Sheepish:

Perhaps you've seen frogs cross roads. They do it all the time.
But sheep? Can sheep cross highways? You'll soon find out...

Use your arrow keys to help the sheep across the road (watch out for cars), over the river (sheep don't swim too well so stick to the floating wreckage), and finally into one of the unoccupied sheep pens (not the grass) on the other side of the river.
