Fetch Requests in Harvest Moon: One World

There are two types of requests in Harvest Moon: One World: those that you receive when talking to a person, and those that are mailed to your farmhouse.

Talking Requests will being after you talk to a person and they mention they want to do something, but lack the resources to carry out their plan. These types of requests will come about after you solve the town problems and collect the sprite medallions. You won't typically know that the person has a series of tasks until you interact with the villager, as the game doesn't indicate whether someone is waiting for you to talk to them.
Mailbox Delivery Requests are sent to your farm house mailbox. Each person in the game who can send these repeating request will send you one request and won't send another until after you complete their original task. Everyone has several rotating requests.

All the received requests will be listed in the To Do/Requests section of the Doc Pad. Requests that you haven't completed yet will be listed first, followed by mailbox tasks that are repeats; these are marked with a green checkmarks. Finished tasks will be listed last in the Doc Pad, which have gray checkmarks on them. While you can view the details of an in-progress task, completed tasks cannot be opened.

Press the Action button when the hand cursor is on a request title to see the task details. You'll see the name of the person, the item they are requesting, and the reward you will receive.

While the marriage candidates are always out and about somewhere in their towns, the other villagers are only available at certain times of the day. This makes it tricky to turn in items when you don't know when (or where) the requestee will be around.

If you need help locating the requestee, select the Confirm button at the bottom of the details page to have a red location marker noted on the mini-map when the request giver is available. The red marker does not appear on the larger World Map within the Doc Pad.

Mailbox Delivery Requests

You can receive one mailbox request in the morning when you wake up. The request you receive is determined when you start the day. If you saved your game the night before going to bed, you can reload your save game to go back to bed and see if you get a different mailbox request in the morning.

Tasks sent to your mailbox can be from the main characters or specific villagers. Each has three types of requests they can send you. When you finish a task, the person can send you another one in the mail. The task you receive is random from the three available, so use the save/reload trick if you are trying to get a specific task reward.

The cooking recipes you learn from Holokai and Laura will be added to your cookbook the first time you complete their tasks. They'll still send you the same task that gives the same recipe reward, but you won't learn anything new for completing the task.
