Kingdom Hearts/Destiny Islands
You wake up in a beach, where you are introduced to Sora's friends, Kairi and Riku. It turns out you are building a raft to leave the island and explore new places. It's only a couple of days away from being finished.
You start here. It is the main side of the island. There is a tree house, a dock, a beach, a cave, a shack, a waterfall, and a smaller island. You can battle Tidus, Selphie, and/or Wakka here, Riku on the first day. Sora, Riku, and Kairi play in this part of the island the most.
Treasures: No treasures here.
 Seaside Shack
Just an old shack with stairs to the smaller island, and a Save Point. Use it if you have to.
Treasures: No treasures here.
Another side of the island. There is a bridge over shallow water with a few gaps. Part of the bridge is breakable. It has a watch tower with stairs beside it. The raft is built there. there is a ramp that leads to a cave back to the Seashore. There is also coconut trees where you can jump on. there is also a small cave, but not important.
Treasures: Protect Chain - Near the stairs, a crate is there. Push it below an out of reach cave. Use the crate to jump there, and open the chest.
 Secret Cave
This is where the trio draw pictures on the rocks at. There is a door here for some reason, but it doesn't open. First discovered by Sora and Riku when they are still little.
You start near Kairi. Talk to Kairi and she will tell you your task is to collect items to build a raft.
The best person to train with is Tidus since you will gain the most experience and technique points. He will attack you with his stick and if you deflect it you'll receive 2 technique points. If you press ATTACK before he attacks you, you will deflect it. And since he takes no damage by his stick, you can do it again and again or you can just go up to him and start attacking. Similar methods can be used with the other characters for practice fights, though each of them vary in difficulty.
 Wakka, Selphie, and Tidus
- HP: Same as the individual characters
- EXP: Same as the individual characters
- Recommended level: 6+
After you defeat all three individually, you can talk to Tidus to fight all three together. The best way is to focus on Selphie, and only dodge Wakka and Tidus. Once Selphie is KO'd, focus on Tidus. After that, it's just like fighting Wakka by himself, except you probably will have less HP.
Winning nets you a potion.
 Day 2
If you go through the door in front of which Kairi was standing the previous day, you come through to the Cove. Kairi tells you your task is to collect provisions for the raft.
- 2 coconuts: just hit the coconut trees (the thicker ones) until they drop yellow coconuts (ignore the brown ones, they don't count)
- Drinking water: wade into the area by the waterfall (under the bridge with broken planks) and fill up the bottle where the water drops down.
- 3 fish: find them out in the ocean, back on the beach
- Seagull egg: still on the beach, go up to the ledge that connects to the island. There are three trees. Climb the skinny tree and jump to the top of one of the others to get the egg.
- 3 mushrooms: one is in the secret area by the waterfall, go all the way to the end, it's to the right of the door. The other two are back in the cove area - one is near the base of the wooden tower, the other is near the raft, behind a boulder (push the boulder out of the way)
Speak to Kairi when you are ready to continue.
You can also try a 3-on-1 fight against your friends on the beach if you talk to Tidus. It's a little tricky, but rewarding in terms of experience.
The enemy Heartless you meet here are the first in the game that can really hurt you. When you start attacking them you will notice that your wooden sword has no effect on them! Run away from them for now and look around the beach. A strange door has appeared where the Secret Place was before, and Sora can't open it. Go over to the bridge to the small island, where Riku is standing. You will now receive the Keyblade, and it works very well against your enemies.
Fight your way back through to the door at the secret place, and take the opportunity to gain some experience. Now that you have the Keyblade, the door will open.
 Boss: Darkside
- HP: 300
- EXP: 60
It's the same from when you faced it before, but this time, the Darkside has a new attack. It sticks it hand in the island, creating a shockwave. Then it takes out a ball of gravity/darkness and releases it into the air. Now smaller versions of the ball will rain on you from time to time in this battle, but still whack it with your Keyblade and don't forget to hit its head for extra points.
The void eventually sucks Sora up and you leave Destiny Islands!
