Grimmel's Airship

Grimmel's airship is a contraption built by Grimmel the Grisly to travel across the skies with the aid of his Deathgrippers.

Hunt for Toothless
Grimmel used his airship to travel to the Warlords' base, where he discovered that Toothless is the only Night Fury he has not killed. He eventually used the airship to travel to Berk after all of its inhabitants flew away from the island.

When Grimmel sedated Toothless and his mate, he attached the two Furies onto his airship as all of Berk's dragons charged out of the forest of New Berk to rescue their Alpha. Grimmel responded by aiming his harpoon at the Light Fury and forced Toothless to call off the attack. He then drove the airship to the Warlords' armada with all of the dragons in tow.

As the dragons were caged by the Warlords, Grimmel proceeded to lower Toothless to his employers, only to reel him back so that he could kill the Furies himself. However, Hiccup and the rest of the Dragon Riders flew in and knocked Grimmel away. Grimmel prepared to kill Toothless with his harpoon, but he was forced to dodge the Night Fury's plasma blasts, inadvertently releasing two of the chained Deathgrippers and left the other two flailing about with the greater weight of the airship. Hiccup jumped onto the airship to rescue Toothless and witnessed Grimmel used Deathgripper venom on the Light Fury before he released her from her shackles and rode her back to New Berk. Hiccup began to release Toothless from his bonds as the airship crashed into the sea. Hiccup and Toothless managed to escape in time and began to chase after Grimmel.
