I love how this came out! I wrote a story about how I became a scurrier, and a friend was nice enough to give him a try!

Here he is in his favorite smart-clothing, clothing made of nanobots and so able to shapeshift, change color, texture, even camouflage or protection from space formed as a full-body suit. But when he doesn't need to do any of that, they often default to just a cute pair of heavily-stretched boxer shorts with little pictures of Thomas all over them. Designed on the near-molecular level to be extremely comfortable and pretty much totally indestructable / infinitely stretchy, to the point that the fatter or more inflated or hyper he gets in them, the better they get!
