The mini-game "Jump, Man" involves the player racing against Donkey Kong by running up ramps and jumping over rolling barrels to reach the goal at the top of the stage. This mini-game is a reference to Donkey Kong and its name references Mario's earlier name, Jumpman. Toadsworth's description of the mini-game hints at these similarities with the last line: "Say, this looks familiar..."

Using Action Replay codes, it is possible to play as the Red and Green Koopa Kids. Their character models and behaviors are mostly broken as they are missing several animations, all voice clips (as they use Mario and Luigi's) and party board HUB sprites. There is a value for the Blue Koopa Kid as well, however using the code will make the game crash.
