Golden Freddy isn't in the gallery, if you wanna see her scene you gotta do 6/9/6/9, the 4/20 is still for 100%, but not Goldie. If you wanna a tip, for 4/20s.
Hear for footsteps and check the doors for Bonnie and Chica, when you close a door, wait some 2 or 3 seconds later you can open it without needing the lights.
For Freddie when she laughs check if she is in the kitchen, if she is you close the right door, and after the first time you don't need to check her on the camera anymore, cause she will always: "Laugh" > Not on kitchen > "Laugh" > On the kitchen again.
For Foxy, check her room every 3%, when she gets on all fours check every 1%. If you have a closed door you can check her ever 4% and 2% if she is on all fours, since the energy falls quite faster. When she disappears, close the right door and check the Left Hallway camera.
