Jack Stone is a theme that was introduced in 2001 and discontinued in 2003. The most noteable feature of the theme was its larger, more detailed minifgures. The sets have a strong civic action theme, with Jack Stone himself acting in various roles such as a Policeman, Fireman, Worker, Coast Guard, and Pilot. The theme was replaced by 4 Plus, which retained the adapted minifigures, but considerably reduced the focus on Jack.
