Dude imagine a hardmode sister location
Night two: Bidybabs are assisted by Electrobabs that will turn off your flashlight at random, clicking their glowing eyes makes them go away and makes your flashlight work again
Ballora and Music man share a room, Music Man will go closer to the player, crashing his cymbals to the rythym of Ballora's music, making her come closer
Funtime Chica is also present at the breaker room (kinda connecting this with her ucn appearence, with her thinking the malfunctioning lights are camera flashes)
Night three: Yenndo is also present in funtime auditorium (referencing his Easter egg, now as a actual threat) making the player slow by lowering the oxygen levels, flashing the beacon makes it reset, letting out the air, Yenndo will reactivate after the next flash
Bonntte makes her apperence alongside BonBon, you have to click her nose or she will activate funtime Freddy, causing a instantaneous jumpscare
Night four: a broken Security Puppet is seen in front of the player, one of their eyes will start glowing, you have to look directly into one of them to deactivate it, if you don't, you get jumpscared by Security Puppet
Night five: in the real ending, behind baby, the bodies of the technicians, being moved by the Minireenas and Bidybabs can be a threat, all you need is flash the light in their eyes and they will go away
In the fake ending, you have to fight against the bodies alongside Ennard, you have to flash the camera lights in which room they are into to make them stop
