Begin by talking to Edgar. Edgar is located somewhere on the coast under the lighthouse on the northwest crossbone. He will be near some ships wreck debris. He tells you that his friend is lost, and he asks you to go to Stinky Breeches, the man in the lighthouse. Stinky Breeches must have you do a favor for him first. He gives you directions to retrieve his cookbook from Prison Isle. Rake here to find his book:
About 4 horse paces above a bridge on Prison Isle, you can see the dock with a telescope from where you stand.
When you have it, bring it back to Stinky Breeches, but he says he wants you to get him some dinner before he helps you. He needs beans and rice from Barrett, the Tail Isle General Store owner (costs $200), spices from Rika on Spice Isle (she needs to be bribed with Jewel-Encrusted Scissors that Stinky gives you before she'll sell you the spices ofr $200), and vegetables from Candide on Eldorado Isle, which also cost $200. Go back to Stinky Breeches when you have all the ingredients. Next, he'll need a pot to cook all of it in. Go to Pillan in Santon on Desert Isle. He will tell you to talk to Augie. Augie can be found wandering around somewhere near Oydessus's hut on the second Sand Isle. Inexchange for a pot, Augie tells you he needs shelterf rom the sun. To get the palm fronds for him, head to the oasis in Skull Forest on Pirate Isle. Use your rake southeast (edit: I found them north - tuki) of it and you'll find a Handful of Palm Fronds! Bring them to Augie and get Stinky's pot. Bring the pot to Stinky, and he'll finally help you. He tells you that Edgar's friend is near shipwreck debris on Polar Isle. Go back to Edgar and tell him Stinky spotted him. Rake here to find the friend:
In a bit of debris east of the docks.
Bring him back to Edgar, and receive your reward.
