Me and boyfriend heard a large noise and looked towards the basement steps and saw nothing. Then we heard a bouncing ball. We looked down the steps, but saw no ball. We both went down there and looked everywhere but we found no ball. He went up the steps and I stayed down. I sat where it might have been, didn't see anything, and went upstairs. Came back down, and the exact spot I was sitting in, there was a snake skin. No snake, no ball.
