While walking along Bob suddenly realized that the walls surrounding them weren't that tall and he had definitely had plenty of times where he had needed to quickly infiltrate castles or fortifications with relatively low walls.  He could climb up to the top of the walls to get a better view of the maze and perhaps discover the whereabouts of the voices he continued to hear.<br/><br/>"My friend if you will excuse me for a moment, I believe I may be able to gain us an advantage, however small.  I shall return shortly."<br/><br/>With that he started using his fists and feet to make small enough indents in the wall to use as footholds, and he did it with amazing speed.
