J.B's Ghost Lab

The LEGO® J.B's Ghost Lab (set 70418) is a 175-piece LEGO Hidden Side set released in 2019, an augmented reality playset where building meets a companion smartphone app. The mad-scientist lab features tech details, scientific equipment, and a pop-up panel with an alarm message that ghost-hunters can interact with through the Hidden Side app. Includes three minifigures — Jack Davids, J.B., and Douglas Elton — plus the cute ghost dog Spencer. Pointing a phone at the model reveals an ever-changing haunted environment, blending physical bricks with digital ghost-hunting adventures.
