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 return of Sky-High Sundae following its debut over a year ago in the previous Sundae Tour. Alongside Sky-High Sundae is the return of many snow-themed courses from the series, as well as introducing a brand new remix course based on the Vanilla Lake courses, named RMX Vanilla Lake 2. The tour also introduces 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 version of the Wild Wiggler from Mario Kart 8. A chocolate and mint variant of the Strawberry Soft Swerve is also introduced, alongside a golden 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.

This tour features the first reappearance of N64 Frappe Snowland, Wii DK Summit, and 3DS Rosalina's Ice World since the 2022 Holiday Tour, the first reappearance of DS DK Pass since the 2023 New Year's Tour (thus making this the first tour to feature DS DK Pass N, R and T since the 2022 Holiday Tour), the first reappearance of RMX Vanilla Lake 1 since the 2023 Doctor Tour, and the first tour to feature SNES Vanilla Lake 2 since the 2023 Exploration Tour.
