It twitched and wiggled in so subtle a motion that the girl most likely could not feel the motion of its movement. It also dimmed the light that lit it from within and, once it reached the seam of her pocket, it dropped right out and started rolling away.

Just keep rolling, just keep rolling, just keep rolling, rolling, rolling.... down the corridor and through the hall, to somewhere else it goes!
