Alternate ending sequence
After finishing the game with all Keyholes locked (including The Book Of Pooh), 99 Dalmatians rescued, the Hades Cup won, and the Ultima Weapon.
Wait until the credits complete to view an epilogue of what happens to Sora, Donald, and Goofy after the worlds come back. It seems to be a teaser for another Kingdom Hearts game. After that, there is a "Special Secret" which seems to be a hidden trailer for yet another Kingdom Hearts game, although this one seems to be about Riku and what happens after the defeat of Ansem and the Heartless.
Atlantica - Final Fantasy prelude
In Ariel's Grotto, examine the music box to hear a little song, which is the Final Fantasy prelude.

Finish the Hades Cup Time attack to get the Save The King (Goofy's best weapon).
Save the Queen
Finish the Hades Cup alone (only with Sora). As a prize, you will get Save The Queen, which is Donald's best and final magic rod.
