Description

Another add-on for the track

Boomer Bill Barrage follows the same pattern as other LEGO® Super Mario expansion sets: it needs a starter course with an interactive Mario, Luigi or Peach figure to be playable, rather than working as a stand-alone toy. The centrepiece is an oversized Boomer Bill, a cannon-fired enemy from the Mario games, built here as a fixed obstacle. At 132 pieces, it's a typical size for this line of expansions, quick enough to build in one sitting before adding it to a larger course.

A high ratio of unique parts

With 70 unique parts out of 132 pieces total, this set stands out for how varied its part count is – roughly every second piece is a distinct element type. That points to a build with a lot of small, specific detail pieces shaping the character, rather than large repeated sections. Medium nougat likely covers facial or joint details, while black forms the bulk of the Boomer Bill's body, and that combination of colours carries through most of the model.

Red and grey for contrast

Red is used for small accent or warning-style details, while light bluish grey forms the base of the track structure itself. Set against the black of the Boomer Bill, that combination keeps the obstacle visually distinct from the surrounding grey track, which matters during actual play with an interactive figure – the obstacle needs to read clearly at a glance rather than blend into the rest of the course when several sections are connected.

Comparing part types across expansions

The 70 unique parts listed on this page make it straightforward to see exactly which shaped pieces went into the Boomer Bill, useful for anyone who owns several Super Mario expansion sets and wants to compare them directly. It also helps in judging which specialised pieces might be worth keeping aside for track modifications or custom layouts, particularly the grey track pieces that tend to reappear across the wider Super Mario range.
