After confirming the existence of the Loch Ness monster, get in the helicopter and travel to the Himalayas. When you arrive there, jump up. You might run into a guy near a tent, holding a pole. When you talk to him, your choices will be:
Who are you?
Can you guide me to the top of the mountain?
If you ask him to guide you, he says his climbing days are over. So keep jumping up the mountain by yourself. Other people will also have excuses if you ask them to guide you, for example a man smoking a pipe who tells you he is cooking dinner.
Climb up to the top, then jump towards the left, and you will run into a man with a big backpack on him. When you ask him the same question, he tells you that of course, because he is a Sherpa and that's what he does. He wants to get going right away.
He tells you that one of you needs to be tied to a ring at all times or the wind will blow you off. He instructs you to run ahead and tie your rope to the next ring. He will catch up when it's safe. Go left and reach the ring. The Sherpa then catches up with you. Keep going left and climb to the next ring, wait again for the Sherpa to come and tell you that he is tied. Climb to the right and repeat for two rings, then climb two more rings to the left. Then again jump left and reach the last ring. Wait for the Sherpa to catch up, sometimes it will take him more time to climb.
Go left and reach the monastery area. Enter the monastery, then go right and talk to a monk there. Your options will be:
Can I please have the Yeti Scalp
I'd split the million dollar reward with you
Please, I need to find proof of the Yeti's existence
Choose the third option. The monk says that she sees you are a seeker, and gives you a lantern to help light your way.
You receive:
Unlit Camping Lantern
Strike a match to get a light going
Go outside. Light the lantern. If you climb up, you will run into a monk who says he cannot let you pass. Your options will be:
Please, I'm trying to find proof of the Yeti's existence
Really? What do I need to do?
Ask the monk what you need to do. He tells you that you must beat him at a little game:
The Hunters are after the Yeti! You must move your game piece (The Yeti) safely across the board without being trapped by the Hunters. You can only move one space each turn. Safely reach the other end of the board and you win. Get trapped by the hunters and you lose
Play the game, and avoid being trapped. If you fail, you can play again. Try moving your piece left, left, diagonally left and down, diagonally left and up. Once you beat the game, he lets you through.
