When you load into the game you will watch a cutscene and will then load into Poppy’s case room from the end of Chapter 1. There’s nothing else in this room so turn around and walk back down the hallway until you reach the room with the doll houses. On the right side of this room you will see wardrobe on its side next to a white door. Go up to the door and open it to enter a new area of the factory.
