How does the fox imply the creative response of the speaker?

After reading and analyzing "The Thought-Fox," it's easy to see why the image of a fox emerging from the edge of a dark forest is similar to an idea developing and surfacing from the depths of a writer's mind. The fox's manner—sneaky, clever, bold— echoes the way which an inspiration can suddenly strike, while the forest's setting—dark, dense, deep—is much like a writer's imagination.
