Hey, wait a minute! We seem to have made a wrong turn at Albu-coiky! Now we're in Toon Town, that very special district of Fantasy Land where cartoon characters are people, just like you and me. Sometimes, they exist as a separate and independent species, and sometimes, the place itself transforms humans into Toons. But all details aside, Toon Town is a loony sort of place where Cartoon Physics and the Rule of Funny reign supreme. Expect the Roger Rabbit Effect almost every time.
When an entire planet or dimension is populated by cartoon characters, it is an Alternate Tooniverse.
- Family: The Disney version of Toontown is where the Warners were born and raised.
- In Those Lacking Spines, Inept Crossings seems to serve as the home of the many characters who get lumped into bad fanfiction crossover pieces. Appropriately enough, the Trope Namer itself appears as part of this world, and is suffering under the tyranny of Homie X Luxory and Secks.
- Later, Traitor: Dogen's mind — Dogen's Saturday Morning Kaboom — is a cartoonish world set within a malfunctioning TV.
- The Trope Namer from Who Framed Roger Rabbit, a suburban Los Angeles district where the Toon community lives. Quite crapsaccharine.
- Looney Tunes: Back in Action: Unlike Space Jam and Who Framed Roger Rabbit, the cartoon characters appear to just exist on Earth without much if any inter-world travel, though some speculate that all three movies are in fact in the same universe.
- Last Action Hero: In Jack Slater's movie world, cartoons mix with human beings in the police station.
- In Son of Zorn Earth is otherwise normal but all the cartoon fantasy characters come from the magic island of Zephyria.
- The official mythos of the Disney Theme Parks states that the costumed characters are the real characters. Then there's Mickey's Toontown and Roger Rabbit's Car Toon Spin.
- Inside the parks, Mickey's Toontown at Disneyland is considered where Mickey and co. actually live. You can walk through Mickey's house, etc. (And presumably that's where he retires to when the park closes down for the night.) Walt Disney World had a similar area for many years, and to avoid a Continuity Snarl it was technically labeled Mickey's Toontown Fair - sort of a country getaway for the classic Disney characters. Mickey's pad was billed as Mickey's Country House since, you know, his actual house is in Disneyland. (Mickey's Toontown Fair has since been ceased to exist and absorbed as part of the New Fantasyland expansion.) The smaller Toon Studio area at EuroDisney is presented as the place toons go to work and film their movies. There's also a Toontown in Tokyo Disneyland that's identical to the one in Calfornia's Disneyland but try not to think too hard about that.
- Toon Lagoon in Universal Studios' Islands of Adventure can be seen as an example of this.
- Odds are your friendly neighborhood Six Flags park will have a "Looney Tunes Town" or some variant of it.
- Cartoon Land, from the very early Walt Disney shorts, Alice in Cartoon Land.
- Bonkers was a cartoon, but some people in the cartoon were humans and some were toons. An unusual example where the humans are also animated, just more realistically (they're painted in a shade darker than "Toon" people and objects, have a much more subdued range of motion and especially reactions, and are drawn with five fingers).
- In Sponge Bob Squarepants, the undersea world is animated and the surface world is live-action. This is shown occasionally in the TV show, and more clearly in The SpongeBob SquarePants Movie and The SpongeBob Movie: Sponge out of Water.
- The city of Elmore in The Amazing World of Gumball, a place where Everything Talks and can also become a Funny Animal, is often implied to be a unique location on an otherwise mundane Earth: Citizens of Elmore are shown with various forms of animation, the geography of Elmore consists of real life photographs, and in-universe media often shows humans in live-action, something never shown in Elmore itself. The series's creator even cites Who Framed Roger Rabbit as an influence for the show's use of Medium Blending, liking the idea of cartoon characters being in real life. Other episodes blatantly contradict this, making mention of anthropomorphic non-humans being from places far outside of Elmore. Either way, Rob is the only who knows that they're fictional, and no one thinks of themselves as cartoons (even if they do know they're two or three-dimensional).
- The town that Mickey and the gang live in Mickey Mouse Works and House of Mouse is implicitly Disneyland's Toontown, with Mickey, Minnie and Donald's houses being the ones seen in the park. Goofy's is different because of Rule of Funny.
