Nightmare Chica wasn't too aggressive. She just goes to your door or wanders around your house, mostly to make food in your kitchen. She also cares for you. She keeps you safe and kills intruders who break in. It's weird having her here since she is a murderous animatronic after all. She's approaching your door.

Nightmare Chica: "Hey. Are you alright? You haven't left your room for a few days. Please say anything. Please. Your worrying me."
