I'd probably make deer noises since I'm more deer than fox, and be really excited and look at my Digitigrade legs bc hooves. I'd have a difficult time explaining to my family what was happening to me, but I'd be overjoyed and then probably go hang out in some trees.
If you became your main sona, yet you have other sonas that change with your mood or appearance, would you change to that sona if you felt or looked a certain way?
