Youngsters love the amazing Hidden Side universe, where the physical and digital worlds merge. This LEGO Hidden Side Supernatural Race Car 70434 playset combines a buildable model with an app for a single or multiplayer, mixed-reality play experience, where interaction with the toy triggers events in the digital world. The Supernatural Race Car reveals the haunted Hidden Side when viewed through a smartphone or tablet equipped with the LEGO Hidden Side AR app. Kids can then explore, solve mysteries, hunt ghosts and battle boss ghost Maxine Turbo in an action-packed digital world. Kids can also switch the wheels of the car from driving to flying mode and enjoy hands-on adventures with the Jack, Vaughn and Shadow-Walker minifigures and a Spencer the dog figure. LEGO Hidden Side toys bring interactive augmented reality (AR) play to LEGO models. The play experience is constantly enhanced through new content, ghosts and special events.
