Use the whip to loosen the stone ball from the wall in the bonus level, "Return To Peru". After that, go down and walk through the hall of snakes again. Climb over the large wall again, jump to the edge where the stone ball previously located. Push the switches to the right in the following order: 4, 5, 3, 1, 2. If done correctly, a door will open and a room with the miniature Devils Tower model from Close Encounters Of The Third Kind will appear. Also look out of the windows to see a UFO.
After using the mirror to kill Maduk for the first time, go to the bottom of the room where Sophia is floating. Walk through the hole at the bottom and fall down. Return to the point where the level started. "Swim" through the reddish tunnel to the west. Exit the end of the tunnel to enter Monkey Island world.
Activate the makemeapirate, and urgon_elsa codes. Fire the bazooka and something will shoot from it. Run after it until you see it sideways on. It is a chicken. When it hits something, it will explode.
