Sky-High Sundae

Sky-High Sundae is a course set to be released as part of Wave 2 in the Booster Course Pass for Mario Kart 8 Deluxe and at a later date in Mario Kart Tour. This essentially makes Sky-High Sundae the first course from Mario Kart 8 Deluxe to make an appearance before Mario Kart Tour. It is the fourth and final course of the Propeller Cup in Mario Kart 8 Deluxe and the only new course in the Booster Course Pass. It is set in a large region made entirely of ice cream and other candy-related food high in the sky. It is the fourth course in the series to be set entirely in anti-gravity, after Mute City,, and Big Blue.
