In Sydney, Australia, Gadget explores the Hyde Park Barracks, visits the first European colony at The Rocks, and steps aboard the Solaway Lass. // Gadget escapes to Alcatraz to find out how three resourceful prisoners broke out of this former island prison, and he visits the cells of Al Capone and Machine Gun Kelly. Next he stops off at Ghiradelli Square to explore the art of chocolate-making, then takes off to the California Academy of Sciences where he's shaken up by a simulated earthquake.
