Sugar Rush has never been sweeter than now with Vanellope and her new friends taking good care of it. It has been ten years since the incident with King Candy - or Turbo, if you will - and Vanellope couldn’t have a stronger bond with her new family; Taffyta, Rancis, Candlehead, and Gloyd. Not to mention a certain Stinkbrain.Then Sugar Rush experiences a sudden unplug. Ralph is out of his mind with worry, along with first time parents Felix and Calhoun. A week later, Sugar Rush is plugged back in. They’ve had an upgrade. As far as they can tell, the only major differences are the upgraded graphics and redesigns of the characters, karts, and landscapes. The racers look more sophisticated and older, the karts are faster and more high tech, and the scenery couldn’t be more beautiful. However, the upgrade unearths more than just a few secrets. New worlds and racers are being unlocked and a new(or shall we say old?) enemy appears. What are a princess and her Admiral Underpants going to do?
