Ice mobs

In biomes with any hint of the wintery side of minecraft, the main mobs are polar bears and... No that's it. There are a few ideas of ice biomes and the water could have something like lave but it's more longer to die, like hypothermia and like the strider there could be a mob like that but you can tame it and make it sit so you don't have to craft leads and try and find it. If tameable it MUST be cute. They drop ice.
