In the beginning of the game, when FLUDD is scanning Mario, there are videos playing in the bottom-left corner of the screen. These videos are Mario fighting Bowser in "Super Mario Bros", Iggy Koopa in "Super Mario World", and Bowser again in "Super Mario 64." In the opposite corner is a list of backwards names which represent past Mario games. Looking closely reveals that both Super Mario Kart and Mario Kart 64 were written with the word KIRT instead of KART.
