Donkey Kong Cup
From the Super Mario Wiki
The Donkey Kong Cup (known as the DK Cup in the first two Mario Kart Arcade GP games) is a cup that appears in the Mario Kart series. It first appears as the second of the six cups in Mario Kart Arcade GP and subsequently appears as the second normal cup in Mario Kart Arcade GP 2. In both games, the DK Cup features two tracks that are themed after Donkey Kong, more specifically the Donkey Kong Country series, and are shared between the two games.
In Mario Kart Tour, all courses featured in this cup have Donkey Kong as the primary or secondary favored character.
