LEGO Super Mario 71390 Reznor Knockdown Expansion Set

LEGO 71390, Reznor Knockdown Expansion Set, is a Super Mario set released in 2021.

Set 71390 brings a Reznor focused challenge into the LEGO Super Mario theme. As an expansion set, it is best understood as an added course section rather than a self contained display scene. Its subject connects directly with the game based structure of the theme, where built obstacles and enemies define the play route.

The model uses 862 pieces to form a course environment with interactive play potential. For that reason, the contents are better described in terms of scenery, obstacles and functions, not as a character pack.

This set suits builders who already follow LEGO Super Mario and want a more varied layout. It can also work in a collection as a distinct Reznor themed module. Within the theme, it belongs with the expansion sets that extend the course system through additional challenges, constructed terrain and recognizable moments from the Mario universe.
