Ty saw how well thr satyr transformation went, so decided to do a centaur next. That was when he noticed Brian. A 17-year old, decent height, decent all around. He had brown hair, cut short, and no facial hair. Ty got to work.
First, Ty wished everyone in the class, including the teacher, was barefoot. That way, shoes and socks wouldn't become a future issue. Then, he focused on Brian.
Brian, long since zoned out on Mr. Moldreich's lesson, absentmindedly scratched his leg, just like Jimmy had been doing. His toenails grew over his feet, and turned black. Instead of becoming heavy goat hooves, they became finer, horse hooves. Fine fur began climbing up his legs, rich brown in color.
His legs became thinner, but not weaker. The fur had stopped at his belly button. His body began to grow backwards, still covered in fur, mostly around the butt. New legs grew out of it, fully formed horse hindlegs. Ty barely made the chair disappear in time. Ty also decided now was a good time for the clothes to pull a Houdini, since Brian was furry waist down.
Brian's spine continued back through this new appendage. His new body part grew back the length of a horse's body. He was standing now. After his new body appendage was complete, his spine pushed out through his new butt, covered in horsetail fur.
His hair had grown longer, down to his shoulders. His nonexistent facial hair filled in nicely, a light goatee. His ears pointed slightly. Even his IQ, previously pathetic, grew larger, encompassing his new centaur physique. His decent muscles bulged slightly, his 6-pack now very defined.
Brian was now fully centaur. Ty wished him a bow and quiver full of arrows, as well as a nice patch of grass to lay down on. Now very smart, Brian focused all attention on the lesson.
"Why can't you all be like Brian?" Mr. Moldreich asked the class.
"Very nice, Ty thought. "Who, and what, next?"
