And finally! There is a reference from the Mermeron species!
There are some circles with numbers, it's basically some aspects that you can change when you are drawing (or something else-)

1- You may make your own LED design and choose you favorite color for it;
2- You can put how many tails you want;
3- Fingers must be only three;
4- You can put a pair of antennas, or not if you want;
5- Put what you want on the back;
6- Mouth is optional, they don't really use it, but if you want it ^^.

That's it, I want you all enjoy my species.
