Murrayball mini-game
Go to the Palace Of Prostheses, use the filing system, and enter "Monkey-Pumpkin-Bunny" as a code to get the Ryan J. Danzwithwolves file. Look at the file, pause game play, then select the "Bonus stuff" option to access Murrayball.
Note: This must be done before looking for the No-Nosed Man.
