Ralph crash-lands in Sugar Rush, a kart-racing game. As he searches for his medal, he meets Vanellope von Schweetz, a glitchy character who takes the medal and uses it to buy entry into a race. King Candy and the other racers refuse to let Vanellope participate, claiming she is not really part of the game. Ralph helps Vanellope build a kart. At her home in Diet Cola Mountain, an unfinished racing course, he discovers she is a natural racer.
