LEGO Super Mario Builder Mario Power-Up Pack 71373 – Building Kit for Kids

Overview

Elevate LEGO Mario’s adventures with the Builder Mario Power-Up Pack (71373). This 10-piece set adds a buildable, interactive outfit that can be worn by LEGO Mario to unlock new in-game possibilities as players stomp across custom courses. The moment-to-moment action—colors snapping together, bricks clicking underfoot, and the figure moving in a new disguise—brings a tactile layer to play that many kids find exciting and immersive.

The outfit is designed to fit the LEGO Mario figure included with the Adventures with Mario Starter Course (71360). Note that the 71373 pack does not include the Mario figure itself, so it works best when paired with an existing figure from the Starter Course. For help with building and ideas, the free LEGO Super Mario app offers illustrated instructions, inspiration, and a safe space for kids to share their creations with friends and family.

What you get and how it works

• 10-piece buildable costume that attaches to LEGO Mario to unlock new gameplay options
• A scalable way to expand the Adventures with Mario Starter Course and related Expansion Sets

When LEGO Mario (figure not included) wears this outfit, players can earn digital coins by making him stomp on the bricks of their self-built courses. This simple mechanic adds a goal-oriented twist to play, encouraging experimentation with level design and timing.

Real-life use cases and play scenarios

• Kids can design compact courses at home that center on stomping maneuvers and coin collection, then trade ideas with friends or family for friendly competitions
• The modular nature of LEGO Mario upgrades allows for quick reconfigurations, helping kids explore different layouts, challenges, and storytelling ideas

Beyond this Power-Up Pack, LEGO offers additional upgrades such as Fire Mario (71370), Propeller (71371), and Cat Mario (71372) packs. These can be mixed with the Starter Course and Expansion Sets to create varied scenarios, another way to keep play fresh without buying a whole new setup.

The LEGO Super Mario app complements the physical kit with illustrated building instructions, inspiration, and a safe space for kids to share their creations. This combination of hands-on building and digital guidance supports curiosity, problem-solving, and imaginative play in a kid-friendly environment.

Gift-ready and kid-friendly

Designed as a thoughtful addition for fans of the Adventures with Mario Starter Course, this Power-Up Pack makes a charming gift for birthdays or holidays. It invites kids to imagine, build, and test new ideas, while staying within the familiar LEGO Mario universe—and it can be enjoyed solo or with friends.
