The first Sackperson was shown at GDC 2007 to the public, for Media Molecule's new video game LittleBigPlanet. Sackboy was what Media Molecule named their little Sackperson. Players would enjoy Sackboy's many emotional, however funny expressions. Examples are, sad, angry and happy, from this point Media Molecule knew they gained the public's attention. Sackboy can wear many customizable costumes and colors at once, giving the player enough things to devise their own little sackperson. Sackboy's first costume was from Killzone's helghast trooper armor. From that point, Sackboy has been seen in many other costumes.
