They expel most of the water in their tissue, and then reinflate with new water. It's called water-changing. Since they are mostly water, they can shrivel up pretty small, and it can be rather alarming.
As long as it attaches its foot, just be patient, it will fluff up again. They like to wedge their foot in a crack or crevice in the rocks so that's where it will likely end up.
