And the tall man answered in a low voice: "On the beach."
It's sometimes said the best place to hide something is in plain sight. But suppose that logic won't work — the object you're trying to hide happens to be something that would stand out no matter where you put it. How do you hide such a thing?
Why, by making about a thousand duplicates and hiding it amongst them! It'll be nigh-impossible for future treasure hunters to figure out which is the right one. They don't have to be exact copies, either: So long as there are too many to go through, the object is completely safe.
This kind of challenge is set up so characters can demonstrate their intellect rather than physical prowess. Figuring out the clue to deduce which is the real MacGuffin may be a Secret Test of Character. Or perhaps a test of lateral thinking - there is often a way to Cut The Knot.
A variation on Hidden in Plain Sight. Doppelgänger Spin is this tactic applied to battle. For hiding people, the equivalents are Lost in a Crowd, I Am Spartacus or the Ringer Ploy. Shell Game is when a stack of needles is made while a witness watches. Pixel Hunt is the video game equivalent. Serial Killings, Specific Target is when the 'needle' that's being hidden is a specific murder amongst what appears to be the work of a serial killer. Decoy Convoy is when the "needle" is hidden in separate transports.
- In Pokémon, Team Rocket does this in order to steal a Togepi egg.
- In another episode, Team Rocket steals numerous people's Pokeballs by claiming that they had a special Pokemon-trading machine when Meowth was actually hiding inside the machine and swapping out the filled Pokeballs that came in with empty ones. When Ash locates the place where they hid all the Pokeballs, he initially can't find his own Pokeballs among the countless identical-looking ones until Pikachu sniffs them out for him.
- "Gotta Catch a What?!" has a whole group of wild Pikachu captured alongside Ash's by Team Rocket. Thing is, aside from knowing the gender difference they barely have any way of telling which Pikachu is the one they're looking for (and the wild Pikachu aren't giving up the answer to Meowth).
- Used by Jasdero and Devit in D.Gray-Man while they were screwing with the exorcists on the Ark. During the initial fight, they dropped the key to the door leading deeper in- so Jasdevi materialized enough keys to cover the entire floor of the room. However, Lavi has a Photographic Memory and eventually picked it out by the patterns of wear.
- This very phrase is uttered by Lust in the dub of Fullmetal Alchemist when she and Gluttony are looking for Dr. Marcoh's notes on how to create a Philosopher's Stone. His notes are in the form of an unidentified book. And the book is written in code so you can't tell just by reading it that it's about the Philosopher's Stone. And it's in the largest library in the entire country. Unfortunately, they soon get into a battle with Scar that results in the entire library being burned down, preventing either of them from accessing the information they need. What they don't know, however, is that Sheska recreates the very book from her own memory. In fact, she recreates the entire burned section of the library!
- In Bleach, for Ichigo's training to learn bankai, he must find his zanpakuto amongst a field of hundreds of other zanpakuto, which shatter immediately if he tries to use them to defend himself against the manifestation of his zanpakuto spirit that is attacking him.

It was a manifestation of him depending too much on Zangetsu.
- In one arc of Detective Conan, a priceless pearl is hidden from a Phantom Thief by giving every guest to a party on a ship a replica. Of course, this being the Kaitou KID, he finds it anyway. He figures out that the pearl's owner has the real thing because he sees her handle it carefully to avoid damaging it.
- And in Code Geass R2, Zero bargains with the Britannians to be exiled instead of executed along with the rest of the Black Knights. Cue every member of the Black Knights and every other Japanese citizen at the assembly dressing up in Zero's trademark outfit. This left the Brittanians stuck between letting them all go, which they ultimately choose, or killing them, which would spark riots and violence all over Japan. Zero was relying upon the fact that he knew the person behind the agreement would do everything in his power to avoid senseless bloodshed - which is good because a lower-ranking member of the Britannian government was fully prepared to start shooting first and identifying corpses later.
- In the Hidamari Sketch manga, after Yuno lost her room key, the replacement key is in a box full of other keys, forcing Yuno to try them one by one to find out which one's the correct key. In the anime, it was the landlady who has to do it.

