Baby Kart Wii is the eighth installment in the Baby Kart series. Just like every other Baby Kart game, Baby Kart Wii includes new features such as new race courses, along with other older that appeared in past Baby Kart games, more like its predecessor Baby Kart DS. New items and characters were included, as well as an increased number of players for the races. Baby Kart Wii also introduced the use of bikes that vary in capabilities along with the classical karts. Game modes are also present such as the Grand Prix, Versus, Battle and Time Trial, many of them making use of the Nintendo Wi-Fi Connection for worldwide online play.
