  You are inside the Mad Mole.  You stare in disbelief as you stare into
the light of technology.  From head to paw, the Mad Mole is made of iron. 
You stumble as the Mad Mole furiously races through the crust.  You can't
see outside, but by the feeling you get, you know you are going fast.  In
the center of the mole are seats, each with rope attached to them for tying
around your waist, to prevent the passenger from flying into the wall.  On
the inside of the head you see an inscription reading "M-A-D."  You sweat as
you feel the temperature rise and the air grow thinner.
