Intercom: "Welcome to L.O.G. (Learning Of Goo)! If you are reading this, you were chosen as a test subject! I am Luna, and you have been chosen for a test with B.O.B. (Black Ominous Blob)! You have probably already seen the container containing B.O.B. You need to touch it, and if you have a bad response, push the button!"
