Alright, so the Christmas Season is upon us. That means the Christmas event is closing in too. For the latter, I've managed to get a pet idea in mind.
The Snow Golem from Minecraft.
This has nothing to do with the crappy "Minecraft good!!! FARTnite bad!!!" meme. The Snow Golem always gave me personally a Christmas feeling. It can't speak but it can move just fine. I think it would be a perfect fit.
