Howl-O-Scream 2011

Howl-O-Scream 2011 is a screamer commercial that was aired on TV a little earlier the same year The commercial features a cutesy/creepy song in the background as the camera pans over CG figures and gardens, intercut with people visiting the attraction, clearly scared. But it's not over yet. At exactly the last second, a zombie woman pops out of a patch of roses howling before abruptly cutting off.
