After the credits are finished you see Sora, and Riku at their old hang out on Destiny Islands talking about how a whole lot has not changed. Then Kairi comes running with a bottle in her hand that has a note contained inside it. The note is from the king which is insinuating that he is asking for their help.
A special bonus movie can be seen after the whole credits, but it can be only accessed if you complete the game close to a 100%.
While the credits are rolling you see scenes of various Disney characters and characters from the game, end with a happy ending.
