Mystery Leak

I have some sort of leak going. In a regular house I’d have a good idea where it was coming from and what to do about it, but in a mobile home, I’m baffled. Water coming up through the floor in weird places.

First it was the closet pictured above. I traced that to a dishwasher two rooms away. Now it’s in the hall. There is no basement for it to be coming up. It might somehow be making it’s way from the roof, but it isn’t dripping through the ceiling, it’s welling up from underneath. There are not pipes in the area. it isn’t a spill.

Any ideas what the heck is going on? I’m baffled.
