thank u! and sort of!! they can have features that would resemble those of another animal (like wing or a snout that resemble a bats like u said ahh) but the general shape of the body specifically should stay mostly the same! so u can add batlike features as long as the anatomy doesn't change that much!! mostly everything is acceptable; tho if u want me to look at your design for further clarification i can!

also only wind capkems can have wings that have capsules inside of them! (empty capsules tho) other capkems can have wings, but without capsules inside of them ^^ (thought it might be useful bc u mentioned a batlike one!)
