The datamine, which was shared on social media by user Rimea and first flagged by MondoMega, appears in files related to character weight statistics and contains several familiar Mario-series enemy names.
The entries identified in the weight-stats file include a mix of classic enemies and series oddities.
The full list reported from the datamine is:
- “Bird” and “Banana"
- Blooper
- Chain Chomp
- Fuzzy
- Goomba “twins” (likely a Goomba Tower-style entry)
- Ninji
- Spiny (listed under the Japanese name Togezo in some files)
- Thwomp
Journalistic summary of the reporting: social posts indicate these driver names exist in internal Mario Kart World data files tied to character attributes, but they are not present in the game’s playable roster.
Observers noted that while fake datamines have circulated around Mario Kart World in recent weeks, the files in this instance have been treated by some analysts as legitimate and consistent with internal naming conventions.
Nintendo has previously limited non-Mario cast members in certain Mario Kart releases.
Producer Kosuke Yabuki has addressed character-selection decisions for the series in past communications; in line with prior developer commentary, Mario Kart World’s final roster reflects the team’s curatorial choices for the release.
Mario Kart World is available on Nintendo Switch 2.
The game launched with one of the largest rosters in the Mario Kart series, according to published coverage of the release.
Datamining remains a frequent source of community discoveries about unused assets and cut content, but readers should continue to treat such findings cautiously until official confirmation from Nintendo.
This datamine adds to ongoing interest in Mario Kart World’s development files and raises fresh questions about characters considered during production.
Readers familiar with the series may recognize many of the names above as longstanding Mario enemies and recurring franchise elements.
