It doesn't seem like you understand how this would be a useful. This is not an explanation for slipping in the water and wrinkling to climb back out, it's for spending long periods, perhaps for fishing or during the wet season, and still being able to grab and manipulate objects.

Sorry, I am missing your point. In the absence of wrinkling, what is stopping me from being able to grab and manipulate objects?

I can do that without wrinkling, even in water.
