Horns are hard protrusions. Leeches have them for a variety of reasons, for example: For protection, for hunting, for beauty and for mimicry.

Horn traits can be slightly altered as long as the basic premise remains. (For example, uni can be ribbed, halo can have a notch in the middle)
Horns can be mixed and matched, but only two types can be mixed (for example uni + rhino, or tri + slick)

Leeches can only have 1 set of horns without a myth upgrade

Horns are an optional trait!
