This page details content that was left out of LittleBigPlanet Karting.
For some odd reason, LittleBigPlanet Karting's Youtube Gaming page has a screenshot of an early build of the game. Two notable things that are present a green bubble pointing to the player with "DRIFT!" displayed on it, and two squares in the bottom right corner. There is a scoreboard in the distance, which is not there in the final game.
