LEGO 4 Junior Value Packs, also called Bonus Packs, are bundles that contain several LEGO sets in one offer. Typically, these contained sets are not available in retail with the main selling points of Value Packs is the inclusion of an exclusive model and a lower price when compared to individual purchases of the same sets.
4 Juniors, also known as 4 Plus was a theme introduced in 2003 by LEGO that targeted children of four years old or more. 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.
