Minecraft Dungeons:Arctic Fox

"That's one stone-cold arctic fox. No, really - it's cold out there in the snow!"

- In-game description

An arctic fox is a pet mob obtained through owning the Creeping Winter DLC, Hero Edition, Ultimate Edition, Hero Pass, or the Ultimate DLC Bundle. It is purely cosmetic and does not attack enemies.

Behavior
Arctic foxes 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. The only way to kill it is for it to somehow fall into a pit similar to those in the Obsidian Pinnacle, after which it will die and drop emeralds. It can also be used to activate the redstone golem's mines.

Trivia

 * An arctic fox appears in a tweet from Minecraft Dungeons running in circles, chasing its tail. At the same time, the arctic fox somehow is able to avoid being trampled by the legions of Illagers rushing past it.
