Tree

Trees seem to be an important symbol in Zisteau Plays Minecraft.

Chapter One/Two
A lone tree provides the key to survival on Survival Island and Sea of Flame.

Chapter Three
In Chapter 3, trees play a much bigger role. A leaf tunnel appears in the forest Zisteau ends up planting near the end of the chapter, leading the way to CanopyCarnage and the key to escaping the Kaizo Caverns.

Chapter Four
The tree on the Skyblock island retains the wood type gathered in the previous playthrough. Also, the glimpse of the Skyblock world shown in Enumerator shows Zisteau walking past a tree. Eventually the tree becomes the center of Zisteau's base, and there is also a leaf tunnel but it is a red herring.
