Was it possible for a Fiosioc or a Brokt to be covered entirely with fur/hair? Same with Yinvahts with feathers?

All fur Fiosioc and all feather Yinnies, yup! It’s just not all that common. All hair Brokt? Not too likely, but they can have a LOT of hair. Which isn’t all that comfortable for them, Brokt hair is very tough and abrasive, like straw x,D It can appear fluffy but when touched or petted, it’s not a good time. 

Havok’s hair is like this actually; he goes out of his way to find conditioner for it x,D
