We all know the 4 Pac-Man ghosts, correct? Blinky, Pinky, Inky and Clyde? Well, the truth is, Namco intended for 5 ghosts to be on-screen, but considered 5 ghosts at once to be too difficile. In many flash recreations of Pac-Man, however, either Inky or Clyde is replaced by a green ghost. This is due to an urban legend stating that when the secret Konami code "666" is entered into Street Fighter II, the original Pac-Man arcade cabinet can be played upside down and the 5th green ghost will be onscreen. Going through the game's code reveals that this ghost was indeed named "Shitty Titty Walrus."
