1 - 3: Pooka!

A struggling actor gets a holiday season job as a Christmas character in a plush suit to promote the hottest toy of the year, "Pooka." At first it's a fun and friendly distraction, but he slowly develops two personalities–one when he's in the suit, and one that's outside it–as Pooka slowly starts to take possession of him.
