Mattress Village is a relatively small, peaceful, yet mysterious town nestled in a corner of Eastshield, on the border of Trans-Antarctica. It is reknowned as the source of several famous penguins, including the folks of Skybound, TurtleShroom's Family, Bob Johnson, Dan Beronews, Roy Dibbs, and That Trainer. It has a decent-sized and historic commercial district on its paved main street. Its resedential district, however, is as sparse as the countryside, though still in Unoian jurisdiction. It is here where now-famous penguins spent most of their chick years.
