Kingdom Hearts/Agrabah

After leaving Traverse Town, you should now be able to travel to Agrabah. The world is based off the one seen in the 1992 Disney movie Aladdin. After a cutscene, get ready to fight some Heartless.

Finding Aladdin
From where you start, go to the Main Street and then the Alley. A cutscene will show Jasmine introducing herself to the party. Following that will be another scene, where you'll meet Jafar, who sends Heartless after you. After you get rid of them all, jump on the ledge on which Jafar introduced himself. Release the keyhole to open up a new path. Now jump across to the other area by using the windows. Here there will be another way to the Main Street. From the ledge you end up on, jump across from you and then across from that. An opening will lead to a pole you can climb on, which leads to Aladdin's House. Move the boxes to free the Magic Carpet. It will then fly off toward the desert, and you'll be prompted to follow it.

Explore and fight through to release more keyholes that open gates in the city first as Donald suggests. If you don't find Jasmine once behind the crates, Carpet will not spawn in the Desert area. Jump through the opening in the wall down to the Main Street. Go back to where you started in the Plaza. Past that will be the Desert. The Magic Carpet will land next to a Save Point. Press psx: X next to the Magic Carpet and then All Aboard to ride it. Following that will be a cutscene. Fight the area's Heartless to save Aladdin, and he will then summon Genie to get rid of the remaining Heartless. After a couple more cutscenes, you will be able to add Aladdin as a party member. After another cutscene, you'll be back at the Plaza.

Finding Jasmine
Go back to Aladdin's House for another short scene and then head back to the Alley. Go through the upper path to the Main Street and head to a path leading to the Bazaar. Jump across the windows and jump up onto the higher ledge. Release the keyhole and go back to the Main Street. Jump up the ledges leading to Aladdin's House, then jump across to the path you opened with the keyblade. It should take you to the Palace Gates, where you'll see Jafar and Jasmine. Jump down to get noticed, and Jafar will address Sora and Aladdin. Jafar will then get a hold of the lamp and escape, and you'll be left to fight your next boss.

Cave of Wonders
You must now head to the desert, where a cutscene will be followed by another boss fight.

After the battle is over, you'll be able to enter the Cave of Wonders. Entering will have you greeted by none other than the Heartless. Go down the stairs to the side of the main path, and you'll fall into a pool of water. This is known as the Relic Chamber. Go up the waterfall into the Dark Chamber. A Save Point is located on one of the platforms in the room. If you don't have Aladdin in your party, replace Donald or Goofy - whichever you prefer - as Aladdin is necessary for one of the coming tasks. Treasure chests will be scattered all about so be sure to collect the treasures hidden inside. Swimming up the waterfall will bring you to the Dark Chamber. Swim up the next waterfall to enter the Silent Chamber. Here, go down the waterfall to see a statue holding a glowing stone. Climb up in front of it and press psx: up lstick, then psx: X to tap it with your keyblade. It will open up a secret door. Go back to the Relic Chamber through the shortcut here and climb up the stairs across from the second statue. Call Abu to tap on this statue's stone, and stairs will rise, allowing you to get to the platform the statue is located on. A passage behind the statue leads to the Dark Chamber. From here, jump off the platform and to the waterfall. Swim in front of the first statue and once again, call Abu. A new path will open. Through the new shortcut, go to the Silent Chamber. Go through the passage here to the Hidden Room. In this room, climb up the stairs and examine the pillar across from you. Lock on with psx: R1 and blast it with Fire. You can now leave the chambers and go up the higher area where you started. Go through the path leading to the Treasure Room, then the Lamp Room. Here, you will have a boss fight against Jafar.

Jafar
Move on forward and, after a cutscene, go through the door for another cutscene. Jafar will transform into a genie, becoming the final boss of Agrabah.

After Sora locks the world, you'll have to escape the crumbling Cave of Wonders by navigating past falling boulders with the Magic Carpet. You'll be able to leave the world after another cutscene, in which you will gain the ability to summon Genie.
