What is the last thing that happens in Kingdom Hearts

Cutscene wise? If you've played through the entire game and had the skill to collect everything in it, you'll be blessed with a secret epilogue that gives you a sneak peek into the events of Kingdom Hearts 2. If that cutscene is not available to you, you'll see Sora, Goofy, and Donald following Pluto down a pathway with a letter in his mouth from the King. Overall, Sora and friends defeat Ansem and Kairi returns to the islands while Sora ventures off to find Riku.