- In the second Teenage Mutant Ninja Turtles anime, Shredder and his gang are trying to steal a sacred mirror from a clan of Japanese ninja. The mirror ends up on the roof, and to stop Shredder from getting it, the ninja throw out dozens of identical mirrors to confuse him. Just as the ninja are laughing at their cleverness, Shredder asks how they know which mirror is real, causing them to panic. It becomes a moot point anyway, as the evil spirit haunting the mirror just points out the way.
- My Monster Secret spoofs this when Akane steals Mikan's glasses. First, Akane attempts to hide the glasses by throwing out dozens of pairs of glasses. It fails because aside from the other pairs being completely different designs, she's wearing the glasses she stole. Then she tries again, by replicating herself. It fails again because none of the clones are actually wearing the glasses. She gets it right on the third try.
- In the "Kindaichi the Killer" arc of The Kindaichi Casefiles one of the most suspicious things Kindaichi noticed in the first murder scene was a smashed fishtank, and everyone was led to believe that it was destroyed in a struggle between the true killer and his victim, or the killer used the water in the tank to wash away any traces. Both theories are technically half-correct: The killer and his victim had a fight, but it instead caused the killer to accidentally smash his glasses. Since both the victim and Kindaichi aren't wearing glasses, the killer destroyed the tank in order to hide any of his glasses' shards among the rest of the tank's remains.

The duo learns that the man who had it gave it to an African tribal chief, who bored a random rhino's horn, put the microfilm in there, and... released it back to the wild, amongst thousands of other rhinos out there. The eponymous yellow-horned rhinos are results of the duo's attempt to identify which rhinos they had tranq'ed, examined, and marked off.
- Archie Comics had one story where kids from a rival school swipe a noted football jersey that's Riverdale's Good Luck Charm, whereupon Archie and the gang swipe the rival's charm, a lucky coach's hat.

Joker actually had Superman's friends with him on a train heading out of Metropolis; he reasoned that the lead-lined coffins would make finding the coffins difficult for Superman since his x-ray vision wouldn't work on them, but instead the opposite proved to be true; the lead-lined coffins stuck out like sore thumbs. He was able to find Joker and his hostages with ease from there.
- In Requiem Vampire Knight, the main protagonist has to rescue his love interest, who has been forced to become Dracula's bride.

- One early Batman comic had Joker offering his services as a criminal superhero; In exchange for some loot, he would rescue crooks pinned down by the cops during heists. He stashed "Joker signals" at every potential robbery target in Gotham, and even built Joker-versions of Batman's vehicles. In order to get him, Batman discovered the signals and had the cops set off all of them; as a result, Joker couldn't figure out which one had the most loot to take a percentage of. Naturally, the first stop he made had Batman waiting to collar him.
- In Final Fantasy VII fanfic Off the Line, Cloud uses an enchanted necklace that turns him into a woman to hide from bounty hunters and visit a city in peace.

- A possible subtrope in its own right involves a car chase being aborted by having the protagonists parking in a row of parked cars. Jackie Chan's Who Am I? (1998) involves a woman who Drives Like Crazy to pull this off flawlessly, and The Other Guys has Will Ferrell doing this in a row of cars on an elevated platform (he credits Grand Theft Auto for his driving skill).
- In Drive, this trope turns a tense cat-and-mouse getaway chase becomes a Hot Pursuit and The Driver evades the police by driving into the Staples Center just as the crowds rush out of a Clippers game. There are 3,300 parking spaces at Staples and the getaway vehicle is an Impala (one of Chevrolet's most popular models).

Other cases are picked up by Brown and Sally, including one where one of their friends accidentally took a bully's bike, mistaking it for his own. Encyclopedia then imagines being in a court, acting as a lawyer for the friend and eventually asserting that among a bunch of other bikes (though each were different), the bike in question could be mistaken for another. This became his "Eureka!" Moment as to how the boxcar could have been stolen.
Encyclopedia Brown: If you had a needle, where would you hide it?Sally: In a haystack?Encyclopedia: No, with a bunch of other needles. You can't tell which one's real because they all look alike.
- He later invokes it when talking with Sally:
- In Urban Legends: Final Cut, during the big face-off with the serial killer, both the guilty party and the campus cop drop their guns in the struggle.

- There's an Irish folktale in which a poor man catches a leprechaun and demands a pot of gold. The leprechaun tells him it's buried under a particular weed in a field.

- Harry Potter likes this trope:
- In Harry Potter and the Philosopher's Stone, Harry has to find the right key from amongst a group of flying keys.

- At the beginning of Deathly Hallows, the Order has to transport Harry safely from the Dursleys' to the Burrow. They have six Order members take Polyjuice Potion, turning them into exact replicas of Harry, so that when the Death Eaters attack they'll be unable to tell which is the real Harry. The Death Eaters discover him fairly easily; all they had to do was focus their attack on a random replica; they knew from repeated experience that the professionals who volunteered for the scheme are dedicated to the ruse, but the real Harry would Stop to Help.
- Also in Deathly Hallows, one of the Horcruxes is enchanted to create burning hot duplicates of itself every time it's touched. The duplicates themselves are similarly enchanted so that touching the cup sets off a chain reaction that buries the thief alive in burning hot cups. Everything in the room is enchanted to burn and multiply if touched, which makes it all the worse.
- In Nate the Great and the Missing Key, Nate deduces that the key to his friend's house was hidden in a dog's collar, "along with other shiny silver things."

