Zak McKracken and the Alien Mindbenders/Peru

Must have done: trained to use the Blue Crystal by the Guru in Nepal and have shredded the Stale Bread in San Francisco.
 * For the second time, you must have been trained to use the Yellow Crystal by the Shaman in Zaire.

Once you arrive to Lima, traverse the randomly-generated jungle maze to exit to the riverside. USE BREAD CRUMPS ON BIRD FEEDER to lure the bird, and when it arrives, USE BLUE CRYSTAL ON BIRD.

Now you must be as fast as possible before the Caponian alien arrives. Fly towards the white figure on the right and enter the left eye. The right eye has a part of the device but it's too heavy for the verb to pick up. PICK UP SCROLL and quickly fly outside and to Zak. GIVE SCROLL TO ZAK and wake up. You should leave the screen before the alien catches you.

You should visit Peru again by teleporting with the Map and the Yellow Crystal. You land at the right eye of the human figure. There just PICK UP CANDELABRA to complete the alien device.
