The film is set in 1837. The Pirate Captain, inexpert in the ways of pirates, leads a close-knit, rag-tag group of amateur pirates who are trying to make a name for themselves on the high seas. To prove himself and his crew, the Pirate Captain enters the Pirate of the Year competition, with the winner being whoever can plunder the most. After several failed attempts to plunder mundane ships, the Pirate Captain talks with his close first mate, the Pirate with a Scarf, about giving up and selling baby clothes as a living, but is convinced to try boarding the next ship they find, which happens to be the Beagle. They find no treasure but succeed in capturing Charles Darwin. Darwin recognizes the crew's pet Polly as the last living dodo, and implores the Pirate Captain to enter it into the Scientist of the Year competition at the Royal Academy in London for a valuable prize. The Pirate Captain directs his ship to London, despite being warned of Queen Victoria's hatred for pirates.Darwin desires to win the Scientist prize on his own in order to impress Queen Victoria, on whom he has a crush. He uses Mr. Bobo, his trained chimpanzee who was from an old theory that parodies his own theory, to try to steal Polly. The Pirate with the Scarf witnesses the kidnapping but the attempt goes awry after alerting the other pirates. Darwin avoids implicating himself much to the Pirate with the Scarf's frustration, but now the Pirate Captain insists on hiding the bird and entering the competition on his own. The display of the dodo takes the top prize: a minuscule trophy, an Encyclopedia set and an opportunity to meet the Queen. During the ceremony, the Pirate Captain accidentally reveals his pirate identity, but Darwin convinces the Queen to spare the Captain's life because he knows the location of Polly. The Queen lets the Captain go free with a full pardon, but orders Darwin to locate the dodo by any means necessary.Darwin takes the Pirate Captain to a tavern, and the latter ultimately reveals that he had stashed Polly in his beard. Darwin and Mr. Bobo are able to capture Polly and are chased by the Captain up into the Tower of London, where the Queen is waiting. The Queen quickly dismisses Darwin and Mr. Bobo, and then offers the Pirate Captain a large amount of treasure in exchange for the bird. Soon, the Pirate Captain reunites with his crew with his newfound wealth, stating that Polly is sleeping within his beard, and sets off for the Pirate of the Year ceremony. The Pirate with a Scarf expresses doubt to the validity of the Captain's story.At the ceremony, the Pirate Captain wins the grand prize from the Pirate King, but the Queen's pardon is discovered. The Captain is stripped of the prize, his plunder, and his pirating licensing, and on learning that he lied about Polly's fate, his crew abandons him as well. The Captain returns alone to London to sell baby clothes, but soon becomes determined to free Polly. He re-encounters a now-devastated Darwin, who has learned that the Queen is part of a rare animal eaters' club with several other world leaders who are now aboard her steamship, the QV1, waiting to eat Polly and several other rare animals. The Pirate Captain enlists Darwin's help to steal a dirigible and rescue Polly.Aboard the QV1, the Pirate Captain and Darwin disrupt the meal, and are soon joined by the rest of the Captain's crew, having been informed by Mr. Bobo of his need. The Queen locates them and attempts to kill both of them, but together they best her. In the battle, they accidentally mix the ship's store of baking powder with vinegar, causing a violent reaction that starts to sink the ship. The Pirate Captain rescues Polly and they escape safely, leaving behind a furious Queen.With his reputation among pirates restored because of the large bounty now on his head, the Pirate Captain and his crew continue to explore the high seas in search of adventure. They leave Darwin on the Galapagos Islands, where he finally finds a girlfriend, and Mr. Bobo joins the Captain's crew., Question: What does Darwin convince the Queen?
