Yetis are the main inhabitants of the planet Frosthool. While they're not allies with Mortimer directly, Keen will be walking into a snowball fight that's lasted nearly a century with no end in sight. The Yetis will see Keen as just another enemy, so watch out! The Yetis are a race of hostile beasts, they are extremely dangerous, and love to hurl stunning snowballs at each other. Their snowballs are composed of a mysterious substance, capable of stopping Keen's attacks. It's better to avoid than attack a pack of these creatures!
