Whenever you get the Slingshot or Bow and arrow, look for Malo. He is the child that resembles a little infant. Pull out either of these objects and stand in front of him. Shoot him with it. He will pull his head back and say nothing. Alternately, when you defeat the Darbus from Death Mountain go back into Kakariko Village and find Malo. He is up on one of the higher ledges scouting the area for monsters. He will ask if you can show him how to use a bow. Say yes and you will be brought down next to Malo for instructions. Turn your camera but do not move yourself and look at Malo. His eyes will make him look like a child from a horror movie.
