Note: This only works if you go to Deadeye Dave's shop and get all the free prosthesis. Save the game before attempting this glitch. Go to the Myst 'O' Tyme Marshe. When you reach the gate for the first time after you have gotten the key and the other two items from him put all the prosthesis together and use it. Guybrush will say "it's alive!" then the abomination will fly off screen and the game will freeze.
