Kokiri Trees, Wood, Planks and Sticks

In the mod there's a Kokiri Tree included. It has it's own sapling, logs, leaf block and, subsequently, has planks and the Kokiri Stick.

The Kokiri Trees aren't generated in the world yet, however, the saplings do have a chance to spawn in Jungle Temples. The saplings will grow as normal, either by leaving them for long enough for by using a single bonemeal on them.

The Leaf Blocks have a small chance of dropping Force Gems.

When I get world gen properly sorted out, these trees will be properly added to the world.

Wood, Planks and Stick
The wood of the Kokiri Tree is made from Kokiri Logs. These can be crafted down into Kokiri Planks, which can then be crafted down into Kokiri Sticks. Kokiri Sticks are used quite a bit in crafting.

As with any other Log block, if you put the Kokiri Log Block anywhere into the crafting table you'll get 4 Kokiri Planks Blocks out of it.

You make Kokiri Sticks in the same way you make Vanilla Sticks, you simply put 2 x Kokiri Planks Blocks, one in the slot above the other, into the crafting table. You'll get 4 Kokiri Sticks out of this.

Known Bugs
Sometimes the bottom most Kokiri Wood Block will face sideways when you bonemeal the sapling.
