In Sugar Rush, a girl named Vanellope von Schweetz steals Ralph's medal and uses it to buy her way into the nightly race that determines which characters will be playable the next day. King Candy, the ruler of Sugar Rush world, forbids her to race, as she is a glitch that moves and teleports erratically. Vanellope promises to get the medal back if Ralph helps her win; he helps her build a new kart and teaches her to drive inside Diet Cola Mountain. Calhoun and Felix arrive in Sugar Rush, where they fall into "Nesquik-sand", work together to escape, and begin to fall in love. Meanwhile, Candy hacks into Sugar Rush source code and retrieves the medal, giving it back to Ralph. He claims that if Vanellope becomes a playable character, her glitching may lead to the game being labeled out of order and unplugged. Ralph decides he cannot allow Vanellope to race and destroys her kart. Calhoun abandons Felix when he inadvertently reminds her of her late fiancé who was killed by a Cy-Bug during their wedding; Felix is imprisoned by Candy's assistant, Sour Bill, while Calhoun discovers that the Cy-Bug has multiplied exponentially.
