->"''Tick-tock, tick-tock! Hook's afraid of a dusty old croc!''"
-->-- '''Peter Pan''', ''Film/{{Hook}}''

Where most stories rely on a suspenseful soundtrack to foreshadow the monster's attack, some go a step further, giving it [[ScareChord its own ominous theme]] in-universe. Either because it's been tagged with or entangled by a telltale noisemaker, or because it's ''eaten'' an audible mechanism -- often along with the person who'd been carrying it -- such a creature usually won't be much good at sneaking up on the heroes, as it'll be accompanied by a distinctive sound of its own.

The TropeNamer is the crocodile from ''Literature/PeterPan'', which had swallowed a clock and was always accompanied by a 'tick-tock' thereafter. FridgeLogic issues such as why the clock (radio, phone, etc) can still be heard through a large creature's belly wall, or why it doesn't run down and/or get expelled in time, are often ignored.

A subtrope of HellIsThatNoise, and a low-tech sister trope to SensorSuspense. Sister trope to ISophagus, may be related to WhyAmITicking. When someone tries to deliberately invoke this, it's WhoWillBellTheCat.


[[folder: Anime and Manga ]]

* Zaraki Kenpachi in ''Manga/{{Bleach}}'', arguably a predator, deliberately put bells on his hair to invoke this trope.


[[folder: Fan Works ]]

* In the ''Literature/{{Discworld}}'' tales of Creator/AAPessimal, any manifestation of the crocodile-headed Great God Offler is always accompanied by a muffled but audible ticking. Offler does not like to talk about this very much.


[[folder: Film ]]

* In ''Film/JurassicParkIII'', a ''Spinosaurus'' eats a man who's carrying a satellite phone. The phone is later heard ringing just before another attack, and again from a gigantic pile of dinosaur poop. [[GeniusBonus Bonus points]] since the ''Spinosaurus'' may have actually been the dinosaur equivalent of a crocodile.
* In ''Film/Tremors2Aftershocks'', one of the Graboids eats a radio that's blaring music, which is then heard from underground before it reappears.
** Although inaudible to the human ear, the vibration of an approaching Graboid can be detected by seismometers in the films and the series.
* In a variant, the monster from ''Supershark'' emits an energy that makes radios succumb to static when it comes near.
* While the noise doesn't actually warn anyone, the sound of a victim's cell phone can be heard ringing from inside the ''[[Film/SyFyChannelOriginalMovie Piranhaconda]]'' as it slithers through the jungle.
* The psycho killer Colt Hawker in ''Film/VisitingHours'' wears a small bell around his neck, which rings whenever he moves.
* This is invoked in both the Disney version of ''Disney/PeterPan'', and the live-action film ''Film/{{Hook}}''. Particular to ''Hook'', Peter and the Lost Boys taunt Captain Hook with a bunch of clocks, exploiting his deathly fear of their sound.
* In ''Film/KongSkullIsland'', when a Skullcrawler eats a camera. Just before it attacks again, the humans hear the camera's mechanisms whirring, and they can see its flash going off ''inside'' the creature when it strikes.


[[folder: Literature ]]

* Captain Hook's crocodile nemesis in ''Literature/PeterPan'' is the TropeNamer. It also averts the clause about FridgeLogic in the main description, as the clock running down is discussed by Hook and Smee as a definite possibility [[spoiler: and in fact does run down just before the climax.]]
* The BeastFable called ''The Bell and the Cat'' or ''The Mice in Council'' discusses a plan to [[InvokedTrope put a bell on a cat]] so the mice will hear it coming. Averted because [[WhoWillBellTheCat none of the mice are brave enough to actually install the bell]].
* In ''[[Literature/{{Nightside}} Hex And The City]]'', the RealityWarper Madman is preceded around the city by his own personal soundtrack, which is helpful to people who want to stay the hell away from him.
* In ''Literature/SewerGasAndElectric'', a sewer-dwelling mutant shark eats a tunnel worker whose new digital watch plays ''Bolero''. Its next appearance is heralded by the sound.
* Mrs. Tachyon from the ''Literature/JohnnyMaxwellTrilogy'' often runs into people with her shopping cart. Fortunately, it has a squeaky wheel that the local people have learned to listen for.
* In ''Literature/TooManyCurses'', the Vampire King who prowls the halls of Margle's castle is cursed to emit a constant sound of ringing bells, denying him any chance of stalking prey undetected. When a more powerful monster catches and devours his body, his ghost is left behind and free of the curse, but the creature that ''eats'' him becomes subject to this trope.
* In ''Discworld/WyrdSisters'', Nanny Ogg muses that Magrat's crush on the Fool has its up side: thanks to the tinkling bells on his jester hat, she'd always know where he was.
* Carl Sandburg "Rootabaga Tales" has a scene where baby alligators are fed with clocks. ("Peter Pan" and this book are only a few years apart and it's probably a ShoutOut.)
* Non-creature example: In ''[[Literature/{{Dragaera}} Phoenix]]'', Vlad travels to Greenaere on the trading skip ''Chorba's Pride''. He asks why the ship's head stay has bells tied to it just as the wind shifts, and demonstrates why the bells are needed: it's to warn people on deck so the boom won't swing around and hit them in the back. (Next time, he knows to duck.)
* ''{{Literature/Redwall}}'': In ''Triss'', a constant source of NightmareFuel is something that's only heralded by a sickly sweet smell, and causes even two certified badasses like Skipper and Log-A-Log to run like hell. It turns out to be three huge adders conjoined near their tails in early age by an entangling chain, the smell coming from their tails' necrotic flesh.
* In ''Literature/TheCarpetPeople'', the termagant is decked out in bangles and ornaments, presumably by its long-ago worshipers. These jingle as it walks, allowing Snibril to trace its movements ''without'' the risk of being TakenForGranite from looking at it.