- Similarly, in The Laughing Policeman someone shoots up a bus and kills nine people — all eight passengers and the driver. One of the victims was a detective investigating an old murder (nearing the statute of limitations), and police assume he was the intended target because of that case. They are only half right: The primary target was the suspect in the old case, acquitted on insufficient evidence. The one who killed this time was the one who hired him back then. The murderer later said that he told the victim to take the bus at this precise time so that there'd be a few other passengers to throw the police off.note In addition, the old case being re-investigated is full of false leads, and the detectives find the murderer in the old case files only after the confession.

- This was later referred to in a McGurk mystery novel involving ceramic dogs, with the restriction that McGurk as a Meddling Kid, can't go around smashing the statues, so he has to deduce which one holds the stolen object without breaking it. Knowing that the item was hidden recently, he looked for the statue which still had wet clay on its bottom.
- The Hobbit had this once the dwarves finally get rid of Smaug and begin looking for the Arkenstone. You'd think such a beautifully, stunning gem would be easy to spot but it's buried among all the other countless jewels and trinkets in Smaug's massive hoard. They dig through the pile for days without finding it. This case is actually a subversion, however: Bilbo found it right away, in the dark, and took it before the dwarves had even begun to look.
- Little Brother: The protagonist is careful to keep all of his communication encrypted so that the Government Conspiracy can't keep tabs on him. However, he realizes that if they think to analyze system traffic based on how much of it is encrypted, rather than trying to read the messages, that fact alone is a huge red flag — since most systems only encrypt data that's actually important. He convinces his ISP (he uses a local, independent operation that he works part-time for) to encrypt everyone's traffic so that he and his allies no longer stand out.
- In The Magician King one of the magical keys they're looking for is hidden on a beach entirely composed of thousands of keys. All of the other keys were guarded by either a puzzle or a monster, so they figure there's probably a trick to finding it, but they can't work out what it is so they just spend twenty-four hours a day for a couple weeks trying every key until they get the right one.
- The novel and various film adaptations of The Twelve Chairs are about the search for a fortune in jewelry that was sewn into the cushions of one of a dozen externally identical chairs.
- In one of the Tommy and Tuppence stories, when Tommy and a confederate find the villains' hideout, he marks the door with a cross, referencing The Tinderbox. The confederate is actually one of the gang, and marks the other doors as in the story. Subverted because Tommy already suspected that, and referenced the story to distract him while he dropped a bottle of valarian essence. Tuppence and the police just have to find the door surrounded by cats.
- Subverted in Magic: Top Secret. The protagonist has to search the Egyptian royal palace for a hidden radio transmitter being used to send information to the Nazis. He finds a repair room full of disassembled radio sets and has to waste time searching it because he assumes this trope. However, the radio turns out to be elsewhere.
- Given the two earlier entries above, Agatha Christie really liked this trope. In After the Funeral (or Funerals are Fatal), the Abernethie family gathers after the death of patriarch Richard. Everyone believes that he died of natural causes, but Cora Lansquenet, his eccentric sister, comments offhand that "He was murdered, wasn't he?" The next day, Cora is found murdered herself, and it seems like the killer is on the trail of anyone who knows too much about the plot; various other attacks on family members, plus their own suspicious secrets getting out, lend credence to this theory. Hercule Poirot eventually realizes that the "Cora" at the funeral was actually Mrs. Gilchrist, the real Cora's housekeeper, who planned to murder her employer to get her hands on a rare painting that she'd inadvertently acquired without realizing its value. Richard actually did die naturally—Mrs. Gilchrist assumed the Cora disguise to trick everyone into thinking a murderer was on the loose, with Cora's death glossed over as part of the chain.
- Dragon Steel: Near the end of the book, the heroes break into King Sambars treasury to retrieve Monkeys staff and the magic cauldron they came for, but find that everything is hidden among countless perfect replicas; the only way to identify the real from the fakes is with the guards' Magic Mirror, which only reflects the real one.
