Where to find the items for the raft on the island in kingdom hearts

Nearby where you first talk to Kairi is a boulder blocking a small cave. Push the boulder aside to find the Mushroom. Next, attack any coconut trees on the island (it really doesn't matter which) and claim two Coconuts. Nearby where you race Riku will be a large wooden tower. In the bushes will be another Mushroom. Fill the empty canteen up with Water from the natural spring or the small waterfall on the other side of the island. Swim in the ocean near Selphie to catch three small Fish. Next, talk to Wakka and he'll tell you about the Secret Place. Enter the Secret Place and get the last Mushroom. The last item you'll need is the Seagull Egg. Hop onto the shack nearby Wakka and walk to the nearest palm tree. You'll be able to see the egg on top. Climb up the skinnier palm next to it and aim so the egg is directly behind Sora. Jump off and hold down on the left analog to get the Seagull Egg.
