A request from Terabetha, it's the character The Stoat (top left) from my story Divine Protection infecting a fawn, and then at the bottom is an example of an infected stag.

"Quad looked to the center of the crowd, where a large weasel-like creature had her eyes fixed upon him. The Stoat's body was completely black and slender, and Quad knew this was the source of the infection."

The inspiration for the Stoat, ironically, is from a plush animal I own.

But anyway thanks for the request Terabetha!
