Once there was a magical park where kids of all ages could run the Serengeti with the Great Beasts, ride the haunted rails of a Wild-West Ghost Train, explore Lost Atlantis, shrink to the size of a Hard Candy, and journey to the heart of a Black Hole... All in a single, magical day! But then there was an accident, and the doors to Adventure Park slammed shut forever. Now, three friends must embark on a daring adventure of their own: returning to the long- abandoned fantasy park to save their missing friend.
