Moon Cup

The Moon Cup is a cup that appears in Mario Kart 8 Deluxe as part of the Booster Course Pass DLC. It is the second of two cups in the third wave of the DLC, being released alongside the Rock Cup, the sixth cup of the pass overall, and the eighteenth cup of the game overall. Like most cups in the pass, it only features classic courses. Excluding the Extra Cups in Mario Kart: Super Circuit and the cups in Mario Kart Tour, this is the second cup in the Mario Kart series to feature two classic courses from the same game, after the Lucky Cat Cup, as it features two courses from Mario Kart Tour: Berlin Byways and Merry Mountain. The emblem of the cup is a Power Moon.

Additionally, a video uploaded by Nintendo of America on YouTube lists  as the second course of the cup.
