This set uses the box itself as part of the play construct. The theme is of a LEGO factory employee inspecting minifigures that roll off the assembly line, celebrating the 40th birthday of the first introduction of Minifigures. The set includes a minifigure and 5 microfigures. The microfigures include the original police officer from 1978, a LEGO Pirates figure with a striped shirt, a blue Classic Space fig, a Ninjago character called Pixel Rebooted, and a doctor from LEGO City. This set was a free promotion item in LEGO stores and LEGO.com online with qualified purchases. The set is to celebrate the 40th anniversary of the LEGO minifigure.
