Investigate the phenomena in Newbury with the LEGO Hidden Side Mystery Castle (70437-1) set, comprising 1035 pieces. This digitally interactive ghost-hunting toy combines a physical castle model with an augmented reality (AR) app experience, bringing the structure to life. The castle model folds out, utilizing hinge plates for its transformation, setting the stage for role play with Jack, Parker, Vaughn, Nehmaar Reem, and two Shadow-Walker minifigures. When viewed through a smart device, the AR app allows explorers to delve into a digital world, solve mysteries, hunt ghosts, and confront boss ghost The Maw. The set continually evolves with new digital content and characters, enhancing the ongoing adventures within the castle walls.
