Faking His Death

[UncleChester]

That's somewhat disturbing. I wonder if it's a voluntary response. "Respawn" is an excellent name for him though

I recently ran across a Green frog, Rana Clamitans, that had near-pitch black eyes (picture is attached). Its body was the darkest I had ever seen though, unlike your little Gray whose appearance is otherwise normal. I have no idea what causes this.
