Coconut

A coconut is a seed whose internal contents is consumed primarily by humans. It grows on plants; particularly palm trees, indigenous to Earth. Botanically, a coconut is a simple dry nut known as a fibrous drupe. The husk, or mesocarp, is composed of fibers called coir and there is an inner stone, or endocarp. This hard endocarp, the outside of the coconut as sold in the shops of non-tropical countries, has three germination pores that are clearly visible on the outside surface once the husk is removed. It is through one of these that the radicle emerges when the embryo germinates. Adhering to the inside wall of the endocarp is the testa, with a thick albuminous endosperm (the coconut "meat"), the white and fleshy edible part of the seed.

It can be found on the Halo 2 levels Zanzibar and Ivory Tower, atop palm trees. They can be shot out of trees (weaker weapons so that the fruit doesn't get destroyed) and played with.
