Baby Rosalina Tour

The Baby Rosalina Tour is the thirteenth tour of Mario Kart Tour that began on March 11, 2020 and ended on March 24, 2020. It is the first tour to be named directly after a character, and the second tour to introduce only one spotlight driver: Baby Rosalina in a detective outfit, while Waluigi (Bus Driver) returns from the London Tour as the spotlight driver for the second week. Additionally, Rosalina is made available as the third Super spotlight character after the Mario Bros. in the Mario Bros. Tour. London Loop is once again the featured course of the tour through the new course London Loop 2, a reference to the fact that, a famous fictional detective, is based in London.

Starting with this tour, the player can earn Grand Stars to unlock two free pipe launches from the first pipe in addition to Tour Gifts. Grand Stars are also no longer required to unlock cups; the tour features only 12 cups, the first seven of which are available from the start and can be played in any order, while the rest are locked by the usual availability timers.

Signature kart sets
In every cup, the driver which the cup is themed about is raised a tier on each track, making them a three- or two-item driver on that course. Up until the Ice Tour, a kart and a glider were also given a bonus for each race in the cup.

Rewards
Gold cells indicate rewards exclusive to Gold Pass members.

Initial pipe appearance rates
Like the Mario Bros. Tour, these pipes hold 50 drivers, karts, and gliders rather than 100.

Trivia

 * Hammer Bro, who appears as the opponent in the Rosalina Cup's bonus challenge (marking the first instance of a driver appearing without being playable), can be seen in a Pipe Frame within Baby Rosalina (Detective)'s magnifying glass in the splash art and the trailer for the Baby Rosalina Tour.
 * When the tour began, the English Mario Kart Tour Twitter account accidentally uploaded the Japanese trailer for the introductory tweet. The English version of the trailer was later added in a correction tweet.
