->''"You boys have had your fun -- '''NOW PAY FOR IT!'''"''
-->-- '''The Coachman''', ''Disney/{{Pinocchio}}''

This would be an event or activity that is presented to one or all of the protagonists as being extremely enjoyable. This event or activity never has any redeeming social value; it's just for fun. It's usually presented as being completely innocuous and not at all objectionable - except, of course, in those cases where the basic selling point of the "fun" thing is that it's something the "unhip, uncool" people of the world would never allow one to do. After perhaps some initial reluctance, the protagonists decide to give it a shot. Bonus points are awarded if some "nerdy" character suggests that it's not a good idea, and [[TheComplainerIsAlwaysWrong everyone either ignores or laughs at this person]].

When the protagonists finally get involved in the alleged fun, it turns out to be either entertaining beyond their wildest dreams or... well, rather boring. In any case, it certainly doesn't seem to be harmful. But that all changes as the story progresses. Maybe the idea of "fun" being offered up goes way over the line, ultimately breaching the frontiers of good taste or sanity. Maybe the entertainment is actually being used as a cover for some nefarious or destructive purpose. Or maybe the event or activity involves a level of near-suicidal danger that no one could have ever seen coming.

The TropeNamer, of course, is the amusement park in ''Disney/{{Pinocchio}}'' that causes boys to turn into donkeys. (For a time at [[Ride/DisneyThemeParks Walt Disney World]], there was a nighttime entertainment district cheekily named after this place and aimed at adults and local clubgoers, though most of the clubs were family-appropriate.)

Often overlaps with TheGamePlaysYou, AFeteWorseThanDeath, and/or CrapSaccharineWorld. Broader than AmusementParkOfDoom, because it can involve just about anything that is ostensibly entertaining. See also DoNotDoThisCoolThing.


[[folder: Film ]]

* The 1997 thriller ''Film/TheGame''. For his birthday, Nicholas Van Orton (Michael Douglas) gets a unique gift from his brother Conrad (Sean Penn). It's a sign-up sheet for Consumer Recreation Services (CRS), which offers customers the opportunity to play an interactive "game." Unfortunately for Nicholas, the only "playing" that ensues is when a conspiracy of complete strangers spend the whole movie mercilessly playing with his head.
* In the 2001 low-budget film ''Zebra Lounge'', a happily married couple become bored with their relationship and decide to meet up with a pair of "swingers" in the city for a night of choreographed adultery. It is all perfectly innocuous (if naughty) fun....until the swingers start stalking them.
* In ''Film/TeenageMutantNinjaTurtles1990'', The Shredder has created a "pleasure island" to lure misguided teens into his Foot Clan. His warehouse is located on the ficticious Lairdman Island and features rap music, pinball/video games, basketball, dancing, billiards, skateboarding, gambling, graffitiing, and tobacco use. Newcomers to the warehouse are told "Anything you guys want... We got. Anything you wanna' do... Do it." The naive protagonist in this instance is Danny Pennington (Michael Turney).
* In ''Film/{{Hostel}}'' the three protagonists have the chance to spend their holidays in the titular hostel in Eastern Slovakia where they can get any girl they want. As soon as they get there, they start having the time of their lives...until they find out that the hostel is owned by a sadistic crime organization that kidnaps tourists and offers them to rich paying customers - who pay to rape and/or torture them in the most gruesome ways.
* In ''Film/FromDuskTillDawn'' the strip bar Titty Twister is actually owned by some vampires who used it to lure trucker and biker in order to eat'em.
* ''Film/BordelloOfBlood'' centers around a brothel that is run by vampires to lure in men.
* In ''Film/DeadEndDriveIn'', the titular prison camp for unwanted youths lures them in by pretending to be a normal drive-in cinema, and keeps them quiescent with B-movies, junk food, and unofficially sanctioned drug use.


