About LEGO Friends

LEGO Friends sets are designed to appeal to girls and were introduced in 2012. The Friends theme includes mini-doll figures, which are around the same size as minifigures but are more realistic. LEGO Friends pieces are fully compatible with all LEGO System bricks and sets include pieces in pink and purple color schemes and depict scenes from suburban life set in the fictional town of Heartlake City.
