Several animated stories precede the Riders of Berk storyline and establish characters and information for it. These include:

Mildew leads the village to near revolt when Toothless appears to be attracting a vicious lightning storm, claiming that Thor is punishing the village for taking him in, and that the Night Fury must be banished.
When the Whispering Death, a vicious tunneling species of dragon, comes to Berk, it becomes clear that he and Toothless have a long-term grudge to settle. The only problem is that Toothless won't let Hiccup help him, and thus he's unable to fly.
A falling out between Ruffnut and Tuffnut leaves their Zippleback, Barf-Belch out of control at the worst possible time, as Berk is visited by Dagur the Deranged, the deranged chief of the warlike Berserker tribe.

Barf and Belch are Tuffnut's only guard when he gets caught in an old dragon trap in the forest. Things go from bad to worse when Tuffnut is faced with not only a large Typhoomerang, but a deadly forest fire that soon threatens him and both the dragons.
When the dragon riders discover a frozen Skrill, a lightning‐powered dragon revered by the Berserkers, they scramble to get it off Berk. But when the Skrill is thawed and unleashed, Hiccup and Toothless must battle both the Skrill and Dagur’s Berserkers.
Hiccup, Ruffnut and Tuffnut must infiltrate Outcast Island and contend with the new alliance between Alvin and Dagur, who wield the fearsome power of their combined armada, along with the deadly Skrill.
