Oooh, oooh! you cry. That can't be good.
An attractive woman with her hair tied in a bun wearing an oversize lab coat comes over with a clip board.
"I'm Stacy, little fellow, now relax, and let the changes come naturally. In the next phase of the experiment, I'll oversee your subsequent changes, now you have a choice. Since you can't speak. Point to the ape you wish to become, and I'll modify your treatment to obtain the result." She holds up a laminated chart with different apes pictured. You reach your finger through the grill of the cage and point to the orangutan.
"Good choice, we don't have any orangs yet, so you'll stay male. Bobbo--I mean Bob-- your roommate picked chimpanzee, and we already have a male, so his change is bit more intense than yours will be."
She walks over to a small refrigerator, and comes back with an orange vial and syringe. She warms the vial in her hand, then draws some of the liquid into the syringe. She comes over and injects your right butt cheek. You howl and jump forward.
You feel hotter. Dizzier. Burning liquid courses through your veins.
You feel more changes beginning. Joints crack, bones twist and muscles grow.
