LEGO Super Mario Diddy Kong's Mine Cart Ride Expansion Set 71425 – 1,157-Piece Gift for Kids 8–10

Expand Your LEGO Super Mario World

The LEGO Super Mario Diddy Kong's Mine Cart Ride Expansion Set 71425 invites kids to push the action beyond the starter course with brick-built adventure inspired by Donkey Kong. With 1,157 bricks and a colorful cast, this expansion adds motion, surprises, and story moments to play sessions.

Designed for kids ages 8–10, this set blends physical building with digital play via the LEGO Super Mario app. When combined with a compatible Starter Course, it unlocks interactive play that can be rearranged into new levels over time.

What’s included and what you can build

• 1,157 bricks to construct a detailed mine cart ride, rock section, and banana reveal.
• 4 figures inspired by the Donkey Kong world: Funky Kong, Diddy Kong, Snaggles, and Mole Miner.
• A buildable Funky Kong airplane/shop featuring two Action Tags for interactive reactions—one for balloons, one for flight.
• A set of interactive mechanisms to flip obstacles, advance the cart, and trigger playful reactions during play.
• Clear instructions and a design that invites mixing with other LEGO Super Mario sets to form custom levels.

How play happens and why it’s engaging

• Kids can ride the mine cart using LEGO Mario, LEGO Luigi, or LEGO Peach figures (not included) to simulate on-track action and turning challenges.
• The rock section can be “exploded” to reveal a bunch of bananas, creating a playful reward moment within the story.
• Initiating balloon purchases and plane flight with the Funky Kong airplane adds a light, flight-themed layer of play that complements track-based action.
• As a collectible gift, this set invites ongoing exploration: rearranging bricks, swapping figures, and building new routes with other LEGO Super Mario kits.

Compatibility, app, and gifting ideas

The expansion requires a compatible Starter Course (71360, 71387, or 71403) for interactive play. The LEGO Super Mario app offers building instructions and inspiration to expand creativity, track potential, and story options. It also helps younger builders follow along as they assemble the model.

Whether you’re shopping for a birthday or holiday surprise, this 1,157-piece set offers a satisfying, tactile build and a world where fans can imagine new Donkey Kong–themed challenges. It’s designed to fit into a broader LEGO Super Mario collection, enabling kids and fans to craft their own levels before or after screen time.
