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.”
