Sackboy (also referred to as Sackgirl; or the gender-neutral alternatives Sackperson, Sack Thing, or Sack) is the protagonist of the LittleBigPlanet games. He is a small, anthropomorphic creature made of fabric. Sackboy can be customized to the player's liking using costumes that are either unlocked in the game, or bought as DLC on the Playstation Network. Sackboy can express four emotions; happiness, sadness, fear and anger. The player controls Sackboy's expression, each of which has three levels of intensity.
