Three new trees will be added into Minecraft PE by this addon, and they are much better than regular. First of all, the new trees have branches, and they are growing pretty random. Another important thing - the trees have an appropriate animation of falling. When you chop the tree, its trunk will start to slowly fall to the ground, and only when it's done - you'll get all wood at once. The trees also will be spawning automatically, but you can spawn them manually from the Creative inventory at any time.

From the palm tree, you can get a Coconut. Put a Coconut into a Crafting table and create a refreshing drink that will restore your health.
