The girl is then tortured by the toys, making Oopsie Daisy rip open her shirt and bite at her breasts. She is then lead to a iron maiden, and forced in there. Erica's servants activate the trap, and the spikes move forward and kill her. Her blood goes into a well which triggers a demon. Erica becomes bored of life and has another evil plan up her sleeve, using the help of a certain demon she mass-markets demonic toys which appear harmless on the outside, but on Christmas Day all the toys will awaken and kill. When Bael learns of Erica's obsession towards Robert Toulon's puppets he remembers that centuries ago a doctor by the name of Shaun Paul Toulon made a deal with him that he'd hand over his soul for the secrets of alchemy but after Bael came to collect the soul it had apparently wandered deep into a black forest and become lost and entangled with an ancient oak. That very tree was the one Andre Toulon used to carve his first retro puppets.
