The Birthday Girl (known as Royal Ribbon in Europe and Australia) is a kart part that resembles a shoe with ribbons. It is usable in Mario Kart 7. As its North American name implies, it is a kart part that is primarily designed for female characters, but it can also be used by the male or indeterminate-gender characters such as Mario and Luigi, although male or indeterminate-gender computer racers are not seen on this kart. It offers a high acceleration and handling boost, while its speed, weight, and off-road are hindered.
