The shop takes on many appearances throughout the Animal Crossing series. In the majority of its appearances, it is a predominantly dark colored red-purple tent with green and gold stripes. In Animal Forest, Animal Crossing and Animal Forest e+, Katrina pitches the tent in a random acre in the player's town.
In Wild World and New Leaf, the store retains its appearance as a tent but can be found pitched a fixed position outside the Town Hall (Wild World) or the Town Plaza (New Leaf). In New Leaf, once the player has had their fortune told over 20 times, Katrina will permanently place her store in a building in Main Street.
In Animal Forest, Animal Crossing, and Animal Forest e+
In the early versions of Animal Crossing, the Fortune Shop is randomly placed in the town. The player can talk to Copper, who will give the player the number of the acre it can be found in.
Inside the tent Katrina can be found behind a desk with a crystal ball, tarot cards, Bells and two torches on top of it.
In Wild World
When the player enters the shop, Katrina will welcome them by saying "Welcome back, lost traveler of the (zodiac sign)." She refers to the Zodiac sign from the birth date the player told a villager near the beginning of the game.
In City Folk
In City Folk, Katrina's store is now a permanent building in the city. Katrina's shop will appear ominous: It is a caramel colored building covered in ivy vines, with an image of an all-seeing eye in the window. It is located at the end of the walkway on the right of the City. It is next door to Shampoodle, with an inaccessible building in between them.
Inside, the building takes on a similar appearance as in previous games. There are green draped curtain behind Katrina's desk, a pile of large books and large, opulent white and blue vases.
Katrina charges 100 Bells for a charm of fortune. She does not curse the player or ask for 10,000 Bells to remove any curses. If the player visits the shop at the beginning of their visit to the city, a pot will fall from the ceiling and whack the player on the head, although this does not produce any bad luck after the visit. The player can only visit the shop once a week for a charm or to have their fortune told.
Jock villagers in the city will mention Katrina's shop, saying, "You know that fortune-teller's place by the side of the road? WAY sketchy...Pulling a sick 360 flippie while skiing off a cliff? No sweat. Walking in there? NO WAY," proving the shop to be suspicious to villagers.
In New Leaf
In New Leaf, the Fortune Shop takes on two appearances. Initially, Katrina will set up the shop as a tent in the Plaza, by the Town Tree in the same spot as other visitors' tents. She will charge the player 500 Bells to tell them their fortune and what item of clothing they require to boost their luck.
After the mayor and any other player characters in town have their fortune told by Katrina a cumulative total of 20 times, she will suggest setting up a permanent shop in the empty building on Main Street (next door to the Dream Suite and behind the Photo Booth) as a public work project for 340,000 bells. The player does not have to have their fortune told in their town; they are able to visit another player's town to have their fortune told and it will count towards being able to build her shop on their main street.
Once her shop is built, she can be visited once a day, and can offer the player a Tingle hat or a Red Daikoku (celebration) hat for 10,000 Bells each. When these hats are worn, they will have an effect on the fortune Katrina tells the player.
During a fortune telling, the walls and the floor of the fortune shop will disappear and be replaced by a Zodiac star wheel on the floor and stars in the background. Once the fortune has been told, the floor and the walls return.
