As you're walking through the facility, having found nothing but an airhorn, you eventually decide you should head back, since, last time you checked, it was 5:12 PM. You're walking back down the way you came without trouble, at least until you find me blocking the entrance to one of the doors you need to go through. I'm slowly crawling towards you, intent on absorbing you into my mass, my large body being squished together by the narrow halls of the facility.
