Luigi is joining Lego’s interactive Mario sets A palette swap for Luigi lovers Share this story Luigi — everyone’s favorite also-ran brother of the most famous mushroom-stomping plumber — is joining Lego’s interactive Super Mario collection of sets in a new starter kit (creatively titled the LEGO Super Mario Adventures with Luigi Starter Course.) The new Luigi figure is technologically similar to the Mario one, with a built-in display that animates his eyes, mouth, and a main screen on his chest and a sensor on the bottom that’s used to scan barcodes and brick colors. The main differences are cosmetic here — Luigi looks different, and features different sound effects, voice lines, and character interactions.
