- See here for an incomplete list of letters.
"It's the start of softball season! I accidentally hit (random villager) with the ball when I was pitching. Oops. (villager gender) was really mad! ♥ Mom."In all four Animal Crossing series games, the player will frequently receive in-game letters from Mom, purportedly the character's mother. Letters from Mom usually contain a small anecdote about life in the character's home prior to moving into the town; these anecdotes usually concern certain memories of the player that she has, a tale relating to "Dad", or some words of wisdom or guidance.
— Mom, Wild World
Mom will also occasionally send gifts in the mail, on the player's birthday, Toy Day, and on New Year's Day. Mom also sends Bells, non-native fruit, acorns, and mushrooms in the mail. Mom is never actually seen, nor is it known how/why the player came to move away from home in the first place. Outside of the letters, the player's mother is never brought up in conversation by any of the animals. It is also not possible to send letters back to Mom.
Mom will give the player a pink carnation on Mother's Day.
- In Animal Forest e+, Mom will send the player a letter talking about a Bean Throwing Festival on February 3rd. Later, on July 7th, she will tell the player about the Festival of the Weaver.
- In New Leaf, Mom will send the player a gift congratulating them on becoming mayor of the town.
Dad is the father of the player in Animal Crossing series. He writes only on Father's Day, usually saying something like "See? Your Mom isn't the only writer in the family". Like Mom, he can't be seen and is merely a tiny part of the player's current life. In City Folk and New Leaf, he gives the player a red carnation during Father's Day and that is the only way to obtain the special flower. He is never mentioned in the game except during those times. In New Leaf, he will write a bit more often, sometimes including random furniture or stationery. Unlike the mother of the player, he will not send clothing.
