The Caribbean

The Caribbean is a world in Kingdom Hearts III. It is based on the Disney film series Pirates of the Caribbean. It is an expansion to the Kingdom Hearts II world of Port Royal.

Development
The Caribbean was included in the game because Port Royal was a well-received and popular world in Kingdom Hearts II, and the developers wanted at least one live-action world in Kingdom Hearts III. It is based on the third film, At World's End, because the developers felt it was the most natural choice.

Kingdom Hearts III
Upon arrival in Port Royal, Sora, Donald, and Goofy sail a raft for fun, but are carried away by and fall into the abyss below. To their surprise, the fall dropped them into a vast desert. Trudging on, they see the Pearl in the distance and are soon joined by Jack Sparrow, who asks for help in catching his beloved ship, which is being carried off by magic crabs. However, they first had to destroy Anchor Raiders on board.

Riding the Pearl to the shore, the quartet meet Will, Elizabeth, Gibbs, Tia Dalma and a revived Barbossa, who reveal Cutler Beckett is taking over The Caribbean; Beckett has Davy Jones' heart, forcing him to obey his orders. Will and Elizabeth reveal to the trio thay they are in Davy Jones' Locker, an afterlife, and they have come to rescue Jack. Despite initial friction, Jack decides to cooperate if it means escaping the Locker. As they sail, Tia Dalma reveals Jack owes a debt to Jones and will be punished for escaping. However, Sora is not afraid of Jones or the Kraken who took Jack to the Locker, surprising her as his kind of bravery is rare. When she mentions a box a Jack is after, Tia Dalma explains it contains Jones' heart, which gives whoever has the chest leverage over him.

At the same time, Vexen and Luxord are in The Caribbean as well. Vexen is puzzled by how Davy Jones can live without a heart, believing it holds the secret to perfecting his replicas. Luxord tells him to reign in his curiosity, and allow him to collect the chest as per their orders.

After a green flash at sunrise, the Pearl returns to the living world. Suddenly, the ship is attacked by the Raging Vulture and a swarm of Vaporfly. Once Sora takes out Raging Vulture, the Vaporflies vanish and he falls into the sea. Donald and Goofy wake him later, revealing their friends left them and Jack on an island. Finding a new ship, the Leviathan, hidden in the island, they set sail and are surprised by a ship sailed by Luxord. Luxord asks to race to Port Royal in exchange for information about the chest. Despite summoning Heartless ships to attack, Luxord loses; however he manages to trick Jack into revealing the chest is on the Flying Dutchman and disappears.

The Leviathan docks at Port Royal for repairs; oddly, Jack says white crabs are needed for it. Once the ship is fixed, Jack asks Sora why he wanted a pirate ship. Sora answers he wants to sail as free as the wind, prompting an impressed Jack to reveal he was a copy sent by the goddess of the sea to help and that the real him and their friends are facing Beckett's armada at Shipwreck Cove.

Arriving at the battle, Sora learns Jack was taken hostage and Tia Dalma was really the goddess of the sea Calypso; the pirates freed her in the hopes she'd help them, but she vanished. However, Sora encourages his friends to keep fighting. The Pearl and the Dutchman enter a whirlpool, followed by the Leviathan. Luxord appears on Sora's ship, wishing to take the chest despite Sora telling him the Organization won't have use for it. Regardless, Luxord summons the Kraken to restrain the Pearl. Freeing the Pearl, Sora, Donald and Goofy board the Dutchman, where they help Jack fight Jones.

Will and Elizabeth join the fight, but Will is fatally stabbed by Jones. Sora, Donald and Goofy distract Jones, allowing Jack to help Will stab Jones' heart in the chest. Having been watching, Vexen is unimpressed with the chest's contents. Leaving Will behind, everyone returns to the Pearl; moments later, the Dutchman resurfaces with Will in command. Both ships fire on the Endeavour, killing Beckett and ending his reign of terror. Gibbs reveals Will was saved by taking on Jones' curse, but at the cost of having to ferry souls to the afterlife in exchange for one day a shore every ten years. Jack assures Sora that one day is enough for hearts to connect.

Later, after Xehanort's defeat, Elizabeth watches as Will leaves to carry out his duty. In Port Royal, Jack and Gibbs watch as the Black Pearl sails away.

Characters

 * The Brethren Court is mentioned.

Character Design
Unlike when Sora, Donald and Goofy previously visited the portion of the world near Port Royal, while visiting The Caribbean, they appear in proper pirate attire. As Sora is the de facto "leader", he appears in captain's garb, while Donald and Goofy wear crewman clothes.

Trivia

 * Jack's dialogue when he meets his allies in Davy Jones' Locker is censored. Originally, he remarks that "four of you have tried to kill me in the past; one of you succeeded"; in the game, it is changed to "four of you have tried to annihilate me."
 * Davy Jones' heart is not seen for the same reason, leaving it in the chest.
 * The Kraken is also still around, as opposed to the film, where it is dead. It replaces Davy Jones' crew in some scenes, where its tentacles knock people around.
