Sheep

n SHEEP you control a sheepdog (named "Shep"), trying to herd a bunch of sheep into a barn. The use of the p character for the sheep was an inspired choice—when I was young, I knew nothing about the Greek alphabet or the mathematical constant pi but I did think that the character resembled a sheep or a small dog. The sheep are hard to control; they are afraid of your dog and will sometimes dart clear across the screen when you get too close to them.
