Crystalings [Interest Check]

Edit: in process of making world/ discordd

aaaa I've been kinda bored so I tried to create a species called Crystalings (closed species?). As you can infer from their name, they grow crystals on their bodies. An example of how a Crystaling would look is here; also please tell me if a similar species like this already exists!

The trait sheet might not be too exact but here are the current traits I've thought of so far; common (blue), uncommon (green), rare (red)

About Crystalings

They like to live in caves or such (or wherever crystals normally grow) and they can eat human foods however prefer eating crystals (as so, the currency we will be using is crystals). Crystaling children are usually born with tiny crystal stubs however as they grow, their crystals on them grow along as well

For now, Crystalings can be any color, however their main color palette will depend on when they were born (or more of created). We will be using birth crystals to decide the type of crystal and color (ex. March is aquamarine, September is sapphire, etc.).

I'll probably add more info onto this species as well as create an actual thread/ world for them if enough people are interested in them; anyways thank you for reading and any suggestions/ bumps would be appreciatedd ^^
