LEGO Super Mario Donkey Kong's Tree House Expansion Set - Playful

Our review of the LEGO Super Mario Donkey Kong's Tree House Expansion Set finds it best suited for kids aged 8 and up and collectors who want a colorful, interactive Donkey Kong level. The single biggest reason to buy is the set's characterful, modular play design: with 2 collectible figures, a buildable tree house full of authentic details and elements that interact with existing LEGO Super Mario starter figures, this 555-piece set converts into a lively jungle scene that rewards imaginative role play and creative rebuilding.

Key Features

• Collectible figures: Includes Donkey Kong and Cranky Kong so fans get iconic characters to stage scenes and challenges without hunting separately for figures.
• Interactive play: The buildable tree house has a hammock, TV, radio and secret compartment to spark storytelling and varied play actions.
• Starter set compatibility: Works with LEGO Super Mario starter courses so children can ride on Donkey Kong's back with LEGO Mario, Luigi or Peach for connected play.
• Modular design: Measures over 7.5 in high and 18 in wide in basic form and can be rebuilt or combined with other sets for expanded levels.
• Physical rewards: Actions like knocking a banana off the palm tree or visiting Cranky Kong translate into in-game reward opportunities when paired with a starter figure.
• Digital support: Downloadable building instructions via the LEGO Super Mario app help with assembly and offer inspiration for larger builds.

Who It's For

This set is ideal for kids aged 8 and up who already own or plan to own a LEGO Super Mario starter course and who enjoy hands-on, story-driven play. It also appeals to Super Mario and Donkey Kong fans who like displayable, character-rich builds that can be rearranged into new levels.

Families looking for a self-contained toy that works without additional purchases should look elsewhere, because interactive features require a separate LEGO Super Mario starter figure to unlock the full digital reward experience. Builders who want very large standalone landscapes may prefer bigger modular expansion packs to create longer courses.

Pros & Cons

Pros
