For generations the opposing tribe of red squirrels have dominated the Finchster family's yard where The Great Oak grows. This monstrous ancient of suburban deciduousness provides plenty of acorns with which the red squirrel tribe members survive and thrive through the harsh Midwestern winters. Your tribe of gray squirrels, occupying the Sterzinski family's half-acre, however, are on a path to extinction. The Great Gray has summoned you and all of the other gray squirrels in your tribe to the toolshed for a meeting. The last strings of Autumn are here. It is becoming frigid in the suburb, and the tribe is becoming hungry.
