Koa Wood

 Koa Wood is a large variant of wood found exclusively in the Tropics Biome. It can take up to about 40 chops with a Rukiryaxe to completely slice large portions of this tree, due to it being one of the thickest in the game.

 The Koa Tree is very similar to an Elm Tree, but slightly smaller in size. The log is a light-brown shade, while the interior is a reddish-brown; but it still remains brighter than Walnut Wood.

The tree's leaves are massive, and since the actual structure of the trees is not that tall, the leaves cover most of the wood, making these trees look like giant bushes. In fact, when driving under Koa trees, you have a chance of hitting the branch as the leaves are so massive they conceal them. The leaves have two different shades of green. Koa logs are some of the most expensive logs in the game, but the price of the tree's planks are a bit lower than that of Lava Wood planks.

To obtain this type of wood, you must ride the Ferry by paying Hoover $400 money, thus taking you to the Tropics Biome. Once there, the player must chop down any desired amount of wood and ride back to the mainland for milling or selling.
