"I want to be a bull!" You shout at the man.
The man twirls his fingers. Suddenly a ray of light shoots from his fingers, and hits you in the chest.
When this happens, your whole body tingles. Then your ears shoot out from your head. Above your ears, on each side of your head, horns shoot out.
Next you bulk up as your skin turns into brown hide. Your clothes rip and tear. Then your feet and hands become hooves. Next a brown tail grows out the bottom of your spine.
