Based on whether there is a special event going on, she may wear different shirts. For example, she will wear a flowery shirt during the Fireworks Show, a bunny shirt during Tsukimi, and a Santa-style shirt on Toy Day. Sometimes if the player talks to her while she's visiting the campground in the Welcome amiibo update, she'll reveal she's actually nearsighted, hence why she wears glasses with her casual outfit. If the player sets their birthday to December 20th in New Leaf, Isabelle will comment on how she has the same birthday as the player.On the Valentine's day event in New Leaf, she appears embarrassed in the introductory segment and sends them a chocolate cake. This may be because of her shyness, or a crush on the player which is debatable because the letter sent to the player is about gratitude.

Items for one time wear or indoor use like shoe covers, boots tops, costume shoes, etccan not be returned. In one of a series of English lesson video featuring Isabelle shown in Japan, Isabelle states that she enjoys whiskey while defining the difference between "whisky" and "whiskey". [13] Isabelle had made appearance in many of the previous Garden Events. She is also the subject of the Off-Hours Café Set.Isabelle is a nearsighted bright yellow dog who resembles a Shih Tzu (this is similar to her Japanese name - Shizue). Her head is also shaped similarly to a bag of bells (hence, the pun on her English name - "Is-a-belle"), meaning "is a bell". She has a happy appearance with rosy cheeks, and white fur patches on her tail and around her mouth. In New Leaf, Isabelle mentions that she still has cardboard boxes littered among her room, and is embarrassed to let Digby see. Isabelle in general may be a somewhat messy person, as Digby, who claims to be a neat freak, notes that while she is not too messy, it is enough to get on his nerves.

Sometimes, if the player talks to her while visiting another town in New Leaf, she will tell the player that she has many sisters who look exactly like her. They all work as secretaries in other towns, and all of them are also named "Isabelle". For her, the town she works in is like a family, she knows the ins and outs of it, and has enough influence to make a villager stop undesirable behavior - such as making them change their clothes or stop them from saying an unwanted catchphrase. Otherwise, she seems to prefer to not want to confront them.
