Hidden Side Sets

Hidden Side™ invites kids to join a fearless team of ghost hunters, who dare see the unseen and help turn a haunted world back to normal, one ghost at a time. This new theme includes a series of “haunted” building sets full of awesome functionality and secret surprises that, on their own, provide the build and roleplay fun of any LEGO® theme. Activating the free augmented reality app brings the models to life, revealing a hidden world of interactive mysteries and challenges to solve. When combined, the two worlds make each other even more compelling and fun. The app also consists of a digital game that kids can play independent of the building set.
