Christmas is coming, and santa has to be part of this game somehow. My suggestion? SANTADUKE! Vanaduke, ice themed and with a new textbox! "More wolves after santa's workshop? My undead elf helpers shall destroy you utterly!" Elf helpers are the zombies, but ice themed. At the end bits with those charging guys, if you add antlers=reindeer! Santaduke is very much like vanaduke, although ice themed and with a santa hat. I do not know if this is in good taste, but this is what I want for christmas.
You're TOO LATE to make a Christmas suggestion when the update is coming in a few days!
Plus Nicks twitter hinted at an Impostoclaus.. idk if he really means it buuuut..
OH AND last year during beta, Vanaduke had a christmas hat (I THINK! I just remember almost every monster having one)!
