Bowser Jr. Cup
From the Super Mario Wiki
Its courses are based off of the cloud worlds from the New Super Mario Bros. series. Its courses also contain a few references to the Super Mario Galaxy series, which both games contained a lot of Airships, which are commonly found in the Bowser Junior Cup.
The cup reappears in Mario Kart Tour as the fifth cup of the Tokyo Tour.
