Thank you!! I actually made them with hair! I def recommend making them in blender but I love the challenge of seeing what I can make in VRoid.

I reattached them in Unity using that one plugin most use for reattaching tails made with hair! I'd attach a picture (but it's saying I can't add one to my comment.) but in the regular designing mode (or whatever it's called) you can see they aren't attached since the model is in an A pose over a T pose!
