It was a successor to the Jack Stone theme and used regular LEGO bricks but came with a different kind of minifigure that was larger then the standard minifigures. The sets tended to have a small number of larger pieces, in order to be easy to put together. The 4 Juniors theme consisted of Pirates, City and Spider-Man subthemes.
