A Carnival On The Run serves as the first cutscene of LittleBigPlanet PS Vita's Story Mode. It is one of two total cutscenes found in La Marionetta.

The cutscene tells the story of Carnivalia's misfortune and the travesty that struck as soon as The Puppeteer became corrupt. At one time he had held shows that entertained the citizens of this humble planet, but as soon as he lost the attention of his audience, he began to construct an army of mindless puppets to do his bidding.
