Changing into something else for the game. The magical size bracelet chapter 20 by SatireMarker

Tread might have been changing into a different pair of shorts or underwear for the game, but it was impossible to know exactly what he was doing. The layers of fabric alone were thousands of times wider than you were tall. But perhaps this was an opportunity to explore the rest of the nanoworld now you weren't surrounded by Tread's shorts and pants.

Or perhaps it was time to grow back to a more normal size, since you couldn't really do anything like this.
