About LEGO Explore

The LEGO Explore theme was designed by the LEGO Group with collaboration with experts in child development creating sets designed for discovery using LEGO DUPLO elements to help parents understand the various development steps toddlers go through and what type of play would benefit this development. Explore was released in 2002 and introduced four universes each supporting a certain step in children’s development: Explore Being Me – Discovering who I am and what I can do, Explore Together – Learning to share and interact with others, Explore Imagination – Expressing my personality and creativity and Explore Logic – Understanding how things work.
2003 LEGO Sets
In 2003, LEGO faced one of its most challenging financial years, but it also introduced several innovations that would shape the company’s future recovery. The most notable change was the introduction of realistic minifigure skin tones for licensed themes, including Star Wars, Harry Potter, Spider-Man, Ferrari, and Basketball. While classic yellow remained the standard for non-licensed minifigures, this shift helped distinguish characters based on real-world figures and franchises, marking a major evolution in LEGO design.
