You are inside an elevator that takes you straight to an old children's party place that was underground, but now it is just an area to watch old Animatronics, and observing the galleries, one of the animatronics does not respond to Shock's command, going to look at her area, you hear a gentle and kind female voice

"I can hear your footsteps, I know there's someone here"

You hear ballerina music box music approaching you in the darkness
