This is a video from somebody's Nest doorbell cam, presumably Australia or hell but possibly just Florida that was triggered by what appears to be an infinitely long snake slithering by. Where is it coming from, and where is it going? What is it doing there? I bet that's the same son of a bitch who's been stealing my Amazon packages!
Keep going for the video.
Thanks to Randi, who agrees that is not a door you answer.
