"A piece of coconut"
Two coconut halves can be acquired by smashing a drinkable coconut with the drag mechanic (RMB by default) or by bisecting it with any sharp tool, such as a pocket knife. When breaking it with a sharp tool, it must be hit it 7 times to obtain the halves.
Coconut halves serve as a starter food item for newer players, or as an emergency consumable for when traveling. Once consumed, a pair of coconut halves restores one hunger unit on the player's hunger meter.
While the player is capable of carrying four coconut halves per inventory slot, it is more efficient to carry several whole coconuts instead - each coconut consists of two halves, and the player is capable of stacking four coconuts per inventory slot (an equivalent of eight halves per slot, or a total of thirty-two halves maximum). Storing whole coconuts also gives the player the benefit of carrying coconut fluids in case of emergency. However, the player will still need a sharp tool to break the coconuts open.
