Sackboy (or Sackgirl) is the name of the generic avatar in Little Big Planet Wii. The original version of the character, in the prototype Chaftworld, was dubbed Yellowhead and, unsurprisingly, had a large yellow head. Sackboy is made of sackcloth and stuffing, with stitches clearly visible at the top of his head, and a large zipper down the front of his/her chest. SackPeople are apparently only 8 centimeters tall.
