Mametchi represented the Tamagotchi franchise in Mario Kart Arcade GP 2.
Mametchi is one of the best-known characters from Bandai’s virtual-pet series, first released in Japan in 1996. His inclusion was a notable crossover because Arcade GP 2 was not limited to Nintendo characters: Namco and Nintendo also brought outside mascots into the arcade racing series.
Mario Kart Arcade GP 2 was developed by Namco for arcade release and followed the original Mario Kart Arcade GP. It retained returning racers while adding Waluigi and Mametchi. The game also included franchise-themed items and courses, making Mametchi’s appearance part of a broader Bandai Namco crossover rather than a random guest spot.
A common mix-up is Pac-Man, who is also associated with the Mario Kart Arcade GP games and Namco’s arcade heritage. However, Pac-Man is not the franchise Mametchi represents. Mametchi belongs to Tamagotchi, while Pac-Man is a separate Namco property.
