Hint: Pacing lizard at title screen:
Go to the "Cheats" menu and watch the "Art Gallery" presentation. After "The Turok Team" picture, it ends and begins to cycle again. Return to the first main menu and wait for about five minutes. From the left, a small green lizard will walk along the bottom of your screen, with a picket sign that reads "Lost Land or Bust!!!". When he reaches the right side of the screen, he will turn around and walk the other way, revealing the other side of the sign which reads "Start the Game!". He will look over at you a couple of times, but mainly looks at the ground.
