The Balinese use every part of the coconut tree. The husks are used for coir mats and ropes, the inner layer is used for buttons and a lot fish gets grilled over the husks. The leaves are woven into hats, baskets, offerings, temple decorations and ketupot which are woven shapes used to cook rice. The meat and milk are used in many Balinese foods and cosmetics. They even use the roots as a medicine.
These coconuts look more like giant green olives...
