You blink as you glance at Harry's face. He's got hair growing out of his forehead and around the perimeter of his eyes, nose and mouth. His nose has flattened considerably. His shoulders and chest are wider. You turn back to focus on running. Harry's turning into some sort of monkey, you think uncertainly.
Now you realize that your are running using your knuckles as well as your feet. You don't have to bend over for your knuckles to carrying you across the turf. Something about this seems wrong, but you can't quite place it. You and your troop are racing around the field at a record pace. Zeb's coming up on your right. He's got something yellow in his hands. Your mouth start's to water. The scent smells delicious. It must be some exotic banana, because it smells better than anything you've ever smelled before and you must be 25 yards away.
Zeb calls out, "Faster, monkeyboys! The first one to complete all your laps gets this banana!"
You redouble your efforts. Two more laps to go, and you're drooling like an animal.
