An exploit for the Switch 2 discovered earlier this month has allowed dataminers to inspect game files for Switch 2 exclusives, including Mario Kart World.
The findings, shared publicly by YouTuber Rimea and attributed to researcher mondomega on BlueSky, include references to multiple driver entries that are not currently playable in the published game.
According to the reports, dataminers located references to nine driver entries in files associated with character attributes.
The entries listed are Thwomp, Blooper, Ninji, Goomba Twins, Chain Chomp, Fuzzy, Bird, Banana and Spiny.
Rimea relayed that mondomega identified eight additional potential drivers in a file tied to character weight statistics, specifically naming Twomp, Blooper, Ninji, Goomba “twins,” Chain Chomp, Fuzzy, “Bird” and “Banana.” The tweet reporting the find was posted on October 28, 2026.
Rewriting that account into journalistic language: Rimea reported that mondomega uncovered a set of character-weight entries inside Mario Kart World’s data files, and those entries include several familiar Mario enemies and item-based placeholders that do not correspond to playable characters in the retail release.
These discoveries are limited to file references and internal data; Nintendo has not issued an official statement confirming the nature or intent of the entries.
The status of these assets — whether unused, placeholders, or intended for a different build — has not been confirmed by the developer.
As with other instances of datamining, the presence of strings, identifiers or asset names in game files does not by itself demonstrate planned or cancelled content.
Context: Mario Kart World follows a long-running franchise developed by Nintendo (including Nintendo EPD on prior installments).
The Mario Kart series has a history on Nintendo platforms, with Mario Kart 8 Deluxe releasing for Nintendo Switch in April 2017 and becoming a major title for the platform.
For official updates about Mario Kart World, players should monitor Nintendo Direct presentations and the Nintendo eShop listings.
This report compiles verified findings from public posts by Rimea and mondomega.
Nintendo or the game’s developers have not provided additional confirmation; further technical or official details may emerge if Nintendo chooses to comment or publish updates.
