Favor

Favors are requests from villagers. They might ask for a shirt, a fossil (a specific fossil or just one in general), a bug, a fish, or a piece of furniture. Depending on their personality, they can also ask the player to deliver presents and letters.

An option will appear when talking to a villager, that says something along the lines of "Need help?" or "Can I have a job?" The villager will often have something for the player to do, but may also have nothing, which means the player may have to talk to him or her later to get one from that particular villlager. Villagers will usually ask the player to get a Pikachu doll or Game Boy from one of the villagers. The villager in question may have let another villager borrow it, making things more difficult. Other jobs might be giving clothes or furniture to another villager, finding a ball, or other such tasks.

Sometimes a villager will ask the player to deliver a present or a letter to another villager, but if the player's pockets or letter slot is full this favor cannot be done. If the present is opened or the letter is read before it's delivered to the villager, the villager might ask why it wasn't wrapped. Most of the time these favors will have a time limit, some short like 10 minutes or some a long distance of time like before midnight. Other times villagers will ask for things like clothing and fossils. Snooty villagers may ask for furniture or fish, because it's in style. Saharah, the carpet salescamel, may ask the player to deliver carpets to Tom Nook, Pelly, Phyllis, Blathers, Mable, or a random villager.
