That's not Santa ...that's the Wendigo! 

On the dark cold wintery night, the Wendigo took his undead reindeer and flew thew the air on a bone sled, dropping off his Ghoullotine goodies among many backer's houses! 

How... kind? 

The Wendigo isn't known for being charitable, but maybe this is a cruel act Trixy is forcing on him, for beating his ass at his own game.
