Toontown is the hometown of Mickey Mouse, his friends, and his supporting cast in most of their animated appearances. It has appeared in various media starring Mickey and his friends including television, films, video games, and a wide array of promotional material (except most comics, which retain the concept of Mickey, Minnie Mouse, Pluto and Goofy living in Mouseton, and Donald Duck and Daisy Duck residing in Duckburg). This town is probably located in the state of California.
Toontown appeared as the primary setting in Mickey Mouse Works and House of Mouse. The town's name was rarely mentioned in either show; it was referred to as such by Clarabelle Cow in the House of Mouse episode "Clarabelle's Big Secret". The name was also mentioned in the text description for the show's online game "Who's in the House?" The city's appearance is based on the Disneyland section Mickey's Toontown, which itself is inspired by Toontown from Who Framed Roger Rabbit. The homes of the town (such as Mickey's red and yellow house, and Minnie's purple and pink house) are directly modeled after the real-life attractions in Disneyland.
As mentioned, the town serves as the home for Mickey Mouse and friends, though in both Mickey Mouse Works and especially House of Mouse, several characters from the Disney animated features canon have made appearances around Toontown, mainly at the town's nightclub on Main Street, the House of Mouse.
Donald's House - The residence of Donald Duck. In some depictions, Donald's house appears as an average house, while in some other appearances such as Mickey Mouse Works, it is a large boat modeled after the Miss Daisy from the Disney theme parks.
Goofy's House - The home of Goofy. As with Donald, Goofy's house takes on a number of different appearances, including an average home, a trailer in Mickey Mouse Works, or a large, sloppily-built home with a stone chimney, as featured in the theme parks.
Ludwig Von Drake's Laboratory - The home of Ludwig Von Drake. In Mickey Mouse Works, he generally spends his time in his large basement, using the space to create and test numerous inventions.
Pete's House and Hideout - The residence of Pete, of which he has two: a regular one and, as seen in Mickey Mouse Works, a none-too-subtle hideout where he generally holds Minnie captive, threatening her life with various traps, as Mickey breaks in and battles Pete's traps to save her. This second residence is also the setting for the final race in Mickey's Racing Adventure.
Commercial bumpers featuring a Toontown-based appearance were used on Toon Disney from its launch on April 18, 1998, through September 1, 2002.
This town-based area (similar to the city settings of House of Mouse and Teamo Supremo) was also featured in the bumpers from international version of Toon Disney from March 15, 2003, to October 2011, as well as the Scandinavian version of the channel had a cardboard-created city that used in 2008 to 2009.
