Hotburple

The Hotburple is a new Boulder Class dragon that appears in How to Train Your Dragon 2.

Appearance
Hotburples greatly resemble Gronckles, although they have larger body and wings, with their eyes positioned closer to the snout than to the ears. They can do anything while sleeping.

Characteristics
Like the Gronckles, the Hotburples is amazingly heavily armored species, and has a famous Lava Blast identical to that of the Gronckle, with a highly striking power almost reaching the level of the Night Fury.

Trivia

 * A Hotburple named Grump is Gobber's dragon in How to Train Your Dragon 2.
 * While Gronckles like to eat any type of rocks, Hotburples prefer metal ores more.
 * It is possible that the Hotburple is actually a subspecies of the Gronckle.
 * It is said, however, they are still somewhat related to Gronckles.
 * It is unclear whether any other Hotburples share the half-closing eyelids of Grump.
 * As seen in a Hotburple photo, Grumps teeth is thinner and maybe a little bit sharper than Gronckles teeth.
 * As seen in one of the photos, where Gobber is flying on Grump, it seems that Grump is sleeping. This might mean Grump can do certain things while sleeping. If so, it may be the special ability of his species.
