While Haley is looking for something in Jake's room to take for show and tell, Jake comes in and kicks her out of his room. When Haley starts crying, Jake opens the door, lets Haley in, and they start talking about her problem. It turns out that a girl in Haley's school named Olivia Mears is always the best show-and-teller who always brings in her pet cat named Miss Tinkles. Jake then convinces Fu Dog to allow Haley to use him for show and tell. Fu Dog is reluctant to do so at first, but Haley negotiates with Fu by promising him sloppy joe.
When Haley brings Fu Dog to her school, the other students are amazed by him. Some kids start petting him, while other kids pull on his cheek folds. Fu Dog almost blows Haley's cover when he starts talking, but Haley manages to cover for him by telling the other students that he barks in Chinese. Later, one kid asks Fu Dog to eat his homework, which he didn't finish, and Fu happily obliges.
When Haley leaves for lunch, Fu Dog is left alone with his enemy, a cat. Not just any cat, but Olivia Mears' cat, whose real name is Yan Yan. It is revealed that she has the lucky coin that belonged to Fu's father, and the two archenemies start battling again. While they are fighting in the classroom, they remember their previous battles. When the two begin to break everything in the classroom, Fu Dog points out, "We're causing some real damage here!", to which Yan Yan replies, "Don't we always?" They then start to recall when the Titanic crashed into an iceberg in the middle of the Atlantic Ocean, or in Italy when they turned a building into the Leaning Tower of Pisa, or in Egypt when they broke the nose off the Sphinx.
Their battle is soon taken outside the classroom. Later in the cafeteria, Fu Dog grabs a bowl of sloppy joe and throws it at Yan Yan. When Yan Yan tells Fu Dog that there is no way he will be able to hide the lucky coin from her, Fu swallows it so Yan Yan can't get to it. When Fu Dog goes back into the classroom, he closes the cat cage and then goes into his own. When the teacher and students come in, they see the mess. They see Yan Yan outside, thinking she did it all. As a result, the teacher tells Olivia Mears she cannot bring Yan Yan to school anymore, and makes her take her cat out of the classroom. Haley then starts show and tell with Fu Dog, and they later begin to negotiate the sloppy joe deal again.
