From Nookipedia, the Animal Crossing wiki
Sable (あさみ, Asami) is a character in the Animal Crossing series, co-owning the Able Sisters tailor shop. She is a shy, reserved character that prefers to work in the background while her younger sister, Mabel, assists customers.
Sable is a brown hedgehog with pink freckles and sad, shy eyes. She has no visible mouth, so instead talks by moving her nose. She wears a pink and white gingham apron and has a head full of large, spiky bristles.
Sable's life is very focused around the world she grew up in- she is happy with the slow pace of the country life and has proven to be firm friends with others from the village, most notably, Tom Nook. When Sable was only a young girl, her parents died, leaving her to care for her younger sister. She reminisces frequently of her parents, often sharing stories of her childhood. It is not known how her mother and father died, but it is certain that Sable was very unprepared, having to mature quickly and sacrifice her own happiness for that of her sister. This lowered her self-confidence and made her the introverted adult she is today. After her parents' death, Sable took over the family business and taught herself to embroider and make clothes.
Sable maintains the same role as in future releases of the game. She can be seen sewing in the corner, keeping quiet and secluded. If the player keeps talking to her she will start becoming their friend and sharing memories to them about her childhood. Sable also has a younger sister Mabel, who helps run the shop.
In Animal Crossing: Wild World, Sable has a very similar role as she did in Animal Crossing. She is never seen walking around the shop, because she is always using her sewing machine. She does not say much unless the player becomes friends with her, but this takes some time to do. Talking to her everyday increases the chances of her revealing information about herself. At first she will say things like "Ummm... who are you?!", but when she is friends with the player she will begin to say things like "Welcome! I'm so glad you decided to pay us a visit..." She watches a soap called Pointed Love, which she will comment on every Thursday. Sable is affected by episodes every so often, but this only happens if the player befriends her.
In City Folk, Sable's role remains unchanged. After the player speaks with Sable every day for six days, she will eventually stop ignoring him or her, but will make comments about the day of the week and sometimes tell him or her stories about her past life and childhood. During the episode she reveals a family secret, stating that the worker in GracieGrace is indeed her younger sister, Labelle. Sable does not get along with her sister, as she feels that Labelle abandoned her to go to the city when their parents died, leaving her alone to look after Mabel. There is also a glitch that allowed a player to be stuck behind Sable during online play.
In New Leaf, Sable is still a seamstress working at the Able Sisters, now located on Main Street. As in previous games, she becomes more chatty if the player speaks to her frequently and she eventually allows the player to use the QR Codes machine.
Sable has a minor role in Dōbutsu no Mori (film). She is seen sewing patterns, like in the games. Also, she is seen sitting in the front row next to Mabel during K.K. Slider's performance. She doesn't say much, but she greets Margie when she comes in with some drawings.
Sable appears as a trophy and will occasionally appear in the background of the Smashville stage.
