Players continue Sackboy's journey after the events of the first game and the portable version are brought to an end. An inter-dimensional vacuum cleaner called the Negativitron appears over the skies of LittleBigPlanet and begins to suck up its inhabitants, including Sackboy. Larry Da Vinci, the leader of a group known as "The Alliance", comes to Sackboy's rescue - saving him from the Negativitron. The organisation is dedicated to battling with the Negativitron and defeating it before it destroys Craftworld entirely.
