Walkthrough:Kingdom Hearts Re:coded/Darkheart3/Agrabah

Agrabah
When you get to Agrabah, keep walking through those sorta keyhole looking arches until you see a raggy old street guy. Talk to him, then make your way back the way you came. Street guy will ask you to look for his friend. Continue through the arch until you are prompted with a cutscene. Follow the sound, and prepare for your next boss battle.
