I suppose the earlier association to rabbits explains the kangaroo in the hole. Maybe the Saberoo led to thoughts of mammoths. In any case we have an unlikely kangaroo (in a hole) surveying a Pleistocene plain with a herd of mammoths in the background. The base scenery was created in Terragen using a bitmap developed in Elements. The mammoths are a modified Photo Object and the tree was extracted from a stock photo. The grass is a standard Elements brush.
