Minecraft Dungeons:Arctic Fox
The Arctic Fox is a pet mob obtained through the Creeping Winter DLC or the Hero Pass DLC. It is purely cosmetic and does not attack enemies. It will occasionally whimper when stuck or when it takes fall damage and will run up to dropped items. Though it will react to falling, it does not take damage and cannot be defeated. It can also be used to activate the Redstone Golem's mines.
