if anyones having trouble with clearing the nights there are a few cheese strategies to hopefully get through it early
Night #1 - Straight forward, just run into the rooms it asks you to and then crouch in front of the door till morning, Bonny may not even start moving if you're lucky
Night #2 - The strat i used may take a couple of tries but works fairly well. First, i run straight through all of the tables in front of Bonnie and Chicas stage, the pizza slice is usually hanging off the edge of one of the tables and you can grab it before Chica even starts moving (if the pizza slice isnt on the tables i just go for a reset) after getting the pizza slice i check the office and then run to the arcade area. Theres an air duct on the right lane of the arcade area that leads back infront of the stage but by the time you go through, Chica will usually have just awoken and goes up and down the tables (you cant hear her footsteps so be careful when you look out the vent. Once Chica has walked out of the area i carefully run to the entrance and check the second stage (the cupcake is often in one of the seats in front of the stage) if its not there the last rooms are Foxy's den and the kitchen area inbetween the entrance and the main stage but once you find the cupcake, just crouch infront of the exit and wait till morning
Night #3 - (Honestly easier than night 2 in my opinon)
For starters, the blaster blends in with the carpet and is usually sitting on the ground. Head straight to bonny and look in front of her, if you're lucky the blaster spawns right there. If the blaster isnt there, you can try heading to the arcade room and checking the floor at the very end as it often spawns there aswell (though i'd just reset till it's in front of bonny.) After finding the blaster i run straight to Foxy's den while she's still not active and check the closet left of her, the red hat often spawns on the bench in said closet and if it is there you can easily just run to the exit and crouch till morning. Foxy will wake up and walk straight by the exit but if you're crouched and right against the doors she probably wont mess with you.
those are my strats that work fairly well (though Night #3 worked twice i may have just gotten good luck.