- In one William Johnstone western, "Gunsmoke and Gold", the heroes know that the Hidden Villain has a mark in his boots that leave distinctive footprints and set out trying to identify him that way. But then they discover that the mark in those boots is caused by nails sticking out of a commonly used boardwalk (whether that was how the bad guy's boots were marked in the first place or whether he stuck out those nails to make other boots leave tracks like his upon realizing they were onto him is unclear), meaning that half the town has boots with that mark and there's no way to narrow it down.
- The 4400: "The Wrath of Graham" featured a teenage loser named Graham who, after taking a promicin shot, develops the ability to make people worship and obey him like a god. He quickly begins abusing his power and brings his entire school under his thrall, with plans to spread even further. When a few cops show up to take him down, they're told that Graham will be wearing a hoodie... unfortunately, Graham suspects this and has all of the people in his cult wear one. This confuses the officers and gives him enough time to sneak up and steal their free will as well.
- One episode of Agents of S.H.I.E.L.D. starts with a group of guards dressed identically and all wearing red masks while carrying identical briefcases to protect a shipment of diamonds. It doesn't work because the one tracking them has X-Ray Vision, and thus can see which of the needles is the right one to target.
- The Amazing Race is a huge fan of this trope. One notable Road Block involved finding fake pieces of food amongst a huge table of real food. The catch was that if you chose wrong, you had to eat the food you picked. This, obviously, became a huge problem when some teams made several dozen wrong choices...
- Burn Notice featured something similar when Maddie had to hide from some armed thugs. Instead of making Sam drive her to Orlando to hide, she joined up with a senior citizen gambling group, saying something along the lines of "If they can find an old woman here... they deserve to get me." (Thereby freeing up Sam to help Michael.)
- Occurs in the pilot episode of Castle, with a lampshade from Castle about why criminals use this trope.
Alexis Castle: How do you get away with one murder by committing two more?
Richard Castle: At one death, you look for motive. At two, you look for a connection. At three, you look for someone like Kyle. At three, you don't need motive, because mentally unstable serial killers don't usually have one.
- Another episode had a little girl's kidnapper give specific instructions on the backpack the ransom is to be left in. Esposito tackles the first person he sees with said backpack, but it's full of tissue paper. Then they see that almost everyone in the area has one. It turns out the kidnapper had posted online about a flash mob, enticing unwitting strangers to create the needle stack.
- In Community the plan to grift Professor of Grifting De Salvo involves dozens of identical briefcases filled with fake money and one with real money. Disdainful of their grifting abilities, he complains that there's no point to this element, as the real briefcase was just taken away and isn't hidden among the fakes. On the other hand, it did frustrate him further, and due to his class requiring students to buy two $150 "standard-issue grifting briefcases", they did have a lot of identical briefcases filled with fake money already on hand.
- In one episode of Covert Affairs, an operative is killed right before delivering important information to the CIA. They know that he hid the information inside a period on a piece of paper. His cover was a college professor, so his house was full of books and writings. Trope played straight, but Auggie inverts the Stock Phrase, describing it as "like finding a needle in a haystack... in a forest full of haystacks."
- In Criminal Minds, Reid points out that this is a more apt metaphor when looking for an UnSub who they predict will look and behave just like he belongs in the neighborhood.
Reid: A needle would stick out in a haystack.
Morgan: And this guy doesn't stick out.
Reid: Exactly. We're looking for a particular needle in a pile of needles.
- In CSI there was an episode where a murder victim was put inside a body-farm: a place where bodies are put in a number of different positions/environments so people can learn how they decay. It's also subverted as they immediately notice that it's out of place and not on record.
- An episode of CSI: NY had a killer disguised as a clown to perform a murder, and when he fled the scene, it turned out he'd hired a bunch of other clowns to dress up like him and hang out around the scene of the crime.
- Invoked by Sheldon Hawkes in another episode. "We're looking for a needle in a stack of needles."
- In Season 3 of Dexter, after having killed a man in front of Prado, Dexter lies to him, telling him he hid the body a foot underneath the soil...in a freshly-dug grave at a local cemetery.
Prado: Stroke of genius, man...hiding a dead body in a cemetery.
- In Season 4, after the police piece together what the Trinity Killer must look like:
