The "Play" section of "LittleBigPlanet" consists of several levels that have been created by Media Molecule, and are based around different themes that draw inspiration from real-world locations and events, including the deserts from South America, the streets of New York City, Japanese gardens, and the icy Arctic. By completing the levels available to them (by reaching the scoreboard), the player may advance the story and play further unlocked levels. The story mode comprises eight themed areas, with each area containing three or four main levels, and some of these levels, in turn, contain collectable keys to unlock bonus mini-levels. The main story mode comprises more than 50 pre-built levels in total.
