Woolly Howl
The fine dark scales on the back of this blizzard-loving Strike Class dragon are often mistaken for fur at a distance, but this dragon is far from cuddly.

The Woolly Howl's pale belly lets it blend in with the cold white clouds in the sky. It uses this cover to launch a literal hailstorm of ice balls

Snoggletog Wraith
The rarest of the Woolly Howl breed, this Dragon only appears on the eve of Snoggletog. According to legend, sighting one guarantees a snowy festive day.

Behavior and Characteristics
As a Strike Class dragon, the Woolly Howl is extremely fast, powerful, accurate and intelligent. In the game Rise of Berk, the Woolly Howl and Snoggletog Wraith flies faster and responds much faster than many other dragons. An addition to that, the Woolly Howl spins every time it is called, similar to Toothless in the game, and flips over when the call is over. Meaning that this dragon is also extremely agile.

It has a dark brown coloration on its back, and a pale brown coloration on its belly. It's tongue is purple, with a red "V" shaped mark in the center. It's claws and eye color are also purple. It has a small horn on its head and one under its chin. There are no spines or spikes along its whole body. According to the size images, it is relatively bigger than the Night Fury and the Skrill

Snoggletog Wraith
The Snoggletog Wraith is covered in white scales, which in a distance, also looks like fur. It's wings and tail fins are green in color. While its tongue, claws and eve color are blue. It's neck, front legs and tail are covered by a red and yellow color of its skin that looks like Snoggletog decorations. A red colored pattern that covers its tail fins resembles a red ribbon. One could say that the Vikings of Berk used decorations for Snoggletog that resembles the Snoggletog Wraith's unique skin color, was because they were inspired by its unique colors and used it for their own festival.

 * Though this dragon is extremely fast and agile, it's bulky shaped body and larger size may make it harder to maneuver better than a Skrill or a Night Fury.
