In Aliya's Baby Sister's Playroom, everything revolves around caring for baby Amalia. This Heartlake City set introduces clever interactive elements, such as a dining table with a flip function that comically reveals a "mess" during mealtime. Includes mini-dolls of Aliya and Liann.
With 125 pieces, fans build a compact playroom equipped with a slide, ball pit, baby swing, and stroller. The late 2024 release is packed with small details, including a cute plush duck and various baby bottles.
RRP €22.99. A fun and accessible expansion for a modern Heartlake City layout, ideal for anyone looking to incorporate daily family life in LEGO form.
