You and Carlos are on an expedition to the world's highest mountains in the remote kingdom of Nepal to search for the Yeti, otherwise known as the Abominable Snowman. Carlos arrives a few days early and goes missing from Everest base camp. A yeti sighting was reported nearby. Did he go after it? Or was Carlos onto the trail of something else? "I know that cry. It's the battle cry of the Yeti! We must get help and come back for Carlos." "Why are they angry?" you ask Runal. "Too many people have tormented them. We must go."

If you stay at the wreckage, hoping for help, turn to page 57. "
