Drakryttarna från Dräggö

In the aftermath of the events of the movie, the kids are enjoying their new lives with dragons, but the rest of the villagers aren't so sure. Hiccup and his friends have to find a way to train the dragons to live in peace with the rest of Berk.

Now that the dragons have assimilated into Berk, just about everyone seems to be better off. Except for Gobber, who made a career of building weapons to fight the dragons. Hiccup takes it upon himself to find a new role for Gobber in the new dragon-friend

As the dragons become more comfortable as a part of Berk society, the livestock are becoming less comfortable - fire-breathing predators are, after all, around every corner. As a result, Berk is running low on eggs, milk and other food supplies.

While out flying on their dragons, the kids stumble upon a small dragon with an injured leg. They bring it back to Berk - no one has ever seen this species before, and everyone loves the new dragon, even Stoick, who names him Torch.

When the dragons are blamed for a series of damages around the village, Hiccup and the kids form the Dragon United Monitoring Brigade (aka DUMB).

After the dragons are banished from the island, Hiccup searches for evidence to prove their innocence.

A rogue sea dragon is attacking Berk's fishing ships, but Stoick and his men have been unable to pursue the dragon by sailboat. Hiccup tries to convince Stoick that he needs a dragon of his own for just such occasions.

When Stoick has a portrait of himself and Hiccup painted for the collection in the Great Hall, Hiccup ends up depicted as a strong, burly Viking, not his usual skinny self.

Trader Johann comes to Berk, bringing with him new and exotic goods that the people of Berk hurry to trade for. But soon, the dragons begin sneezing and getting sick.

A mysterious girl, Heather, washes up on the shores of Berk. Proving herself a valuable addition to Berk, she wins the affection of everyone except Astrid, who notices Heather is particularly interested in flying dragons and in the Book of Dragons.
