Many mobs other than frozen zombies that inhabit the ice cave

The implementation of Ice Caves was announced at Minecraft Live, along with the reveal that "Frozen Zombies"—a variant of the standard zombie—will appear there. However, personally, I think it would be nice to have other unique mobs as well. Examples include the Yeti (a neutral mob with a low spawn rate), the Wendigo (a hostile mob), and the Iceologer—a hostile mob that previously lost a mob vote; were it to be added, it would likely appear in its own dwelling, such as a cabin.
