On August 29, 2025, Nintendo updated the Japanese website to include new stickers, some of which feature emblems for the game's courses. While the stickers clearly correspond to known tracks, such as Crown City and DK Spaceport, some of the file names for the stickers reveal potentially cut content. The most notable examples include Moo Moo Meadows (Moo Moo Farm from Mario Kart 64), Faraway Oasis (DK Jungle Parkway from Mario Kart 64), and Starview Peak (Rosalina's Ice World from Mario Kart 7).
