This is the first (and currently only) Mario Kart course to start underwater.
Only about half of the music is played when racing on this course, and the other half plays only when watching a highlight reel. This feature is shared with Super Bell Subway.
On the final lap, the music plays only the faster jazz version of the music, unlike all other track music barring Mount Wario and Big Blue where the final lap music is simply a sped up, slightly higher-pitched version of the regular music.
On either side of the finish line, Toads wearing scuba diving gear can be seen swimming up and down.
