Coconuts here are used before they are ripe (brown).  Buko is what you call a green coconut,  They're used to make dessert salads, drinks and ice cream specialties.  The inside of the coconut is shredded to be used in salads and the juice is sold on the street as a refreshing drink. We took this picture just outside of the Elders' apartment,

This is shredded coconut in buko juice.
