Boe (5e Creature)
From D&D Wiki
Tiny aberration, unaligned
Faint Appearance. Aside from its faintly glowing eyes, a white boe is indistinguishable from fog or snow, and a black boe is indistinguishable from soot or shadow. Any boe has advantage on Dexterity (Stealth) checks made to hide.
Slam. Melee Weapon Attack: +1 to hit, reach 5 ft., one target. Hit: 1 bludgeoning damage.
Several black boes.
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 but 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. Boes seem to defy all limitations of normal living creatures, as they spend virtually all their time sleeping or hibernating in dark crevices. A boe may periodically reproduce by splitting into two identical twins, seemingly by magical means. If left unchecked colonies of dozens or even hundreds of boes can all rise up from a single nook or cranny. Although they mostly leave other beings alone, any foreign being that approaches a boe colony is attacked—although the best attack a boe can manage is a feeble hopping tackle.
Boe Nature. A boe doesn't require food or water.
