The first one is mousetrap in the breaker room vents, if you click the button you probably close the ventilation. Also there is a warning saying: "this is the central breaker room. any object that enter said room could cause severe damage to the power supply" so if mousetrap manages to get out of the vents it drains your power?

The second one is lucky cat true form??? maybe you fight him in the final night idk, but it is cool

The third one is a scene from the trailer, nothing to say

The fourth is from one of the office, you lift the lever and then press the button to make the lights flick, this would probably be for eddie like in the first game

The fifth one is from turvy's coding panel. Maybe if you do the thing right he will make movements, and looks like the guard finished making it

The sixth one is the ventilation but empty, nothing to say

The seventh one is from a free roam part, probably after you complete a night

The eighth one is also from a free roam part, and looks like the place is a storage, there is some boxes and cutouts, it is probably a storage to the eddie and the misfits theater

Ninth is a free roam part, but looks like you can collect keys to open doors (that could be so cool )

Tenth one is mousetrap in a stage on the breaker room? maybe they are testing him or something

(This game could be one of the best fnaf fangames)
