Heartwarming / Gift of the Night Fury

• The entire short, but especially the titular gift. After being given an interlocked tailfin so he can fly independently, Toothless uses it to retrieve Hiccup's helmet, returns, and then systematically destroys the tailfin, insisting on the old saddle and tailfin - and his bond - instead.
  • Hiccup's original gift is heartwarming in its own right. You can tell that he genuinely sad at the idea of Toothless flying without him and worried he'll leave him behind. But he stays up all night building the tail anyway and doesn't hesitate to give it to him because he thinks it will make Toothless happy. Hiccup can never properly fix himself, but that won't stop him helping his dragon.
• Stoick and Gobber talking about how much things on Berk had changed since the time of their father's. Despite how different things are now that they'd made peace with the dragons, both men appear happy over all the changes.
  Stoick: By Odin's beard Gobber, Vikings spending the winter holiday with dragons. What would our fathers say?
  Gobber: They'd think we'd lost our minds. (Stoick laughs)
  • Stoick's speech to the village:
  Stoick: I never thought I'd live to see this day. Peace, on the island of Berk. This will surely be the greatest holiday we've ever seen.
• The moment he can fly alone with his new tail, what's the first thing Toothless does? Spends days searching for Hiccup's helmet and bringing it back to him as a Snoggletog gift. If a sweeter, more devoted dragon exists, no one's found it yet.
• The scene at the beginning, when a small child (wearing a dragon costume no less) growls at Fishlegs' dragon Meatlug. The dragon responds with a small growl of its own. What does the girl do? She giggles.
• Seeing the Vikings so worried about the dragons leaving is very heartwarming compared to how they used to treat them.
  • Paired with that, the Viking's overjoyed reactions and cheering when Hiccup returns with the dragons and all their babies. He's come a long way from being the village outcast.
• When Hiccup decides to leave the nesting dragons to come back when their ready, he asks Hookfang for a ride back to Berk. The Monstrous Nightmare is more than happy to accommodate him, a far cry from his behavior when they first met.
  • When they realize Hiccup's leaving, all the dragons of Berk and their babies eagerly wish to follow him.
• The second kiss between Hiccup and Astrid at the end when she's trying to cheer him up over Toothless not returning with the other dragons. She tells him he still did a wonderful thing by bringing everyone else's dragons back then just kisses him on the lips and hugs him tight.
• Hiccup and Toothless's reunion. First Toothless creeps into the hall, his eyes literally lighting up when he finds Hiccup. Then when Hiccup turns around and see's him (helped by an enthusiastic Astrid), they run towards each other and have a huge hug in front of everyone.
  • All of Hiccups dialogue in that scene, from the joyful "Toothless!" when he first see's him to thanking him for finding his helmet.
  Hiccup: That's where you've been? Buddy... thank you, you are amazing. (another hug)
  • When camera switches to the high-up view, it shows Astrid going to hug Toothless just before it goes to the next scene.
• At the end, when Hiccup and Toothless are both freefalling, Toothless reaches out and playfully spins him around.
• Hiccup's closing monologue: "Winter in Berk lasts most of the year. It hangs on with both hands and won't let go. And the only real comforts against the cold are those you keep close to your heart. Turns out, that was the best Snoggletog ever. That year, I gave my best friend a pretty great gift. He gave me a better one."
