The residents of Mathoura have had a long running battle controlling an elusive creature that's rarely seen in daylight but is very widespread right across Australia and, indeed, the world. In fact, almost every household is infested with at least one and usually a number of these creatures. Unfortunately, these creatures sometimes carry a very aggressive and destructive pest within them.
Through diligent efforts the residents have managed to collect a large number of OverTheShoulderBoulderHolders and have hung them on a fence in town in the hope that their untimely destruction will lead to the ultimate eradication of the dreaded Breast Cancer bug.
