A SubTrope of GeographicFlexibility, when writing a small town setting for long enough, you start introducing [[RememberTheNewGuy new characters everyone apparently knows, but has never mentioned before]]. In PoliceProcedural and medical shows, new neighbours are handy for RippedFromTheHeadlines and SubcultureOfTheWeek plots.

Can be a feature of a QuirkyTown. If the city was larger, it'd be a CityOfAdventure. See also TwentyFourHourPartyPeople, LongLostUncleAesop, and RememberTheNewGuy.

Compare/contrast MobiusNeighbourhood, where the main characters only seem to have ''one'' set of next-door neighbours.

!!Examples:

[[folder: Comic Books ]]

* ''SamAndMax''
** Averted in the videogames though; Bosco, Stinky and Sal are neighbours of Sam and Max who are mentioned long before their on-screen introductions.

[[/folder]]

[[folder: Literature ]]

* This happens in the ''Mary Minor, Mrs. Murphy and Tee Tucker'' mystery series written by Rita Mae Brown. The series is set in a small town in Virginia and there are always at least a few new characters introduced with each novel.
* {{R L Stine}}'s ''Ghosts of Fear Street'' series. It must be one long street...
** Some characters don't live on Fear Street, but if they don't, they do something that ''involves'' Fear Street or the also-cursed forest and lake beside it.

[[folder: Live Action TV ]]

* Early seasons of ''{{Smallville}}'' had a new meteor rock freak every week.
* ''Series/{{Everwood}}'', including the flavor of the week patients.
* British police show ''{{Heartbeat}}'' takes place in a small town of Ashfordly, which seems to have a ready supply of people committing various crimes, and in later seasons [[WriterOnBoard suffering from alcoholism and needing]] AnAesop.
* ''MurderSheWrote'', complete with one of the new characters dying in the episode they are introduced. Seems like Cabot Cove is the murder capital of the east coast.
** They poked at the edges of the trope; there were a number of recurring Cabet Covers beyond Jess, Doc Hazlett and the sheriff, and even two episodes where one of these recurrers was the murderer, which the GenreSavvy know isn't supposed to happen.
* Cardale in ''Series/PeakPractice'', another medical show example. Possibly lampshaded in one episode:
-->"Who'd have thought we had a world class jazz musician in our town?"
* The characters of Kate and her family in ''Series/RobinHood'' have apparently lived in Locksley all their lives, even though it's a reasonably small village and they've never been seen or referenced before Season Three.
* The "small town" of ''{{Eureka}}'' keeps adding new characters to the point where Carter, who's been there approximately five years by now, still doesn't know everyone (or even, apparently, most people).
* ''MidsomerMurders'' takes an entire county of small towns as its setting, but it's been running so long that this is a problem anyway.
** Justified, as nearly every episode has 3 or more deaths and without new neighbours, there would be hardly anyone left.
* ''Series/BuffyTheVampireSlayer'' and related media. Handwaved in that the Hellmouth the town is on attracts the monsters and scaries.
* ''Series/StarTrekTheNextGeneration'' did this a few times, most notably in the episode "Lower Decks" which introduced a set of brand-new Starfleet officer characters ... only for them to never be seen nor referenced again. One of these one-off characters is shown to be Ten-Forward's secondary bartender (in lieu of Guinan) who is well-known enough to be a confidante, but had never been referenced before or since.
* ''Series/LittleHouseOnThePrairie'' did this a lot, most noticeable during the first season with students. An episode would center around a student who couldn't read or was disabled or whatever lesson of the week required. Every other child would know who they were and what their problem was, as if that student had always been there. Yet, we'd never seen them before and never saw them since.
** Averted in some early episodes when a few of the school children played by regular extras were slowly given the odd line, a name and once or twice worked into the plot directly for an episode.

[[/folder]]

[[folder: Video Games ]]

* In the first few days of playing ''AnimalCrossing'', a new neighbor moves in every day.
* ''VideoGame/{{WarioWare}}'' series. Not explicitly stated how big Diamond City is as a place, but each game adds new characters apparently just living a few houses away from each other that have never been seen before in the entire series.
* Arguably TheSims, in particularly The Sims 2 and 3 if you're following the stories of the Maxis/EA premade families.
* The ''VideoGame/RealityOnTheNorm'' SharedUniverse is set in a city which seems to gain more and more citizens with each installment.

[[/folder]]

[[folder: Western Animation ]]

* [[WesternAnimation/TheSimpsons Springfield]] started out this way, until all the side characters were cemented as a part of the LoadsAndLoadsOfCharacters cast.
** Also, neighbors of the Simpsons (aside from the Flanders) occasionally appear at random, then disappear, never to be mentioned again.
*** Although this too has settled down a little. Flanders lives on one side, Laura Powers lived on the other side (until that house was bought by [[spoiler:Sideshow Bob wearing someone else's face]], with a brief mention of Powers leaving). More distant neighbors are seldom specified, although Mrs Glick seems to live on the same street somewhere and the house across the road was once owned by George Bush Senior and then by Gerald Ford.
*** That huge house opposite the Simpsons certainly seems to pop out of nowhere.
** Poochy from Itchy and Scratchy can count.
* ''{{Fillmore}}'' reuses the faces of previous episodes' characters, but they never speak or do anything of importance. Outside the safety patrol itself, no character features in more than one episode, [[RememberTheNewGuy even those who have a history with the regulars]].
