Mario Kart 8 Deluxe’s Booster Course Pass costs $24.99 and can be purchased from the Nintendo eShop. The sixth and final wave of course is due by the end of 2023. The previous wave of courses for Mario Kart 8 Deluxe dropped in March, bringing a brand-new course, Yoshi’s Island, and a returning racer, Birdo, to the Switch game. The new course Squeaky Clean Sprint sends players into a suds-filled bathroom, where miniature racers will drive across a slippery tile floor, through a bathtub, and tracks made of towels. Nintendo still has a handful of candidates who can join the Mario Kart 8 Deluxe roster in future DLC. Kamek, a Magikoopa, is playable in Mario Kart Tour, but he was previously planned for Mario Kart 64, before being swapped out in favor of Donkey Kong.
Petey Piranha previously appeared in Mario Kart: Double Dash!!, while Wiggler was last seen behind the wheel in Mario Kart 7. Wave 5 of the Booster Course Pass for Mario Kart 8 Deluxe will add an all-new track, Squeaky Clean Sprint, and three new drivers to the playable roster: Petey Piranha, Wiggler, and Kamek. Mario Kart 8 Deluxe’s next wave of DLC courses is coming to Switch this summer, Nintendo announced Wednesday during its Nintendo Direct livestream.
