The horned miragebok has replaced its ancestor in Huggs-Yokto Savanna. It has gotten slightly larger, and more robust. Living in large herds, their skin color-changing ability has lessened some, in favor of brute strength to choose mates. This is where the horn come into play. Mating rivals fight each other with their horns, though these battles rarely result in injury. Interestingly, both sexes sport horns and will fight against the same sex for potential mates. What determines which sex does the fighting is the ratio of one sex to the other; the more popular sex bring the one that fights. Their vestigial limbs have now disappeared completely from view, as well as their front knee-claw. Their foot claw has also drastically reduced in size.
