Yupperz it's Monstro :]
All the worlds in Kingdom Hearts II are: Twilight Town, Hallow Bastion, Land of Dragons, Beasts Castle, Olympus, Disney Castle, Space Paranoid, hmm that black and white world, Atlantica, Port Royal, Halloween Town, Agrabah, Pride Lands, Hundred Acre Woods and The World That Never Was =]

Question: In Kingdom Hearts, there are white mushrooms (The little dudes with the red mushroom cap >.>)... If you perform the same spell on them three times they'll give you say a Gravity Art because you casts Gravity three times ect... When you have all the arts for each of your seven spells what can you do with them?? :]
