Toy Hell: Nightmare in the Scream Factory was a haunted house at Universal Studios' Halloween Horror Nights 1996, located in Nazarman's. The house was set in a toy factory which was abandoned due to being possessed. The toys that were left behind would come alive and kill factory workers.
Little is known about the contents of this house, but a leaked concept page reveals that there was a "Cobbling Room", in which the guests would hear a surgeon's saw cutting through bones and the screams of the person it was used on. The room was filled with bloody human and toy parts as well as buzz-saws and other, similar equipment. A mutilated corpse hung across one wall, and in a corner a demonic clown was chopping up a hapless victim.
At this point, a strobe light would blind the guests and a bloody, shrieking creature would burst out of the corpse as they moved on. They would see a meat grinder painted as a clown car with the remains of another victim coming out of it as they continued to the next room.
