On the other hand, Nergal Junior uses his transformation powers to get in shape at will and excel in every test. Billy asks Junior to transform into a pair of pants for him to wear so he can run fast and win the 50-meter race. Since Junior has never tried to transform into inanimate objects, he can't stop running and can't return to his human form. Billy continues to run endlessly, becoming a national sensation known as "Fitness Boy." It is revealed that the story was just a fabrication created by the narrator, who parodies The Twilight Zone.
