The Maze of the Root
This maze is located by entering the Green Button Door, and being a friend of nature. (Planting all 8 different seeds.)
When you enter through the door that is sealed by magic, you will enter into a room filled with Tall Anthonys in flower plots. Passed this area is the door that leads to the Maze of the Root.
This is no ordinary maze, as inside of it, has an extreme amount of doors that teleport you to another door in the maze when you have walked through one. The exit is currently unknown and in the process of locating.
