Snow beast

In the cancelled Warcraft Adventures, snow beasts or ‘’’snow creatures’’’ were white-furred, beastial creatures that dwelled in the Alterac Mountains. They appear as a distinct creature from the more upright wendigo - they look more like small versions of the barely humanoid giant yeti seen in Wrath of the Lich King.

Speculation
They may be early versions of the wendigo or sasquatch, or a completely different species altogether.
