The Farway Museum is an unseen museum in Animal Crossing and Doubutsu no Mori e+.

Mt. [Town name]
Posy Farm is an unseen farm that supplies Tom Nook's Store with flower seeds.

It will thank the player for purchasing Posy Farm seeds and will have a silver can attached to it.
Sumware is an unseen location in Animal Crossing: City Folk. The name Sumware is an intentional misspelling of "Somewhere", to make it appear to be a real place. Mabel claims it is where Wendell lives, after moving from Tuskany.
Tony's Dancing Clown Coffee
Tony's Dancing Clown Coffee is a café mentioned by snooty villagers in Animal Crossing: New Leaf when they are talking about gimmicks in cafés. While they are discussing the topic, Brewster mentions offering brunch, causing the villager to get upset. As a result, Brewster cancels the plan to offer brunch.
Treehut is an unseen town in Animal Crossing: Wild World and Animal Crossing: City Folk. When the player first goes to Able Sisters, all the designs that initially are there are from people that reside in Treehut. Sometimes villagers, usually when talking about clothes, mention Treehut or an inhabitant of Treehut, usually mentioning how ahead of style Treehut is. Treehut may be the first town created in the first demo tested by the creation team, though this has not been proven.
Tuskany is an unseen town in the Animal Crossing series, the home of Wendell in Animal Crossing: Wild World. In Animal Crossing: City Folk, however, Mabel states that Wendell is from Sumware. The name Tuskany is a pun on the word "tusk" and Tuscany, Italy.