Angel: So, we're looking for an old, retired, white guy...in Miami?
- In Season 4, after the police piece together what the Trinity Killer must look like:
- Doctor Who:
- Subverted in "The Invasion of Time". The Doctor wants the Great Key of Rassilon from Borusa, who reaches up to an abstract wall structure made up of keys. The Doctor mentions that the best place to hide a tree is in a forest, but then he tosses the key aside, realising Borusa wouldn't give him the Key so easily. It turns out the real Key is stuck in the keyhole of Borusa's desk drawer.
- In "The Time of Angels", the Doctor goes hunting for a Weeping Angel... in a building of statues. The episode, were it not for the adventurous feel of the fifth series, would be Nightmare Fuel as anyone who's watched "Blink" can attest to.
- Naturally, the Nightmare Fuel comes roaring back in the last ten minutes. Why? Because all the statues are Angels.
The Doctor: And their image is their power. Power... Power! Ah, don't you see? All that radiation spilling out the drive! The crash of the Byzantium wasn't an accident, it was a rescue mission for the angels! We're in the middle of an army! And it's waking up.
River: We need to get out of here, fast.
- The Doctor lampshades it with a brilliant example of Metaphorgotten on top:
River: A needle in a haystack.
The Doctor: A needle that looks like hay. A haylike needle of death. A haylike needle of death in a haystack... of statues. No, yours was fine.
- Naturally, the Nightmare Fuel comes roaring back in the last ten minutes. Why? Because all the statues are Angels.
- The Halloween Episode of Hannah Montana has Miley trying to track down her evil identical cousin at her Halloween party to prevent her from stealing her fame by taking her blonde wig and claiming to be Hannah Montana. She anticipated this, so she themed the party around Hannah and required everyone to wear similar blonde wigs.
- A similar stunt was used by some thieves in the new Hawaii Five-0: knowing that there'd be video surveillance of the area where they heisted an armoured car, they dressed in painter coveralls and wore breath masks, having previously advertised for painters to show up at that location for a potential job with coveralls and masks.
- Happens by accident on Homicide: Life on the Street, when a murdered body is left in the morgue by a killer, and the incongruity isn't noticed for hours because no one thought to check how many bodies were supposed to be there. Turns out the killer hadn't even realized the victim was fatally injured and had laid the soon-to-be-corpse (his cousin) on a handy table to recuperate after they'd fought, then gone home.
- Rabbi Garfinkle explains on In Plain Sight that finding the needle is easy "If you are willing to look at each and every piece of straw." The rabbi has patiently spent years in a methodical search and successfully found one of Mary's witnesses. He tells her that witness protection works because "Criminals are lazy. That is why they are criminals. I on the other hand..."
- In the Season 2 finale of BBC's Luther, the numbers in a notebook turn out to be The Book Cipher used to communicate between two killers. This gives the police an Oh, Crap! moment when the suspect's Room Full of Crazy turns out to be full of books. But as any book used must not only be the same title but also the same edition, Luther realises this collection of secondhand books can't be the one used for the cipher. It's a Gideon's bible that the killers could find in any hotel room if needed.
- In one episode of MacGyver, Mac is carrying a valuable Chinese artifact which he needs to get rid of in a hurry—so he finds a shop selling cheap replicas of the thing and puts it on the back of the shelf.
- In The Mentalist episode "18-5-4", the Killer of the Week dresses up as a clown. She had earlier put out a fake casting call for clowns in a movie, so the police picked up several hundred clowns based on the witness description.
- Although Monk never did this in the main series, there is a case of this in the Expanded Universe novel Mr. Monk in Outer Space where a killer, dressed as a popular character from a TV show, shoots and kills the show's producer as he is arriving for a convention, then escapes into the convention center, vanishing because there are dozens of other people dressed in similar costumes to the killer's.
- Done at least once in Murder, She Wrote: The town is flooded with gossipy letters. Some are printed, some are written, some are typed; they're on all types of paper; and they are all mailed from Cabot Cove. In this case, the letters were sent by the killer, who had been told by the victim that her friend would mail a letter revealing their dirty dealings if anything happened to her. The killer inundated the town with mail, hoping the letter incriminating him would be taken as a joke.
- On NCIS, Ziva describes the task of finding a stolen defense system in a room full of computers as "looking for a needle in a needlestack". It was on what looked like an obsolete laptop which inexplicably had some modern PC ports and had a suspiciously fast boot-up time; the guts were state-of-the-art.
