New Mountain Mob - Yeti

With introduction of the better mountains and snowier snow, I think there needs to be a new mob for this biome. personally, I think going with a creature like the yeti is something that could be really interesting. The yeti would be about the size of an iron golem, and would only spawn on mountains after a certain height/Y-level. These creatures would live in yeti caves, which will be guarded by at least one of these beasts. They would act like some sort of mini boss, similar to the elder guardian, where upon death give you yeti fur, which will give you the ability to craft hiking boots, used to walk over the powder snow without falling in, and keeps mountain goats from ramming you off a cliff and other large knockback attacks due to their grip on the ground.. Also, after defeating the yeti, you can gain access to their cave, where many rare items can be found. A new mob for the caves and cliffs update on the cliffs side of things could really freshen things up, especially a tough hostile one like this, providing a cool alternative to the warden.
