A boe appears as a small, perfectly round sphere roughly one foot in diameter. Although it seems to be solid at its center, its edges are hazy and semitransparent, similar in this regard to a small cloud or a puff of smoke. A boe's only other features are a pair of dimly-glowing orange eyes, which it often keeps closed to help itself hide. A boe can be either stark white or pitch black, and is almost always found in a swarm of other boes of the same shade. Mysterious but Simple.
