Cookie (ペリーヌ Perīnu?, Perine) is a peppy dog villager in the Animal Crossing series. She was absent from Animal Crossing: Wild World, but returns in Animal Crossing: City Folk. Cookie is so called because of her cute appearance or because treats for dogs are sometimes called cookies. Her initial catchphrase, "arfer", is a variation of the word "arf", the sound a dog makes.
Cookie is a pink dog with a white stripe that starts from the top of her head and goes down to encircle her muzzle. Her eyes are somewhat anime-styled and her paws and tail tip are white. Cookie's brown nose resembles a chocolate chip, hence her name Cookie. She has a brown smile and her ears are a darker shade of pink than her body. Initially she wears a Blue Tartan shirt.
As a peppy villager, Cookie will always appear to be in a good mood. She will get along with other villagers, including the player. She will enjoy the usual hobbies and may ask the player for bugs or fish that she finds cute. Cookie gets upset easily, but due to a short attention span, she will just as easily forget ever having the conversation. Like all peppy villagers, she dreams of becoming famous in the future. She will get on well with normal, lazy, jock, and other peppy villagers, but may annoy snooty and cranky villagers with her upbeat, cheery personality. Cookie loves fossils and clothes and will ask for them often.
Cookie's house is country-themed, with a large collection of Ranch Furniture, such as a Ranch Hutch, a Ranch Bed, a Ranch Wardrobe, a Ranch Armchair, a Ranch Chair, a Ranch Tea Table, a Ranch Table, and even a Ranch Dresser. K.K. Chorale plays on her Hi-Fi Stereo with her whole set of Tootoids. In Animal Crossing, she plays K.K. Country on her stereo instead of K.K. Chorale. Her Wallpaper is the Ranch Wall and her Flooring is the Ranch Flooring. In Animal Crossing: New Leaf, she has DJ K.K. playing in her house.
- Pendleton Ward, the creator of Adventure Time, hates Cookie; he has publicly expressed his distaste by placing many pitfalls outside of her home, among other methods.  Oddly, in this recap, Cookie is mistaken as a male, like a lazy villager. In his town, Smelly, Cookie's catchphrase is "slap me", because he hates her so much.
