FNaF 4 References
1983
Close-up of one of the Observatories from the Breaker Room map, this one being the FNaF 4 Minigame layout.
If you type 1-9-8-3 into the keypad while in the Private Room, it'll reveal 3 images from FNaF 4; The FNaF 4 Bed, Bedroom, and Plushtrap's hallway. This doesn't work during Custom Night's modes with Funtime Lolbit. However, due to this Easter Egg being a part of the Fake Ending and Custom Night it is Non-Canon. However Scott have clarity that this the actual date when FNaF 4 takes place.
Breaker Room Map
If you look closely on the Breaker Room map when restarting the power you can notice the FNaF 4 house layout, minigame layout, and Plushtrap's hallway layout.
Blueprints
Randomly when entering an area or booting the game a blueprint of one of the 4 main animatronics will appear on the screen for a minute or two.
Funtime Lolbit
There is a incredibly small chance that Ennard's mask in the Primary Control Module will be replaced by Lolbit's head. This may happen when you die to Funtime Foxy by a set number of times often, similar to Minireena's Easter egg from the Primary Control Module.
Yenndo
When using the beacon in Funtime Auditorium on Night 3, the player has a very rare chance to encounter a bear-like endoskeleton named Yenndo, instead of Funtime Foxy.
The endoskeleton's appearance seems to look identical to Funtime Freddy's actual endoskeleton, though with few differences - A lack of "face-frames", wider eye spacing, having both hands (which would include the lack of Bon-Bon), and most noticeably yellow irises.
Nose Honk
Like in every FNaF game your able to honk a Freddy's nose, in Sister Location you can honk the Fredbear plush's nose, this is only possible in Custom Night.