- The tribble bomb in the Star Trek: Deep Space Nine episode
"The Trouble With Tribbles""Trials and Tribble-ations", hidden in grain storage with all the other hungry (& dead) Tribbles.
- Used by name in Supernatural when talking about looking for cursed objects which, of course, look exactly like regular objects.
- In the episode "The Mentalists", when the heroes have to find a real psychic in a whole town of phonies, Dean states that "It's like searching for a needle in a stack of fake needles."
- In the seventh season finale "Survival of the Fittest", Sam and Dean finally get the means to kill leviathans. The problem? It only works once, so they have to use it on the boss leviathan. Upon learning this, said boss leviathan has several dozen or so of his underlings assume the same form as he does. However, he fails to account for the angel Castiel, who can perceive the leviathan's true form and, as a result of having briefly shared a body with them, knows which one is the Big Bad.
- In season 4, episode 3 of Taskmaster, one task had the contestants try to camouflage themselves as well as possible in one hour. Joe Lycett did this by grouping himself with ten other people wearing the exact same outfit and hat as him and all of them sitting with their backs to the camera. Greg was unable to figure out which person he was and Joe ended up ranking second in the task, coming behind only Noel who had ingeniously photoshopped himself into a scene as the banana in a fruit bowl.
- In The Wrong Mans, Phil thinks he's found the missing musical box he's looking for only to turn around and realise the room is filled with a collection of musical boxes, they're all different but as he doesn't know what the one he needs actually looks like, he's stumped.
- An artifact from Norse legends is Draupnir, a gold ring that creates eight non-enchanted duplicates when left alone overnight. Without applying some thought to the problem, it'd be easy to confuse the original for the eight valuable (but not magical) copies.
- In episode three of Mystery Show, Starlee goes to a meeting of chefs in Arizona looking for an elderly Swiss-German man named Hans Jordi and finds herself surrounded by a roomful of older men with European accents.
- In the Cabin Pressure episode "Uskerty", Martin's ring is swallowed by one of a flock of geese, and Martin can't tell which one. Fortunately, the airport manager lets him use the security equipment to find the ring.
- Anyone who's ever owned LEGO sets and kept all the loose pieces in a big box or plastic tub can tell you how hard it is digging around for the one piece you're looking for, never mind if you need a piece of a specific color.
- The same thing applies to jigsaw puzzles. For every piece, there are generally 2-4 other pieces that connect to it, but in the pile of hundreds or thousands of pieces that are on the table when you first open the box, it can seemingly take forever to find anything that matches.
- The one-trick one-room game 69,105 Keys, where you must find the one unique key to open the vault door.
- While most Hidden Object Game use the standard "needle in a haystack" approach, or blending it into the existing artwork, sometimes you have to find the correct object amongst a pile of similar objects.
- In NetHack, when running to the Astral Plane with the Amulet of Yendor, be sure not to confuse it for one of many Cheap Plastic Imitations of the Amulet of Yendor. There are a few easy ways to tell it apart. The genuine amulet cannot be placed in a container, and a plastic imitation is revealed by the "Identify" spell. The standard way to tell it apart is to name it the moment you get it.
- In Ultima Underworld II there's a room with a single Corp rune among a whole pile of Kal runes. All runes on the floor use the same sprite, but Kal and Corp are virtually indistinguishable anyway.
- One of the most mind-bending puzzles in the Infocom text adventure Spellbreaker required you to find a featureless magical cube hidden with eleven other featureless nonmagical cubes - using the JINDAK spell only three times. In a variant of the classic coin-weighing puzzle, you had to work out whether the real cube glowed more or less brightly than the fakes when you cast a certain spell by arranging the cubes into piles to use a process of elimination to find the right one. It was AGONY.
- The Elder Scrolls:
- There's a fairly small but highly intricate quest mod for Morrowind which at one point requires you to find a special key to continue. The only room it could possibly be in is entirely filled with keys. Every table and every nook and cranny of the room is covered in keys. As it turns out, the right one is sticking out from the lock in the door.
