The aliens have arrived, and in spite of all their advanced technology,
they're feeling a little lost. Have some 3-D fun while you guide them
around our big blue planet. Put on the enclosed 3-D glasses and watch
these brilliantly colored labyrinths pop right off the page. Some of the
mazes offer twice the excitement with double-paged spreads. And don't
worry--complete solutions guarantee that you'll be able to find your way
before the visitors get impatient and vaporize you.
