Grump

Grump is a Hotburple, and is Gobber's dragon in How to Train Your Dragon 2.

Appearance
Grump greatly resembles a Gronckle, but he has larger size and wings, and his eyes are positioned closer to his snout than to his ears. He is rather unintelligent looking and lazy.

Skills and Abilities
Tail Whack: Grump is shown to be able to fly low and knock people over with his lumpy tail. He is very talented at this, as he can do it while he's asleep, airborne, and carrying Gobber at the same time.

Strength: Grump can carry Gobber and heavy seat settle on his back no sign of struggle.

Trivia

 * The bludgeon on the tip of his tail and Gobber's new, mace-like, hammer-shaped, artificial arm strongly resemble each other.
