Toby warns Daisy about bulls, but she claims that she would simply have to toot to scare them off. When Daisy is asked to shoo a bull back to its farmer, Daisy sees her chance but fails and runs away when the bull sniffs at her. Toby hears about the events and shoos the bull away, but Daisy is later teased by some boys when they offer her some "bull's-eyes" sweets.