[[folder: Live Action TV ]]

* Played with on ''Series/GetSmart'', "Ship of Spies": A [=KAOS=] informer is killed just before giving Max some important information. The only clue: the killer made an unusual "clip-clop" sound. They investigate and end up on the eponymous ship where it turns out just about everyone makes that clip-clop sound - a woman with castanets, a man with a peg leg, etc.
* The {{Clockpunk}} monsters of ''Series/DoctorWho'''s "The Girl in the Fireplace" make ticking noises as they move, and break the mechanical clocks around them so people won't notice that it's ''them'' ticking rather than a nearby timepiece.
** In the Christmas special "A Christmas Carol", a [[FlyingSeafoodSpecial flying shark]] bites off the tip of the Doctor's sonic screwdriver. He later detects that the missing part is coming closer, just before the shark attacks him and a young boy.
** If a Vashta Nerada swarm eats someone in a spacesuit, you can tell because the person's [[BrainUploading ghost-circuit]] will repeat the same thing over and over again.
* An episode of ''Series/{{Seinfeld}}'' has Elaine using this technique by giving a container of Tic-Tacs to a co-worker who is master of the StealthHiBye. All it does is drive her boss crazy, because the rattling of the Tic-Tacs is heard throughout the entire building constantly but nobody can tell where it's coming from because the man is still just as stealthy as before. Then Elaine had the [[SarcasmMode brilliant idea]] to pop a few Tic-Tacs herself while her boss was in the room, making him think she was the one making the sound all along.
* Averted on ''Series/{{NCIS}}'', when Abby tried to convince an intern to wear bells so she could tell if he (like her previous two aides) tried to sneak up behind her. Gibbs arrived and distracted her before she could press the issue.


[[folder: Video Games ]]

* In ''VideoGame/{{Persona 3}}'', if you stay on one level of Tartarus for too long, you will face having the Reaper spawn. You're able to tell he's close by the sound of chains coming from his direction.
* Throughout the ''Franchise/SilentHill'' games, the protagonists have radios which emit static whenever monsters are near--though it's never clear when exactly will they pop up.
* In ''VideoGame/{{Minecraft}},'' a second and a half before a Creeper explodes, you can hear the hiss of gunpowder igniting inside its body. This is especially scary because other than that hiss, Creepers are silent. Meaning you have no warning other than a second and a half of hissing before the Creeper explodes, destroying you (or at best severely depleting your health) and whatever you were building at the moment.
* In ''VideoGame/BatmanArkhamAsylum'', Killer Croc alludes to the Trope Namer, making ticking noises.
* ''VideoGame/StarcraftII'': Terrans can build a sensor tower that detects enemy presence in a huge radius. But since it doesn't reveal FogOfWar, there's no way of knowing what types of units they are, so what looks like a huge army may be be padded out with non-combat units.


