LEGO Duplo Supplementary sets are additional sets of bricks and pieces designed to complement existing LEGO Duplo sets. These sets often include specialized pieces like windows, doors, and unique characters or accessories, expanding the creative possibilities for young builders and encouraging imaginative play.
The LEGO DUPLO theme is designed for children ages 1 to 5. It features DUPLO figures which are much larger than minifigures and DUPLO blocks which are about twice the length, width, and height of a standard System brick.
