Your shaking has loosened the log from the earth that was holding it in
place.  The log shakes as it begins to free itself, beginning to roll slowly
carrying you over and over again.  The spin begins to get faster and you
feel the log leave the ground returning to the earth with a thud.  The log
cracks a little as it smashes it's way over a large rock.