[[folder: Western Animation ]]

* In the ''WesternAnimation/TomAndJerry'' short ''The Little School Mouse'', Jerry's last lesson for Nibbles is how to set this up by slipping a bell onto Tom. After he completely fails, Nibbles simply offers the bell to Tom as a gift, and the cat's ''thrilled'' with it.
* Parodied/blended with WhyAmITicking in ''WesternAnimation/{{Futurama}}'', in the following ShowWithinAShow excerpt from a film billed to have "a vampire AND an explosion":
--> '''Woman 1:''' Don't open that coffin! It's ticking\\
'''Woman 2:''' ''(with stake and hammer, over coffin)'' I have to! This coffin isn't going to open itself!\\
'''Dracula:''' ''(flinging open coffin and emerging)'' BLUUUUAAAH!\\
''(explosion, as advertised)''
* The ''WesternAnimation/LooneyTunes'' short "Bell Hoppy" puts a spin on the fable by having Sylvester the cat trying to bell a ''mouse'' (Hippety Hopper, the baby kangaroo that everyone thinks is a giant mouse). Not only does he keep failing, but everytime the bell rings the other cats jump out and beat him, thinking he's the mouse. Finally, Sylvester manages to bell Hoppity, [[spoiler:but then he is captured and put in a van. As the cats hear the bell and jump out, they are run over.]]
* In ''WesternAnimation/JakeAndTheNeverlandPirates'', the FridgeLogic is in full effect for the Tick Tock Croc, Captain Hook's crocodile nemesis, as the awful ticking is always heard whenever the croc draws near.
* In ''WesternAnimation/PeterPanAndThePirates'', when the Croc's clock runs out, ''time breaks down'' in Neverland. Tinkerbell ends up having to get in, wind the clock and get out to solve the problem.
* ''WesternAnimation/{{Daria}}'': In "Legends of the Mall", Metalmouth's approach was heralded by the sound of his metal dentures picking up radio signals and playing music. Oddly, the only thing they ever seemed to play was Cyndi Lauper's "Girls Just Wanna Have Fun".


[[folder: Web Original ]]

* A flash game Magic Pink Man gets meta about Boss battle music with world-building fluff about legendary monsters roaming the land heralded by unique music in their presence.


[[folder: Other ]]

* Common in tales of ghosts that are ChainedByFashion.


[[folder: Real Life ]]

* Cowbells, although mainly used for easy location of stray livestock, could also give a clanging warning when a ticked-off bull or ram was charging an unsuspecting target.
* Rattlesnakes use their tail rattles to scare off predators and [[HairTriggerTemper general annoyances.]]
** Or at least they're ''supposed'' to. Sometimes, however, a rattler will strike, ''then'' rattle.
* One particularly tragic example was invoked in certain regions of India. "Untouchables" (people of "unclean" [[TypeCaste castes]], such as garbage collectors or leatherworkers) were generally despised, and people feared that even interacting with them would corrupt one's spiritual energy. Therefore, when Untouchables left their segregated communities and entered areas with other people, they had to sound a wooden clapper to warn others to get out of the way.
* Medieval lepers carried bells or clappers to warn other people of the risk of contagion; the sounds these devices produced also constituted a plea for charity.
* Not a threat, but tin cans strung behind the vehicles of "Just Married" couples provide a rattling declaration that newlyweds are approaching.
* Supposedly, Gan Ning (of the [[Literature/RomanceOfTheThreeKingdoms Three Kingdoms]] period) wore bells on his waist sash to frighten his enemies.
* Japanese and Chinese monks carried around a special staff tipped with rings called "Shakujo". The sound of the rings was used to warn people of the monk's coming (as a plea of charity) and to ward off animals.
* Inverted in the many, many cultures where making loud noises -- banging pans, ringing bells, fireworks -- as one travels has been alleged to ward off monsters or evil spirits.
* Some cat owners put bells on the cat's collar to warn birds or small animals the cat might be stalking. Many cats learn how to either stalk without jingling or get rid of the bell (and possibly the whole collar).
* Since the invention of cell phones, there have been instances of [[https://xkcd.com/207/ ringing dogs]]. If a dog is big enough to swallow a phone whole, the phone can still ring, letting people know they need to go to the vet and the phone store, ''definitely'' in that order.
* In WWII, the German Stuka dive bomber had so-called "Jericho Trumpet" sirens ([[JustForFun/TVTropesWillRuinYourVocabulary known on this wiki]] as the StukaScream), driven by the propeller when diving. This let everyone know that ThoseWackyNazis were about to ruin your day, and that there was nothing you could do about it.
** The Soviet equivalent were the [[https://en.wikipedia.org/wiki/Night_Witches Night Witches]]: female pilots who flew bombing missions by gliding over the enemy lines at night, so the only sound heard was the engine while taking off, [[ParanoiaFuel then silence]].
* Riders for the Yam, a horseback messenger system established by the Mongols for rapid communication within their Empire, wore jangling bells to alert relay posts of their approach so fresh horses could be brought quickly to them, and to warn travelers on the caravan routes to clear a path for the Great Khan's mail carriers.
* The sirens of ambulances or fire engines are intended to warn other drivers to pull over and clear the way for such emergency vehicles. Although intended as a safety precaution, the sound itself can be alarming to drivers who can't find an opening along the shoulder to slip into.
