The starting grid is the main feature of the Mario Kart series. It can carry eight or twelve racers at the start of every race. The size of the grid varies depending on which game you're playing. Once all of the characters are in their respective places on the grid, Lakitu will come in to begin the countdown to the start of the race. The racers leave the grid when the green light on the Start Signal comes on. Mario Kart: Super Circuit's grid has little boxes in which racers rev their engines.
