How to Train Your Dragon
(2010)

Hiccup and Toothless defeat the giant dragon by causing him to nosedive into the mountain a la Monstro. Hiccup falls off, but Toothless saves him. Hiccup is shown to have lost his left foot, but has a new dragon harness that perfectly compliments Toothless' missing left tail sail, of which a new one has been made.

The remaining dragons show their gratitude by helping the vikings rebuild the village.

Thanks Herbmeistr!
