Meadow
Left alone, the collie wanders and makes short herding runs. Click the collie by the tree to herd sheep with the pointer; click again to put the dog down. D selects or drops the dog, and arrow keys move it. Click grass or an existing sheep to add a sheep. Drag a sheep to move it; drop it onto another to stack them. Arrow keys move the landing marker, G picks up a nearby sheep, Enter or Space adds or drops one, and Escape releases it.
