Smashville is a stage in Super Smash Bros. Brawl based on Wild World. It is set hovering over an Animal Crossing town, complete with various features of a Wild World town. The time of day the fight takes place in is reflected by the Wii's internal clock, meaning that the sky will be blue at noon, orange in the evening, and starry at night. Some Animal Crossing characters feature as spectators, watching and reacting to the current brawl. Notable spectators include Brewster with a coffee bar, Gracie with her car, and Blathers, who is always asleep during the day. K.K. Slider also makes an appearance to play one of the six songs included every Saturday from 8:00 P.M. - 11:59 P.M., drawing the attention of the spectators. A small, red balloon will sometimes fly across the stage carrying a piece of food, releasing the food when popped, like in the Animal Crossing series, except the food has replaced the presents. Various things from the games can also be seen in the background, like constellations, Kapp'n's taxi, and UFOs.

It returns as an unlockable stage in Super Smash Bros for Wii U, in which it's based on a generic City Folk town. New spectators include Katrina and Phineas, both of which can be seen in the background of the city half of the stage sometimes.
