In-game cameos
Being developed by Nintendo, there are various references to their most popular franchise. Mario and various characters from the series appear throughout the game. Depending on how points you've acquired in a round, you'll get an image of Mario dressed in clothes originating from different countries. In order of their appearance, the different clothes Mario will wear come from Mexico, Africa, Spain, India, China, and England. The final clothes are the clothes they normally wear in the game (the final one also contains Luigi, Peach and Toad in a traditional Mario setting).

In the multiplayer mode, the first team is known as Team Mario while the second is Team Luigi.
