Dotty is a black and white Dutch Rabbit with tall ears that are turquoise inside. She has a smile by default along with round eyes that go red when she is surprised or shocked. Her paws are white (known as "white socks") while her arms are black. Her stomach and legs are nearly white, with grey marks on her legs. She initially wears a Blue Check Shirt in every game prior to New Horizons, where her outfit changes to a blue Sleeveless Tunic.
Below is a brief description of the peppy personality. For more information, click here.
Peppy villagers appear to be in a good mood often and are easy to become friends with. As a peppy villager, Dotty will have the tendency to over-react in conversations about trivial subjects, and will usually be over-excited to see the player or other villagers. This villager, like other peppy villagers, will rarely be discouraged from doing anything, including the usual hobbies. Peppy villagers dream of becoming famous in the future and read Ms. Nintendique, an unseen magazine read by snooty, normal, and other peppy villagers in the Animal Crossing Series. Peppy villagers will also have a very short attention span, which means they soon forget some arguments or tasks given to the player which weren't completed. Dotty may easily get upset in conversation when the wrong things are said. She will get along well with other villagers, particularly lazy, normal, jock, sisterly and other peppy villagers, but she may annoy and upset cranky and snooty villagers, whose personalities differ to hers. Due to the nature of peppy villagers, she may mention how "old" or "boring" cranky villagers are compared to her opposing, upbeat personality.
From Animal Crossing to Animal Forest e+, her house has the Tropical Vista (wall) and Tropical Floor. The Moai statues decorate the center of the house and in the corners, she has a toilet and alarm clock. Her Tape Deck will play Aloha K.K., giving off a Hawaiian theme.
In Wild World and City Folk, Dotty's house has a Space Theme, but also includes the Desert Vista (wall) and Saharah's Desert (floor). Her decor consists of three Spaceman Sams, a Lunar Rover, a mochi pestle, and a Space Station. She listens to K.K. Technopop on her stereo and has one gyroid - the Tall Sproid.
In New Leaf, Dotty's house contains a mixmatch of modern and glossy, with furniture such as the Modern Bed and a couple of pieces from the Sleek Series, such as the table that has a stereo on top that plays K.K. Technopop, lamp, and the side table. Other furniture pieces include the Shower Stall, a Pachira, Cream Sofa, a dresser, and a concert light. She has the Stripe Wall and the Sleek Carpet as her choice of flooring and wallpaper.
In New Horizons, Dotty's house has more of a natural feel to it than her modern and sleek room in New Leaf, with an abundance of green and wooden furniture. In the upper right corner of her room is a green Wooden simple bed with a Floral swag hanging on the wall above it. Next to her bed is a Wooden end table holding a Portable record player, which now plays her new favorite song, Drivin'. Centered along the back wall is an oak Ironwood clock, and to the right of it sits her Wooden wardrobe and full-length mirror. The middle area of the room contains a Wooden low table with a Tea set on top, and a green Yucca. Next to the doorway is a Floor Lamp, and to the right is a mini kitchen area with a Mini-fridge, Gas range, Toaster, and Simple kettle. She has the Green Intricate Wall and Pine-Board flooring.
Dotty and Ellie share the same catchphrase in Animal Crossing. When Ellie returned in the Welcome amiibo update, her catchphrase was changed.
When Dotty is surprised or angry, her eyes will turn red. She shares this trait with Aurora.
The reason Dotty's house follows a space theme in Animal Forest may be due to the folklore surrounding the idea of a rabbit that lives on the moon pounding in a mortar and pestle, a myth that predominantly exists in East Asia.
