- “Look, Daisy! I've got some sweets; they're called bulls-eyes! I like them. Do you?"
"Humph! Keep your old bulls-eyes!”
- ―A boy and Daisy
Toby's cowcatchers and sideplates are designed to prevent animals from getting hurt if they stray onto the line, but Daisy thinks they look ridiculous and believes that Toby is simply afraid of getting hurt himself. She tells Toby that any animal, even something as big as a bull, will always run away if she toots her horn and looks them in the eye, despite Toby's insistence that they will not. Later that day, Daisy is asked by a policeman to guide a stray bull back to its farmer. She sets off, eager to prove to Toby that she can handle bulls, despite the fact she has never actually encountered one before.
Although not really very fierce, Champion the bull had been cross that morning, which resulted in him jumping the fence and sliding down the valley onto the line. Just as he begins to eat the nearby grass, Daisy arrives and toots for him to move. Despite several attempts, Champion ignores her and continues eating. Eventually, he notices Daisy and advances curiously towards her. Daisy becomes unnerved, as the bull is not running away as she expected him to and she is scared that she might get hurt, although she tries to deny this. Champion then sniffs Daisy. This proves to be the last straw, as Daisy retreats back to the station.
Toby soon learns about what happened and after reminding Daisy that a bull should always run away according to her, goes to shoo Champion away himself. Although Toby's bell and whistle prove ineffective against the still-grazing bull, he eventually retreats after Toby blows steam at him and reunites with the farmer further down the line. Later that evening, some boys tease Daisy with some "Bulls Eyes" sweets, much to her annoyance.
