Look in the sky during a perfectly clear night and tap when a shooting star appears to get a special gift the next day.
When animals are saying” I love you, I love you not", always choose "No", "I love you" and "I love you" to get a free item.
Every day, one tree in town will have a random item. Note: If a neighbor is looking at a tree, there's an item in it.
To get free items from other animals, equip your own fishing rod or net and keep talking to them if they are also holding a net or a fishing rod. They will say that it's a beautiful day for fishing or bug catching. Keep talking to them until they say "Why don't we have a competition?". Accept the competition and catch whatever they ask you to catch. When you have caught it, bring it back to the animal and talk to them to get a prize in return. Note: This works more than one time on the same animal.
Send your neighbors letters and attach items you do not want. They will usually send you furniture, clothes, and rare fruits the next day.
