Episode Title:
No Bark, All Bite.
Episode Description:
Angered at the revelation of Johann's betrayal, Stoick destroys everything from Johann's last shipments, including food and medicine. Despite Gobber and Hiccup's insistence, he is unwilling to trust any new traders that come to Berk. Hiccup and Stoick leave Berk to gather willowbark for medicine with tensions steadily flaring between them, but they discover that each island they go to is on fire and its willowbark destroyed. They realize that they are being sent on a wild goose chase and their absence leaves Berk vulnerable to an attack by Krogan, who proceeds to take over Berk with his Flyers. By working together, Stoick and Hiccup are able to free the Riders and their dragons and repel Krogan's invasion.
