B-43's Speed: Stationary (Randomized when Moving; Fast to Hyperspeed) B-43 will start at B-000. In 3-4 seconds, it will start moving and it's sound's pitch will rise up. It will then stop moving and it's sound will go back to normal. This happens alot of times. It despawns when it hits the door that leads to the next room.
