Skrill

The Skrill is a dragon appearing in the film adaption of How to Train Your Dragon. It is seen in the Dragon Manual while Hiccup looks for more information on Night Furies.

This dragon has large wings, a spined back and tail and a large mouth. Dandelions are supposedly its favourite food, but eating the flower weakens the dragon's oily breath.

The spines on the Scrill's back and tail are sharp enough to cut with the slightest abrasion, and despite the holes in the Scrill's wings, it is an excellent flyer. Seemingly, it resembles a Night Fury in flight. Like the Monstrous Nightmare, its locomotion resembles a pterosaur, which uses its large claws on its wings to walk and run on land.

As with most of the dragons in the manual, it is listed as being "extremely dangerous" and the manual instructs readers to "kill on sight".

The Scrill is featured in Book of Dragons. It is said to only come out during electrical storms, and that it's entire body crackles with static electricity. Just being close to a Skrill is enough to make a person's hair stand on end.
