Have to Be Snakes?: Snotlout says this almost word-for-word when the eels come back for the trapped dragon riders as the ship is sinking.
