A Japanese company — never mind which one — has invented a tail that syncs to your brain (?) and allows you to show the world whether you're scared, happy, or sad, as if you were a dog or some sort of dog-person abomination, like in Lives of the Monster Dogs. To make this gadget extra creepy, speak as little as possible so anyone who says something to you is answered only by the disquieting swish of your artificial tail.
