MOTION TRIGGER: ENTRY WAY VENT is an animatronic detector

[76561198082717135]

Have you noticed that this particular trigger never works when we crawl through the Entry way vent on Nights 1-3?
When the Hand unit restarts the system on Night 2, we hear it for the first time, though we hear no other motion triggers. So it looks like it triggered when Bidybabs started climbing the vent during the blackout. And motion triggers are heard all throughout the facility, but why is this the only time we hear one of them react to the animatronic?
The second time it triggers is when we crawl through the vent on Night 5. Remember that we already completed Night 4, the Night when a lot of Minereenas crawled inside our suit. And, as Scott hinted on the forum yesterday, the scooper alone wasn't enough to tear out our skeleton and SOMETHING (Minereenas) had to crawl inside OUR BODY to finish everything manually.
So, the whole raison d'etre of the Motion Trigger system in the game is to tell us on the Night 5 that animatronics are sitting inside our body. And entry way vent motion trigger is a special trigger that only reacts to animatronics (or a person with animatronics inside their body).

Maybe after getting scoped Ennard finished the job, but that is a good theory, and might explain the MiniReenas

The motion trigger for the Circus Gallery vent goes off whenever we enter it for nights 1-3. No animtronics on our person back then.

No, I mean the motion trigger in the Entry Way vent (between elevator and control room)
