This would allow the user to further customize the Ears/Tails (this time in the form of different, more varied shapes), kind of like a sort of training wheels or "guiding lines" for beginners such as me, to help guide where to draw - especially for those who have barely any knowledge on how to draw outside of the base Minecraft skin model (the one with no Ears customization). These more varied options basically function the same as the non-rectangular Claws protrusions do.
