Description

An add-on, not a starter set

This set only makes sense once you already own an interactive Mario or Luigi figure, since it has no play function of its own. Instead, it plugs into an existing course and opens up a new area to explore. At 179 pieces the build stays short, which suits it well as a between-projects add-on rather than a weekend project. Collectors expanding an existing layout get the most out of it, because each expansion set contributes its own mechanics and scenery.

Straight from the games

The design nods to the Luigi's Mansion video games, where Luigi hunts ghosts through a haunted house using an oversized vacuum called the Poltergust. Here that vacuum becomes a display piece next to a small lab where it is presumably serviced between hunts. There are no minifigures, since the scene is built to interact with the Mario or Luigi figure from the main range rather than to be played with on its own. Players familiar with the games will spot several nods to the source material.

A restrained colour palette

Of the 179 pieces, 110 are unique parts, a fairly high ratio for a set this size and a sign of varied shaping rather than repeated basics. Colours lean subdued: light bluish grey and dark bluish grey for structure, black for detailing, and a bright light orange accent that likely marks the Poltergust itself. That combination reads calmer than many Mario sets and suits a slightly spooky, mansion-style setting better than the usual bright palette. The full parts list with every colour is further down this page.

Who it's for

71397 suits anyone building out a LEGO Super Mario course who wants a Nintendo horror theme alongside the usual platforming courses. It is not worth buying without a base figure already in hand, but as an addition to one it fills a specific gap. The build stays short at 179 pieces, so it also works as a quick project alongside a larger set. Fans of the games get a display piece that stands up on its own once the interactive play is done.

FAQ
