"Toy Story 2" is the exciting, all-new sequel to the landmark 1995 computer-animated blockbuster from Walt Disney Pictures and Pixar Animation Studios.  This time around, the fun and adventure continue when Andy goes off to summer camp and the toys are left to their own devices.  Things shift into high gear when an obsessive toy collector kidnaps Woody -- who hasn't the slightest clue that he is a greatly valued collectible. It's now up to Buzz Lightyear and the gang from Andy's room -- Mr. Potato Head, Slinky Dog, Rex, and Hamm -- to spring into action and save their pal from winding up a museum piece.  There are plenty of thrills as the toys get into one predicament after another in their daring race to get home before Andy does.
