LEGO Friends Mini-doll figures are a distinct type of figure introduced in 2012 as part of the LEGO Friends theme, designed to appeal primarily to girls. These mini-dolls are more detailed and realistic in proportions compared to traditional LEGO minifigures, featuring movable limbs, interchangeable hairpieces, and a variety of accessories. They are slightly taller and slimmer, with a more lifelike appearance that enhances the play experience by providing a closer representation of human characters.

The LEGO Friends theme centers around the lives and adventures of five main characters—Andrea, Emma, Mia, Olivia, and Stephanie—in the fictional town of Heartlake City. Each character has distinct personalities, interests, and hobbies, reflected in the diverse sets that include houses, shops, vehicles, and various community locations.
