Smoke Gets in Your Eyes

When Trader Johann delivers mass quantities of metal to Berk that came from Breakneck Bog, the island becomes infested with Smothering Smokebreaths, that steal the town's metal to build a new nest. With no metal, and especially no weapons to protect their village, Hiccup and the others must find a way to get rid of the rogue dragons, only to discover that the Smokebreaths' appearance was planned as an attack by Dagur the Deranged.
