With the recently announced release date of LittleBigPlanet Vita and an over abundant of previews rolling in, we now have an interview with Tarsier Studios via psmania.net! Although this interview isn’t the most informative because LBPV is nearing release, there isn’t much new to talk about. But I found this interview nice to read about while we wait 
PSM: Tell us about the planet Carnivalia and the story in the campaign of LittleBigPlanet Vita.
Tarsier Studios: Carnivalia is a travelling fairground planet. It wanders around the universe spreading joy and laughter, but the story in LBP Vita picks up at a point in Carnivalia’s history when things have gone bad. At the beginning of the story, all we know is that a mysterious character called The Puppeteer is responsible for Carnivalia’s ills, and it is up to Sackboy to stop him.
