AppearancesRiders search for a way to save the ailing Hookfang. Snotlout broke off a piece of Firecomb, believing it would cure Hookfang, but ended up angering the Fireworm Queen. Though she then used her own fire to save the other dragon.
The Fireworm Queen tracked Hookfang down in hopes he would return the favor she did for him many years earlier. A Cavern Crasher, Firecomb Crasher, attacked the nest, and drove the smaller Fireworms away. In the attempt to fight it off alone, it wounded the Queen. It then attempted to eat the Firecombs that contained newly hatched Fireworms. But Snotlout and Hookfang helped drive the adhesive dragon off, saving the Queen's young.
