Pooka Collection

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; he slowly develops two personalities—one when he's in the suit and one that's outside it.

A group of thirty-something friends from high school create their own Creepypasta about Pooka for laughs, but are shocked when it becomes so viral on the internet that it actually manifests more murdererous versions of the creature.
