It has traction in the pony community too. Derpi is the only site/community I’ve seen to not call it feral and there’s just a gap where pony kind of fits but not really. I’m not against calling it quadruped either, mind you. I do however feel like if it’s not feral, feral should at least be aliased into it because the current meaning is largely useless/undertagged (and misleading to most people) and that meaning moved to something more obvious to its purpose.
Right now I’m mostly focusing on the tags I have in front of me rather than creating new ones. Serpentine might not be a bad idea though, and yeah hybrids and sea creatures are kind of a pain to work into it. It’s still very much an early work in progress. I only have ideas written on paper, none of the actual planning stages have gone through yet and those would be brought up in the forums. I mostly mentioned it here in an unofficial way because I felt like it would come up.
That being said I’m definitely open to ideas and this is good feedback for later use that I’ll keep in mind. :)
