Sundae Tour (2023)

The Sundae Tour is the hundred-and-fourth tour of Mario Kart Tour, which begins on September 6, 2023 and ends on September 20, 2023. The tour features the first reappearance of Sky-High Sundae following its debut over a year prior in the previous Sundae Tour. The tour also features many snow-themed courses, including the introduction of a new remix course based on the Vanilla Lake courses, named RMX Vanilla Lake 2, marking the first instance of two RMX courses being based on the same SNES course since the Peach vs. Daisy Tour introduced RMX Choco Island 2 over two years prior. This tour also introduces the R/T variants for SNES Vanilla Lake 2 and RMX Vanilla Lake 1.

Additionally, this tour introduces a gold variant of Wiggler, as well as a kart based on the Wild Wiggler from Mario Kart 8. A variant of the Strawberry Soft Swerve themed around chocolate and mint is also introduced, as well as a gold variant of said kart. Multiple variants of the Mint & Berry Balloons are also introduced, one being Halloween-themed despite the tour's release in September, and another being yellow and green.

Much of the courses in this tour last appeared in the 2022 Holiday Tour. This is also the first tour since the 2022 Cat Tour to feature N64 Frappe Snowland R/T, and is the first tour to feature GBA Luigi Circuit following its debut in the 2023 Mario vs. Luigi Tour, as the only non-snow or ice-themed track to appear in the game; instead it features rains.

As of this tour, all regular Mii racing suits from Mario Kart 8 are present in Mario Kart Tour.
