What is the Santa monster?

[Imp]

This was easier in AD&D: anything with treasure type H.

(so, a dragon, probably)

 

[DrunkonDuty]

Goblins. They come sneaking down chimneys with thoughts of the looks on the little kiddies faces.

 

[Whizbang Dustyboots]

A fiendish satyr.

For those who prefer the Krampus.

I spent three years in Austria growing up and totally forgot about him. Thanks! I'm going to be incorporating some of the companions into our next Midwood adventure. (Not set in the winter, but fortunately, up on a snow-covered mountaintop.)

 

[Voadam]

A right jolly old elf.
