Bright and playful. — “A lovely set - truly. It is definitely my favorite of the Duplo Disney Princess Range. Expensive, yes...hence my expectation of well designed components, all but the treasure chest. This is a good set to start younger children on as the large turrets and accessories add... More interest.”

“This LEGO Duplo Little Mermaid set includes Ariel and Flounder figures, a slide, a swing, a treasure chest, and detailed bricks like a Sebastian decoration, offering plenty of creative possibilities. While assembly might need some parental help, the set's movable Ariel figure and fun accessories ensure hours of imaginative play.”
