Normal wolf represented by head only because I kept fucking up his pose.

Pereneathean wolf is some kind of mutant killer deer that jumps and run very good, their fur is greenish-grey with yellow, orange,brown and red spots, sometimes they have black and red stripes due to bark of plants on Pereneath being this color; eyes are olive, green, dark yellow or solid black.

There are multiple species of these wolves - here is a run-of-the-mill "grey" wolf,but there are "polar", "desert", "marsh" and even "river" wolves.
