Infected Woolly Howls

These Grimora-Infected Woolly Howls, along with Infected Deadly Nadders, appear in the Expansion "Rise of Stormheart" and subsequently the "Dragon Tactics" mini-game in the game School of Dragons.

Captured and Infected
These wild Woolly Howls were released by Nikora Stormheart onto Dragon's Edge, followed closely by a release of Grimora which attached themselves to these wild dragons. This was meant to cause havoc on the Edge, for Hiccup's interference in her business. The player then 'battles' these dragons in the "Dragon Tactics" mini-game, which is implied to involve weakening them in order to douse them with saltwater and rid them of Grimora, not actually physically causing them harm.

Free from the parasites, these Woolly Howls are seen flying away from the Edge back to Nikora's ship, though it is unknown why they would do so. Later, Nikora releases them from cages aboard her ship after infecting them with aerosolized Grimora toxin. Again, the player must 'defeat' these dragons in the "Dragon Tactics" mini-game.

Physical Appearance
These Woolly Howls are all identical - the typical Woolly Howl build in School of Dragons in a sort of greyish-purplish body color. Their wings are mostly a greyish-blue and their scale manes are a light mousy brown.

School of Dragons
The Infected Woolly Howls appear several times in the Expansion "Rise of Stormheart".
