The Hedge Maze
The Hedge Maze is east of the Mansion, past the Greenhouse.
Enter the Maze and turn around. A wall of leaves takes the space where the entrance was. Find the center of the Maze. If an animal crosses your path (a doe, a frog, a lamb, a wumpus), stay still until it passes. If a whirlwind crosses your path, walk past it or else it will carry you back to where you started.
Yet another gazebo stands at the center of the Maze. Standing amidst the columns will make the hedges unfold into topiaries. The topiaries will shift and arrange themselves, revealing an exit out of the Maze.
