Traits

Spiked horns can replace the fluffy cheeks or be added in between the fluff. An Isomara can have between 1-3 of these horns on its cheeks/jawline.

A variant of the spiked cheek horns which have webbing connecting between and sometimes the face. There can be 1-3 spikes; if only one spike, there needs to be a webbing connection to the face.

Small ears that are folded over the scalp. Isomara with fold ears often trim the inner fur tufts to avoid hearing impairments.

A hybrid between the fold and perked ears. Flop ears have full movement, but the tips lack any nerves and muscles for movement. The ends tend to flop around and cannot stand up.

Large rabbit-like ears, and velvety soft to the touch. Isomara can freely move them up, down, and all around. Tieing them up and out of the way is quite common and fashionable.

Long, thin antenna with a bulb at the end. These bulbs can glow in the dark. The bioluminescence can be controlled by the goom.

Nibs but with soft, comb-like hairs. These are purely for looks; however, they can be as great tickle weapons. 

String of soft leafy antenna, they can be as long, if not longer, than the length of the goom.
