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.

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 are initially displayed are created by 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 is named after Nintendo Treehouse, Nintendo of America's localization team, and the authors for the default designs are members of the team.
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.
