A cottage sits in the woods. Grandmother (magenta=6) rests in bed at the top-right. The wolf (grey=5) approaches the cottage from the left while Little Red Riding Hood (red=1) is still far away on the path. In the masked grid, the wolf has entered the cottage and replaced grandmother in the bed — grandmother's cell now shows the wolf's value, while grandmother has vanished. Red Riding Hood continues approaching, unaware.
