This is a rather common problem. The homeowners suffered from a flooded toilet which eventually cleared up but unfortunately dumped water all over the bathroom floor. This was then absorbed into the surrounding flooring, walls, and the nearby sink cabinetry.
If your toilet is overflowing use a plunger and don't get frustrated sometimes it takes a little bit of time to clear up. Multiple flushes could just make cleanup messier.
