How to deal with animatronics: Chica: Active night 1 and onwards. Check for her in the doorways using the lights. If you see her in the doorway, close the door. Bonnie: Active night 1 and onwards. Same as Chica, except can skip west and east hallway. Foxy: Active night 2 and onwards. Check Pirates Cove to slow him down. If he is not there, shut the left door, or you will die. Ronald: Active night 3 and onwards. He doesn't go down the west hallway, and he can skip doors. So if he is in the east hall corner, close the right door.
