Banana Cup

The Banana Cup comprises four courses, each of which is taken from the nitro cups of previous Mario Kart games: the Mushroom Cup, Flower Cup, Star Cup, and Special Cup. The cup's symbol is a Banana Peel, and the cup's tracks are slightly more difficult and/or longer when compared to those of the Shell Cup. Its length and difficulty is on par with the Flower Cup. the Banana Cup also returns in Mario Tennis Open for the Nintendo 3DS. It appears after the Flower Cup and before the Champions Cup.

Mario Tennis Open
In Mario Tennis Open, the Banana Cup is the third cup in the World Open series. It is played on the DK Jungle court, and matches have one set for the starting round, three sets for the semifinals, and five sets for the finals. This cup can be unlocked by beating the Flower Cup, and once beaten will unlock the Champions Cup. The CPU difficulty is one step harder than that of the Flower Cup's.

Trading Card info
"The Retro Cup racing festival peels off four challenging drives with the Banana Cup. It consists of one track from N64, one from Game Boy Advance, one from DS and one from GameCube...all with somewhat challenging levels of difficulty for Grand Prix or Time Trials competition."

Trivia

 * In Mario Kart 8, this is the only cup in the game with all courses taking place in the daytime, and is the only Banana Cup so far to have this trait. It is also one of two cups in the game to use the same character as Staff Ghosts in two tracks of the same cup (being Peach in Dry Dry Desert and Royal Raceway), the other being the Egg Cup (being Mario in Excitebike Arena and Mute City).
