The Legend of Zelda: Ocarina of Time
Malon, Talon, and Ingo work at Lon Lon Ranch in Hyrule Field. Link first meets her in Hyrule Castle Town, where she tells him that her father has gone missing while delivering Lon Lon Milk to Hyrule Castle. He is given the Weird Egg, which hatches into a Cucco. Link eventually finds Malon's father sleeping near Hyrule Castle. He wakes him up with the newborn Cucco. Fearing Malon's rage, Talon flees back to the ranch to apologize. Malon can later teach Link "Epona's Song" on the Ocarina. When he plays this, the usually shy horse Epona rushes to Link.
Later, when Link returns after having been sealed inside the Temple of Time for seven years, he discovers that the ranch has been taken over by Ingo, and Malon is being forced to work at the ranch, lest Ingo punish the horses. Link eventually beats Ingo in a horse race, and he returns to "normal". Talon moves back to the ranch. After this, Link can participate in a horse race hurdle mini-game. The high score is held by Malon. If he breaks the record, he will be given a cow as a reward. Malon, as an adult, is later seen singing at Lon Lon Ranch during the celebration that occurs during the end credits.
The Legend of Zelda: Oracle of Seasons
Malon and Talon breed Cuccos north of Horon Village, near Eyeglass Lake. When Link first meets her, Talon has embarked on a hiking trip on Mt. Cucco, leaving Malon behind to tend to the Cuccos alone. She acknowledges that she has very little experience with the subject. Link can give her a Cuccodex, an encyclopedia of Cuccos, in exchange for an Egg, which she refers to as a popular "beauty aid" among young girls in Holodrum. This is part of the trading quest for the Noble Sword.
The Legend of Zelda: Four Swords Adventures
Malon can be found in The Field, the first stage of Near the Fields, the game's fourth level. When she is returning to her father's ranch, the nearby Hyrulean Soldiers start firing old cannons, blocking Malon's way with fireballs. Link agrees to help her home and leads her back to the ranch. Talon, her father, then allows Link to use their horses as a reward for protecting his daughter.
The Legend of Zelda: The Minish Cap
Malon and Talon appear again in The Minish Cap. Here, Lon Lon Ranch is located east of Hyrule Town. At one point, Talon manages to lose the key to their house. Link eventually retrieves it for them, allowing Malon to sell Lon Lon Milk in Hyrule Town.
