The Great Outer Maze

The Great Outer Maze is a legendary maze that is avoided by Fraggles at all costs. It is said that Fraggles can get lost in the maze; and there is also an Invisible Garboil. The Garboil isn't actually invisible, it is seen as as mist with great winds that terrorizes the Fraggles. When Gobo accidently frees the Garboil, he takes it upon himself to capture the Garboil. He does this by using Wembly's siren to attract the Garboil.
