Keelhaul Key

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.

Luckily for Mario, the ocean washes the whole crew up to Keelhaul Key itself. Mario will now have to face the dangers of the jungle in order to save his lost crew mates and find a way into Pirate's Grotto, in which the Sapphire Star lies. With the help of Flavio's Skull Gem, Mario makes it inside. At the end of Chapter 5, Mario faces off against Lord Crump in his ship at the shore of Keelhaul Key. After completing the Chapter, the player may return to the southern island on Cortez's Ship, Black Skull, whenever they want. Cortez's Ship will be in Rogueport at all times. There is also a pipe in Rogueport Sewers which Mario can take to Keelhaul Key.

Keelhaul Key is the only place in which Mario can find Keel Mangos, used for a variety of recipes. Additionally, in Keelhaul Key, Mario's last party member, Admiral Bobbery, joins him. Mario can also find several badges and items on the island. After the island goes back to normal activity, P-Patch, the two Toads who run the shop and inn, and a few of the Bob-ombs will stay on Keelhaul Key and run a settlement. Don Pianta's daughter, Francesca, and his son-in-law, Frankie, also decide to stay in Keelhaul Key. Creatures in Keelhaul Key include Embers, Flower Fuzzies, Green Fuzzies and Putrid Piranhas.

Trivia

 * The adventure Mario has on Keelhaul Key is very similar to the one he has on Lavalava Island in the first Paper Mario. Both are for the fifth collectible (Star Spirits and Crystal Stars, respectively), and both are underground on a tropical isle. In both, Mario goes with a famous explorer on a treasure hunt, and Podoboos, Buzzies, Fuzzies, and Putrid Piranhas are also present in both. Both places can be later accessed by pipe in the sewers. The player also gains the ability to swim on both, by using Sushie on Lavalava Isle, and Boat Mode in the Pirate's Grotto. Both end successfully, as Kolorado gets his Volcano Vase treasure and Flavio remarks in his diary that he got whatever the player used to convince him to sail them to Keelhaul Key (romance, thrills, or emotion).
