The quest itself is short and sweet, and with only a bit of running around you get the Reindeer Suit and Antlers.
Did we mention we are cute?
We did find a bell that you can /snowball and it rings:
The /snowball emote is super cute, and makes you look super mischievous.
All in all, a fun event. Pretty snow, silly costumes, great decorations, and an easy quest for characters at any level.
