The Candy Kart is the current kart under the possession of Vanellope von Schweetz. Her previous kart, the Likkity Split, was destroyed by Taffyta and the other racers in an attempt to keep her from entering the Random Roster Race.
In exchange for the return of his Hero's Duty medal, Vanellope had Ralph break her into the Kart Bakery and help her make a new kart so she can enter the race. The two go through the mini-game with several mishaps, including smothering the kart in frosting and sprinkles, and destroying much of the machinery. Despite all this, Vanellope is thrilled and ecstatic to have a real kart. The two are just signing their proud creation when they are interrupted by King Candy and the security team.
Vanellope reveals to Ralph she does not know how to drive a real kart, and so the two barely escape into Diet Cola Mountain with Ralph's brute strength alone. Later on, Ralph makes a track for Vanellope to practice driving on, and she learns remarkably fast.
Sometime later, King Candy deceives Ralph into thinking that Vanellope's glitching will cause the gamers to think the game should be unplugged and that Vanellope will die with it. This causes Ralph to destroy the Candy Kart "for Vanellope's own good" to save her life.
When Ralph returns, he discovers the truth by interrogating Sour Bill, who is sweeping up the remains of the kart into a trash bin. Taking the scraps, Ralph breaks Fix-It Felix, Jr. out of the fungeon and implores him to fix the kart with his magic hammer. After repairing the kart and rescuing Vanellope shortly after, all three head off on the Candy Kart to the Random Roster Race, and Vanellope drives off to try and cross the finish line.
