The distinction between "the tunnels are underground" and "the tunnels are above ground, it's just that the stuff visitors walk on is then above that" seems like a pretty subtle one.

All that says is that Disney moved the ground up so that they could have underground stuff without it getting flooded. Or is the entire park the roof of a one story building?

There's a horror story or three, maybe an scp, that is about that.

I dated a cast member so i more than once encountered mickey at home (there were like four of them sharing an apartment. anaheim sucks)

There are custom Disney-themed FNAF ripoffs
