Grump

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

History
Grump was used to eat the scrap iron at Viggo's Dragon auctions until he met Gobber. He then helped Gobber and Hiccup's riders in escaping the dragon cages. He then took Gobber and went with him to Berk.

For the next couple of years, he worked at Gobber's Blacksmith Shop maintaining the fire there.

Appearance
Grump is a Hotburple with brown and grey scales. He is rather unintelligent looking and lazy.

Personality and Behavior
Grump is extremely lazy and spends most of his time sleeping. But he is loyal and affectionate with his rider Gobber, a lot like a cat. Although Gobber complains (very hypocritically) about Grump, they are obviously really good friends and partners, and are perfect for each other.

Skills and Abilities
As a Hotburple, Grump has much the same abilities as any Gronckle.

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 dozing (sometimes even asleep), airborne, and carrying Gobber at the same time.

Trivia

 * The bludgeon on the tip of his tail and Gobber's new, mace-like, hammer-shaped, artificial arm strongly resemble each other.
 * He seems to take Gobber's commands slowly.
 * Grump seems to like sleeping on people in How to Train Your Dragon 2, although he is mostly seen sleeping on the ground.
 * Grump's laziness is similar to Garfield the cat's own laziness.
