Marine Tour

The Marine Tour is the twenty-first tour of Mario Kart Tour that began on July 1, 2020 and will end on July 14, 2020. Due to being aquatic-themed, the tour introduced Rosalina in a teal swimdress adorned with Grand Stars and Mario in his swimwear from Super Mario Odyssey as the new spotlight drivers of the tour, while also adding in fish-themed kart parts such as the Cheep Snorkel and the Manta Glider. Additionally, Koopa Beach 2 from Super Mario Kart is introduced as the signature track since its last appearance in Mario Kart DS.

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.
