Hey, guy who beat 4/20 mode here. Yeah it’s mostly rng. Just listen for the laugh, make sure she’s there and wait roughly 10-15 seconds then close the door, when she laughs again open it. Audio cues are key, footsteps means someone is at the door so you don’t have to waste battery on lights. Only use the camera to check if foxy is running or Freddy is in front of your door. Other than that you just gotta be quick and lucky.
