Costume help wanted!

I know a lovely person who is brainstorming how to dress up as a water bear.

Why a water bear? Well. The water bear is an impressive creature. It can survive all sorts of things the rest of us cannot. Here is a video (I believe it autoplays when you click, just FYI) about "the most extreme survivor on the planet." It is also tremendously cute, while managing to be sort of tremendously ugly.

Slog wisdom is needed, therefore. How would you devise this costume?

Here's Google's slew of water bear images.