- Invoked and subverted in Oblivion's Shivering Isles expansion. In one quest, you're tasked with stopping several treasure hunters convinced they've found a ruin filled with riches when they've really stumbled into the fringes of the Realm of Madness. In one room, they are set before a giant cage filled with riches with a big, obvious lock. The "Manic" solution here is to dump thousands of identical keys in front of them but, since this is just a trap, none of them will actually open the cage. One of the adventurers will start frantically searching through the pile of keys to get the treasure and their obsession with finding the "right" one will drive them completely insane before their companion gives up and leaves without them. Fun stuff.
- In Monkey Island 2: LeChuck's Revenge, Guybrush has to find a map hidden within a pile of maps.
- Some maps in Prop Hunt allow for this strategy.
- In the Assassin's Creed: Brotherhood multiplayer game, there's an unlockable ability called "Morph", which, when used while stand in a crowd of people, will change all of them into duplicates of you.
- In Guild Wars, the lair of the ancient dragon, Glint, is hidden inside a single grain of crystalline sand, in what is aptly known as the Crystal Desert. While it might be possible to find that grain and magic your way inside, finding a portal inside a specific ruin is much faster.
- Resident Evil 0 has a clue for a hidden key be "To hide a leaf, put it in a forest." Since it's a leech-shaped key, you find it in the laboratory among the mutated leeches.
- At one point in Laura Bow: The Dagger of Amon Ra, the stolen dagger is hidden in the museum gift shop in a row of replica daggers. You can tell it's the real one because it doesn't have "Made in Pittsburgh" engraved on it.
- In the first Scribblenauts game, there is a puzzle where, when the answer is found, it causes a large number of Starites rain down from the sky. One of them is real; the rest are made of plastic, but look identical to the real one. This is easily dealt with by running across the pile since Maxwell automatically picks up any real Starite he's close enough to.
- Another Century's Episode uses this trope as a very tragic Sadistic Choice: Char Aznable places a devastatingly powerful bomb inside an ordinary space shuttle and sends it at Earth as part of a giant fleet of refugee shuttles. The heroes end up attacking the entire fleet to stop the bomb since they don't have the time to search every shuttle and it'll kill a lot more people if it gets to Earth. When footage of the attack circulates, the world at large believes the heroes have gone rogue.
- One King's Quest V puzzle includes a literal needle-in-a-haystack scenario, made more complicated by the fact that the needle is also a golden needle. Fortunately, Graham doesn't have to do the searching himself to find it.
- Dark Souls 2 uses this as a boss fight gimmick. The Royal Rat Vanguard is a rat with a mohawk and a good deal more health than most rats, which would make for a rather underwhelming boss if the battle didn't take place in a dark room packed full of rats. The fight ends up being less about the usual display of skill and more a desperate attempt to survive a pack of angry rodents long enough to find the one critter that will make all the others leave once dead.
- The Impossible Quiz's question 42: You have to find the 42 (Hint: It's 42). There are 50 on screen. The answer is the 42nd 42.
- In Policenauts, a criminal steals a woman's designer handbag, leaves a bomb in it, and puts it in a shop filled with handbags of the same make. Fortunately for Jonathan and Ed, the shop actually only sells knock-off handbags, resulting in a puzzle where the player must compare every single handbag in the shop to a genuine designer handbag and discard every one that doesn't match the real handbag they have.
- Panoptic has one player (a masked humanoid creature) hide in a crowd of identical masked humanoid creatures to evade the all-seeing and laser-eyed other player.
- Played with. Capital B and Dr. Quack's Evil Plan is to use a machine to suck up all the books in the world, supposedly to "leave [them] as the only player in the market." However, their bigger goal is to obtain one particular book, which is magical. They use the book-sucking machine knowing that it will suck up the one book along with all the others.
- Played straight later on. In Icymetric Palace, there's a room containing several duplicates of a Rextro Play Coin. Only one of them is real, the rest will injure Yooka.
- Final Fantasy XV did a crossover with Assassin's Creed in which the party attends the Assassin's Festival in Lestallum, with complimentary Assassin cosplay; every playable Assassin in the series thus far has their outfit cameo on at least one NPC, with the party geting Bayek's. After the first night the party spends at the Leville hotel, imperials show up looking for Noctis. Noctis' solution? Put his hood up so they don't notice his face, and hide in plain sight like the Assassin of legend. (The AC franchise exists in Eos.)
- Lampshaded and named in this Evil, Inc. comic, in which the company is searched for unusual activity.
- Pointed out by Florence in this comic.

