??? mystery frog ????

Tonight we found a frog randomly sitting the middle of our living room. It was a gray tree frog. I brought him outside and let him go. He was covered in soot so we assumed he came in through the chimney, but our chimney is sealed off so i have no idea how he got in. I gave him a little container of water to clean off the soot. I found him a few hours later splatted against a log, sleeping. I named him Ash, though i don't know if i will ever see him again. Good luck Ash! :)
