Mole Bridge

Mole Bridge

• Once upon a time, you lived in a town by the name
  of Given. You had some friends who lived in the
  nearby town of Askedfor. One day you decided to
  visit your friends in Askedfor, but the only way
  to get from Given to Askedfor is to cross Old
  Mole Bridge. The reason they call it Old Mole
  Bridge is that only moles are allowed to cross.
  So the only way to get to Askedfor is to change
  yourself into a mole and cross the bridge. Now,
  you dont want to be a mole any longer than you
  have to, so after crossing the bridge, you change
  yourself back, and youve made it to Askedfor.
