Bring them both inside the hostel. USE the token on the metal plate to the right of the airlock door, and PICK UP the burnt-out fuse. Then, USE the fuse from your van in the air lock fuse box, and PUSH the button, closing the door. Next, PUSH the button by the door on the right wall, and send Leslie into the dormitory. (Melissa is a little too squeamish.) Check out the locker by the door and PICK UP the little strip of yellow vinyl tape. OPEN the right side of the cabinet, and PICK UP the flashlight. Move to the right and PICK UP the covers, revealing a dead alien shaped like a broom. Finally, PICK UP the ladder in the far right corner, and leave. WALK both the girls to the right (past the van) to the Giant Face and a door that has three buttons on it. Set up the ladder under the highest button, and send one co-ed up the ladder, while parking the other by the lowest. Now press the buttons in the order indicated by the dancing natives in Zaire. This will open the door. Take both girls inside. Inside you will find two huge statues and three massive doors. On one of the statues will be strange yellow markings. READ the markings and copy the symbol down (they change from game to game). This is the symbol Zak needs to draw on the Mexican statue's base to get the yellow crystal shard. But first there are some other matters to take care of in the Great Chamber. Your oxygen will not last forever, and it might be nice to see the girls' faces. Let's find the air conditioning unit.
