Nintendo is rolling out a time-limited Super Mario Bros. crossover for Donkey Kong Bananza’s DLC, offering players the chance to dress Donkey Kong and Pauline in Mario and Luigi-themed costumes during specific event windows.
The crossover was highlighted alongside other announcements during the June 2026 Nintendo Direct coverage.
What to expect
Owners of Donkey Kong Bananza’s DLC packs — DK Island and Emerald Rush — will be able to equip Mario and Luigi costumes for Donkey Kong and Pauline respectively, but only during designated time slots.
Nintendo has not confirmed whether these costumes will become permanent unlocks or remain accessible only while the event waves are active.
The publisher also did not list any additional challenges or new content tied to the costume drops.
Event schedule
The crossover will be available in four separate waves:
- June 9, 2026 – June 30, 2026
- July 14, 2026 – July 21, 2026
- August 4, 2026 – August 11, 2026
- August 25, 2026 – September 1, 2026
The windows make the crossover a strictly time-limited celebration tied to the Super Mario Bros. 40th anniversary festivities that have appeared across Nintendo’s summer showcase.
Coverage and context
Journalist Peter Glagowski noted the incongruity of marking a once-in-a-lifetime anniversary with ephemeral in-game content, observing that a time-limited event emphasizes the temporary nature of the celebration.
This crossover was one of several items mentioned during June 2026 coverage: Final Fantasy Resonance is scheduled to launch on October 22, 2026, Splatoon Raiders received a Direct Presentation slated for June 30, and DK Challenge was described as a limited-time, Nintendo Switch Online exclusive event for Switch 2 owners.
How to participate
Players who own the relevant Donkey Kong Bananza DLC should launch the DLC during any of the listed windows to access the crossover costumes.
As with other time-limited events promoted during Nintendo Direct presentations, availability is tied to the published schedule and the game’s DLC ownership status.
This announcement adds another seasonal crossover to Nintendo’s catalog of time-limited in-game events on Nintendo Switch platforms.
