When Buster inadvertently saves a cat, the cat's owner glorifies his "heroics" to Buster's mother, causing the incident to become headline news. Buster builds his fame up, causing him to become a "big-shot". Arthur, Francine, and Brain find out the truth and plan on showing everyone that Buster is not as big a hero as he makes himself to be. However, Buster gets another shot at fame when he saves his friends from a runaway piano. Meanwhile, Arthur is being constantly annoyed by D.W. and her "Crazy Bus" CD. D.W. is still playing her "Crazy Bus" CD (since "Buster Baxter, Cat Saver") and Arthur is annoyed by it, even angrily threatening that he will break it. When the CD goes missing, D.W. blames Arthur for taking it, with no one believing his denials.
