"Bull the Great Detective" begins with the narrator lamenting that he has not been able to catch the thief because he has been eating and napping. He says that he had planned to use the thief as a decoy, but the thief has struck again, so he has decided to wait for the thief in the shadows. He plans to eat some sweet bread and milk, and then go to sleep. He wonders if the narrator is the real culprit, or if his mother is relieved that he is not the thief. The narrator says that his glasses are useless, and that he would like to be a girl, but he knows that he cannot play the role of a girl because he is too young. He thinks that if he were a boy, he would be a good replacement for a girl. He imagines that he will be the chief of the ogres, and he thinks that he and the other animals will have to fight the monkey and the pheasant. He also thinks that the cat is the only animal that can live happily ever after, because it was returned to his grandparents after being eaten by the monkey.
