You know how when you conquer a lot of land and if you are vampires you see diamonds or whatever they are. I think they're called race skins. Pumpkins when they start to expand you see a bunch of leaves or flowers i don't quite remember. Reptiles you see a different one too.
Lopdo you should let there be an option to buy different skins.
note: if you know what i'm talking about then yay if not ask and i'll try to answer my best
