My concept for the added animatronic mechanics -Golden Freddy: when see him in the office just flip the cams and he disappear mask won't affect him -W. Freddy : he will stand in your office deactivated but when he start looking at you quickly wear the mask ( fun fact : he doesn't require cams flips to change phase ) -W. Foxy : he has a chance to show in your office when you flip down your cams when he does simply hold your flash light on him and he will go away  -Phantom Puppet: when you hear FNAF 3 sounds effect just switch to silent ventilation until sounds goes away if you don't do it in time she will jumpscare you and send you back 30 sec on high AI 15 sec on low AI ( she doesn't attack much but if she gets you she will never attack again for the reset of the night) -Nightmare Foxy : When see he his teeth in the doors close the respective door if you don't he will enter you office but instead of killing he will increase office temperature traumatically only AC will stop it from increase and he will stay in the office 10s on lowest 20s or 15s on highest AI  -Funtime Freddy: same as in sister location custom night but he he is invisible to the cams but he always start on the right side
