Hiccup is given the responsibility to integrate dragons into the village of Berk.

With the dragons living peacefully in Berk, Gobber's job of making weapons dries up. Feeling lost, Hiccup tries to help his tough, clumsy dad find a new job.

The farm animals are so terrified of the dragons that they have stopped producing any food for Berk. The Vikings must help before the winter storm comes and they're left hungry.

Hiccup finds an injured, rare baby dragon in the woods, making Toothless jealous. The baby's mother makes her way toward Berk to find her lost son.

The dragons are blamed for causing problems and are forced to leave before they find out the true culprit. Hiccup suspects he knows who that is.

With no dragons left in Berk and the armoury destroyed, the island is vulnerable to attacks. Hiccup tries to prove the dragons' innocence, before danger strikes.