[[folder: Literature ]]

* The Land of Toys from ''Literature/TheAdventuresOfPinocchio''. A big place for fun and lack responsibilities, but you will be transformed into a jackass. Well, it's the base of the {{Trope Namer|s}}.
* Some ''Literature/{{Goosebumps}}'' books, like ''Let's Get Invisible'' and ''The Horror At Camp Jellyjam'', use this trope.
* At the Holiday House in ''Literature/TheThiefOfAlways'' there are four seasons a day, every night is Christmas, and the House grants any wish, all made possible by a man called Mr. Hood. Eventually though, Harvey's curiosity and growing suspicions about the House lead him to discover some unpleasant truths...
* ''Literature/{{Animorphs}}'' has The Sharing, a Scouts-esque club for community service that is actually a front to recruit hosts for the [[PuppeteerParasite Yeerk]] invasion.
* The chocolate factory in ''Literature/CharlieAndTheChocolateFactory'' is arguably a positive version of this trope, in that the kids who get punished in this [[CrapsaccharineWorld magical wonderland of a death trap]] are {{asshole|victim}}s who deserve it anyway. Mind you, this doesn't always make it less disturbing.
* Creator/EdwardGorey 's titular ''The Evil Garden'' seems fine, but then people start dying.


[[folder: Mythology ]]

* OlderThanFeudalism: Circe's island and the island of the Lotophagi from ''Literature/TheOdyssey''.


[[folder: Theatre ]]

* Rhododendron in ''Theatre/TheGoldenApple'' gives this trope even more play than in ''Literature/TheOdyssey'', which it is an homage to. Hector leads Ulysses and his crew on a Big Spree, and Ulysses doesn't notice at first that [[DwindlingParty his companions have dwindled]] each successive time Hector passes around his flask.


[[folder: Video Games ]]

* The Isle o' Smiles in ''VideoGame/DragonQuestVI'', reached by mobile island, containing a bar that ferries those who board it from Aridea. [[spoiler: It is, of course, a trap. The staff are actually demons, leading to Jamirus, second of the Archfiend's lieutenants.]] You end up using it as the dream world's water transport, at which point it doubles as an inn.
* One ''VideoGame/RollerCoasterTycoon'' player decided to create an attraction like this in his park. The result: [[http://knowyourmeme.com/memes/mr-bones-wild-ride Mr. Bones' Wild Ride]].


[[folder: Western Animation ]]

* Several ''WesternAnimation/SouthPark'' episodes use this.
** "Chinpokomon" is about a BlandNameProduct version of ''Franchise/{{Pokemon}}'' that turns out to be an UsefulNotes/{{Imperial Japan}}ese indoctrination tool.
** "South Park is Gay" reveals that the [[CampStraight metrosexual]] subculture was started by evil crab people to turn all men into effeminate sissies and make taking over the world easier.
** "Die, Hippie, Die." A large contingent of hippies arrives in town from Colorado's big cities for a massive 1960s-style music festival; they claim that the purpose of the festival is to stick it to all the corporate bigwigs and other "little Eichmanns" who supposedly run America. Stan, Kyle, and Kenny naively join in the "fun" at first, donning their best "student protester" outfits and learning to play the guitar. But as the festival drags on they start to become bored, and they realize the message of social activism preached by the college kids is, well, pretty much b.s. And on top of it all, all the marijuana smoke is starting to make them sick. They try to leave, but the crowds have become much too thick... until Cartman manages to disperse the crowd with the aid of a: [[DrillTank the Hippie Digger]] and B: a disc full of Music/{{Slayer}} tracks (as he said, "hippies can't stand death metal").
** "You Have 0 Friends" portrays Facebook this way when Stan gets sucked into a ''Film/{{Tron}}''-esque digital world and has to fight the embodiment of his own Facebook profile.
* The TropeNamer location in ''Disney/{{Pinocchio}}'' features such pleasures as drinking, smoking, property destruction, and playing pool. Indulging in these activities long enough cause the boys to [[BalefulPolymorph turn into donkeys]].
* The ''WesternAnimation/AdventureTime'' episode "Dungeon Train" features a constantly-moving ring-shaped train that tempts adventurers into boarding it. They are lured into constantly fighting monster after monster in the endless succession of carriages for an endless supply of loot trinkets, until they become a "boss" monster and eventually get killed by one of their successors.

[[folder: Real Life ]]

* Drug use and other addictive behaviors. [[TVTropesWillRuinYourLife Including this very wiki.]]
* Pregnancy and sexually transmitted infections can turn sex into this.
