Keelhaul Key is the main area in which Chapter 5 of Paper Mario: The Thousand-Year Door takes place. Similar to Lavalava Island from Paper Mario, Keelhaul is a southern island disconnected from all kind of society of the outside world. During the events of Paper Mario: The Thousand-Year Door, Mario learns that the next location of a Crystal Star is in the southern island of Keelhaul key. Mario will soon find himself captain of a whole crew, which consists of Flavio, Pa-Patch, Four-Eyes (Lord Crump in disguise), two Toads, and some Bob-ombs. While on the trip to Keelhaul Key, the ship, the S.S. Flavion, is attacked by Embers and finally sinks.
