Lakitu is the friendly referee that has appeared in every Mario Kart game since the series inception. He will perform various helpful duties throughout the race and battle; most importantly, he will start the race or battle by using his Start Signal's Pre-race countdown. If the player is driving in the wrong direction, he will appear holding a "Wrong Way" sign until he/she turns around. After crossing the finish line, he will appear to indicate the lap the player is on or wave a checkered flag to indicate the race is over. And, of course, if the player falls off the track or goes out of bounds, he will use his fishing pole to get them back onto the track. In Super Mario Kart, Mario Kart: Super Circuit and Mario Kart 7, Lakitu charged the player coins to drop them back onto the track.
If the player taps the Acceleration button just as they hit the ground after Lakitu drops them onto the track, they can perform a recovery boost.
Mario Kart 7 is the first time that Lakitu is made available as a racer. As in all other Mario Kart games, he resembles a turtle on a cloud. This Lakitu has a red shell opposed to the referee, who has a green shell.
