Plastic screw? Where does this go?

[Tony in Texas]

I found this rolling on my floor mat under my feet. I was like, this had to fall out of somewhere. I can't find where it came out of.
Anyone know where this probably popped out of?

check the bottom areas of the plastics and doors? that looks like something from the feet area.

My dog found the exact same thing, maybe a bit longer, on the rear floorboard. I also cannot ascertain where it belongs

underneath the front seats are threaded studs that stick up through the carpet and these hold the carpet in place. kinda hard to have one come off might be an extra, part left behind or someone removed the carpet at one point

This is an essential screw between engine, frame and transmission, whithout it, Raptor will be cut in two parts to the next speed bump.
Sorry, it was tempting...