- In Avatar: The Last Airbender, while the gang was hiding out in a Fire Nation city, they threw a party with all the kids at the school Aang was "attending". The party got busted by some Fire Nation military officials who were looking for the boy with the headband, which was Aang. Within seconds, all the kids had put on identical headbands so that Aang and the gang could sneak away unnoticed.

At one point, General Lane arrived with Titano's favorite toy, a plush monkey doll named Beppo that contained a music box which played "Pop Goes the Weasel" when squeezed, hoping that Beppo could calm Titano. Unfortunately Beppo wound up lost in a pile of non-musical toy monkeys during Titano's battle with Superman, which led to Lois telling Jimmy Olsen "Shut up and keep squeezing the monkeys!"
- In The Simpsons episode "Two Dozen and One Greyhounds," Mr. Burns is going to skin a bunch of Santa's Little Helper's puppies except for one, who stands up on his hind legs.

- In the Steven Universe episode "Steven and the Stevens", the legendary glass of time is hidden in an underwater temple filled with dozens of fake timeglasses.

- In "Sapotis", the titular Sapotis are imps that double each time they eat something. Their akuma is in their propeller hat and Ladybug knows that from the off, but they're all identical and grow in number so quickly that finding the real one soon becomes impossible; destroying the fakes only takes out that one copy. She ultimately rigs a contraption to gather all their hats up into a trash can and has Cat Noir Cataclysm it to destroy them all at once.
- The namesake Monster of the Week of "Gorizilla" has a strong sense of smell and uses it to look for Adrien Agreste. Once one of Adrien's fans neutralize the sense of smell, it's hard to locate him among the several billboards featuring him.
- In "Reflekdoll", Tikki and Plagg have to find Marinette and Adrien, respectively, after the two have been transformed into physical copies of the villain Reflekta, along with dozens of civilians. This leads to Swapped Roles when Plagg happens upon Marinette first, and she rolls with it rather than wait for Tikki to find her.
- Super Friends: In "The Case of the Dreadful Dolls", the villain Dollmaker creates clay dolls that allow him to control the people in whose likeness they are made. He manages to control all the Super Friends except El Dorado, who kicks his doll out of Dollmaker's hands. When Dollmaker attempts to retrieve it, El Dorado uses his illusion powers to surround the doll with dozens of copies, distracting the villain long enough for El Dorado to activate the fire sprinklers to destroy the dolls and free his friends.
- In the DuckTales (2017) episode "The Secret(s) of Castle McDuck!", Huey, Dewey and Louie at one point have to find a key made of gold that's buried among a pile of keys made of iron pyrite. Dewey thinks there's no way they can find it in time, only for Louie to find the correct key before Dewey even finishes speaking. He then tells his dumbfounded brothers that it was easy for him because he has knowledge of the different physical properties of gold and pyrite.
Louie: What? You like nerd stuff, I like gold.
- In one episode of Buzz Lightyear of Star Command, when one of Zurg's Grubs disguised as an LGM hides among a crowd of real ones, XR decides to flush him out by giving out Buzz t-shirts. All the real LGMs run up to XR, leaving the spy out in the open.
XR: Sorry, Buzz. Guess your spy isn't a fan.
Buzz: (Grabbing the Grub) The feeling's mutual.
- Batman: The Brave and the Bold: In the "Four Star Spectacular!" short "Flash in Double Jeopardy", Mirror Master attacks Flash with a neverending army of duplicates. Flash figures out thanks to an inadvertent hint from Abra Kadabra that Mirror Master's teeth are crooked, so they are reversed in the duplicates, allowing him to find the real one and knock him out.
- In a robbery from 2008, a criminal dressed in safety goggles, a respirator mask, and a yellow safety vest attacked an armored car and escaped...after using Craigslist to hire unwitting freelance handymen who showed up across the street from the bank, wearing similar outfits.
- On December 13, 2014, someone robbed a bank while dressed as Santa during 'SantaCon', a street party with many partiers dressed as Santa.
- The Temple of Mars in ancient Rome contained twelve identical shields. The story was that under the reign of Rome's second king, Numa Pompilius, a shield (ancile) fell from the heavens and it was prophecied that the future fate of Rome would depend on its continued ownership of this divine shield. So to guard it against theft, Numa Pompilius had eleven shields made that looked entirely like the original one and hung them all up in the Temple of Mars to be guarded by the college of priests called the Salii.
- Improv Everywhere pulled this by having the usual dozens of volunteers walk around a Best Buy shop dressed in khakis and blue polo shirts, making them nearly indistinguishable from the legitimate Best Buy employees who normally roam the floors.
- In one story from Not Always Right, a man living in a residential area adjacent to a golf course finally gets fed up with the jackass customers treating his property callously, as if it were somehow owned by the course, and dumps out an entire bucket-full of golf balls to prevent a trespassing golfer from finding a ball that had been hit into his yard.
- Some cryptographic techniques involve keeping the communication channel full of decoy messages so that an eavesdropper can't tell when you sent the real messages or how many.
- This is how One-time Pad Encryption works, and why it's impossible to crack. Even if you accidentally deciphered the intended message through brute force, there is no way to tell that it is the intended message (instead of any other possible message of the same length as the ciphertext) without the original pad. And if you have that, then there's no need for brute force in the first place.
- This is a common way of smuggling fossils out of countries. Make a stack of plaster copies of the fossil and hide the real one in the middle of them.
- Any mass deployment of military personnel. All their duffle bags are dumped out on the tarmac when they arrive, and all the duffle bags are identical. It doesn't take many deployments before experienced personnel start tagging their bag with a bright ribbon or something like that in order to make it easier to spot.
