- Talking to Himself:
- What Could Have Been:
- The Komodo Bros, Rilla Roo and Nina Cortex were all originally intended to be playable characters, but were scrapped for unknown reasons. In the latter's case, it would have been her second Early-Bird Cameo before her official debut in Twinsanity.
- Velo and the other bosses have unused voice clips suggesting they were originally intended to be playable in the console versions as well. The Velo Mask also has unused dialogue that implies it was originally intended to speak like Aku Aku and Uka Uka do.
- Data of a "Virtual Lobby" exists within the game's files in a fairly comprehensive state, implying it had a lot of work done before it ultimately got cut. Apparently, it would have allowed players to race or battle each other online in an early form of online multiplayer, predating Mario Kart Wii and its online multiplayer by almost half a decade.
- Early trailers and data mines imply the game would have been larger, with 17 race tracks and at least 2 more battle arenas, essentially making it the same size as CTR. Yellow token/gem data also exists inside the final game, implying tracks were going to be made to correspond to the missing colour cup.
