Neptuna may not be part of Aarial's friend trio...

But he is at least acquainted!

Since I don't have a chart yet to explain these statistics, I'll give a small summary what is means here.

Spectarrians evolved from a much older and more primal form of themselves that had four feelers the could tear into their prey, and they did not have eyes, and had massive mouths.

There's Feral-type spectarrians. No eyes. All teeth. Four feelers. Hefty cave dwellers with very sensitive ears. Walks on all fours. Hostile.

Single Cross-type(X). Very slim eyes. Slightly shorter teeth. Four feelers. Mostly walk on fours, but can stand with effort. Mostly hostile, can be trained.

Double Cross-type(XX). Wider to completely open eyes. Teeth small enough to close their lips around, but still can protrude. Walks on two feet. Three feelers. Most non-hostile, some can be integrated into modern Spectarrian society, though under moderate surveillance.

Tame-type. Modern spectarrian. Wide eyes. Short teeth. Two feelers. Walks on two feet. Non-hostile, incredibly friendly.
