Unibrows

Intensely territorial creatures, wild Unicorns and Unibrows are bitter rivals.


Edit: Sometimes, Unicorns and Unibrows put their differences aside, resulting in the rare Unibrownicorn. Unfortunately, its mere existence is such an aberration (even by mythical creature standards) that it is usually molecularly unstable and prone to spontnaneous implosion, often resulting in the creation of black holes.
