An ?unexplainable hallucinated style that appears rarely in Epitaph's FurryToonMix XL-Illustrious-V2 model

While the prompt is a classic case of newbie token abuse, and is very critical to A1111's infinite prompt chunk breaking method as well as the tokens (slight differences in the posprompt will lose the style, less-so in negprompt), to have this this pop-up out of nowhere while you're generating regular flat-color 2D Furries is a bit of a shock :) I've got totally no idea of what artist/style it is trained from. The sources in Epitaph's model don't give any leads either.
