LEGO Super Mario Boomer Bill Barrage Expansion Set 71366 — 132 Pieces

Boost your LEGO Super Mario Adventures with the Boomer Bill Barrage Expansion

Transform your brick-by-brick universe with the Boomer Bill Barrage Expansion Set (71366). This 132-piece add-on introduces a fast-spinning challenge, a rotating platform, two airborne Boomer Bill figures, a Shy Guy foe, and a Super Mushroom power-up to spark fresh gameplay options for your Super Mario world. The set is designed to integrate with the Starter Course (71360) and other expansions, inviting creative level-building and playful competition with friends or family.

The centerpiece is a spinner-driven platform that lets LEGO Mario (figure not included) navigate a dynamic course. Depending on placement, the same layout can offer different pacing and difficulty, encouraging experimentation with timing, precision, and strategy. The included Shy Guy and the Super Mushroom add familiar elements from the Mario universe, expanding the scene without overwhelming the build.

As you assemble, you’ll notice the tactile joy of turning parts, clicking studs, and seeing how the pieces fit into a broader LEGO Super Mario playground. The construction also serves as a stepping stone for more ambitious level design, whether you’re stacking this expansion with the Starter Course or mixing in other Expansion Sets to create larger, more challenging adventures.
