In a situation where a character not unlike the Technicolor Ninja is trying to sneak around unnoticed, their attempt at stealth will suddenly be threatened by them stepping on a dry twig, sneezing, knocking something over, setting off an alarm, blowing their cover, or otherwise alerting others to their presence. If no one notices, they might be okay in the worst case, they might be captured, or have to face the enemy in a full-blown battle. Either way, heads will turn suddenly.
Note that this trope often applies in situations where it would make no sense in real life for guards to be so super-sensitive, given the likelihood of the most startling noises being a Cat Scare. When considering what the hero is doing there in the first place, this falls Right Under Their Noses.
As a result, savvy sneaker-uppers will toss a stonenote so that it lands with a "plunk" in the direction opposite their position to make the guards go investigate see Throwing the Distraction. The guards, even seasoned Border Patrol, will always go for this old chestnut. If nobody notices when they really should have, see It's Probably Nothing and The Guards Must Be Crazy.
This trope can be done by the player in any Stealth-Based Game when you blow your cover. Say, for instance, you trip an alarm, forget to hide a body, or just walk into a room full of guards. From there you either go guns blazing or reload a save.
If the attempt at stealth is laughably inept, see With Catlike Tread. If their attempt is good but they're still caught, they're dealing with The Anticipator. For moments where the infiltration itself goes unnoticed but the escaping part is when you're discovered, see Starts Stealthily, Ends Loudly.

Instead, the rooster quietly chirps, causing Usopp to scream in shock, "ROOSTERS DON'T MAKE THAT KIND OF SOUND!"

The Matilda's partner tank uses that to nail them.
- A variant in Death Note. L at one point starts going on a lecture of how important stealth and discretion will be in the investigation, and under no circumstances must they reveal themselves.

Fairy Godmother: Now, we have to go. I need to do Charming's hair before the ball. He's hopeless. You know, he's all high in the front, he can never get to the back. You always needs someone to do the back of your hair.

- Warhammer 40,000's Ork Kommandos operate on similar logic, going around invisibly setting explosives and backstabbing sentries so they can enjoy the looks of terror on their victims... at least until the first one can't take it anymore and charges yelling WAAAAAAAGGGGGHHHHHH! Back when Madboys were still in the fluff, there was mention of how they were a liability in the best of cases, like deciding the best time to have a shouting match is in the middle of a night raid.
- The Genesis game Toe Jam And Earl: when you tiptoe past a sleeping enemy you would occasionally sneeze and awaken it.
- Team Fortress 2: Happens all the time playing Spy, unless you're really good, and even then you occasionally just bump into a pyro and get set aflame.
- Can happen in the Metal Gear games, if you're not careful, from the singing sand in Metal Gear 2: Solid Snake to twigs on the ground in Metal Gear Solid 3: Snake Eater - notably, a lot of cases of this are deliberate traps on the part of the group you're infiltrating.
- Kya: Dark Lineage is not as much about as "what breaks your stealth" but more as in "do I kick their ass if they spot me, run the f*ck away or get my ass hand to me". Of course at one point you have to stealth and platform through a tight room with Wolfen guards, spikes, insta-kill floor, and what-not. What breaks your cover? You open the gate to the next level, locking down any deadly traps.
- Uncharted forces you to do this at some point - you'll always be spotted when you enter an area with the enemies unaware.
- Eternal Darkness has an enemy example. In one chapter you are being stalked by an invisible "vampire". While you can make it visible by casting a simple spell, if you don't have time you can tell where it is when it knocks some things over (particularly in the basement when you destroy its source of power and kill it for real).
- Said word-for-word by Barney Calhoun in Half-Life 2. He announces that your group will have to sneak through the Overwatch Nexus, a pre-war public service building to take down the Suppression Device (a Combine Dark Energy Mortar) - then, as soon as he opens a door, a camera spots you.
- In the Thief series, you can be given away if you move across surfaces made of metal, stone or anything else which makes a noise when you walk on it. It isn't an instant giveaway though: one sound may make a guard suspicious, two will make him start looking around. Remain hidden and quiet and the guard will eventually conclude "Just rats." and return to patrol.
- Can happen in Heavy Rain when Shelby's trying to sneak up on a robber. If you fail a Quick Time Event, Shelby will step on some potato chips and alert the robber.
- In the Mass Effect 2 Kasumi DLC, you can accidentally set off the alarm clock while searching Hock's bedroom for DNA. The guards come running, but only if you snuck in instead of faking security clearance.
- Happens so often to Faith in Mirror's Edge that sneaking is more like waiting to be spotted.
- In the Pokémon games, Zorua and Zoroark have the ability to take on the appearance of other Pokémon in your party. And it can really work when battling another person... Until you use an attack that the Pokémon they're disguised as can't learn. The illusion also fades the moment they're hit by an enemy.
- Scorch of Star Wars: Republic Commando will occasionally say this after an explosive charge is detonated.
- In World of Warcraft to prevent stealth runs (a party consisting entirely of druids and rogues using stealth to avoid all enemies but the bosses) certain enemies are fairly arbitrarily given the ability to see through stealth. Some bosses will also alert a huge portion of the dungeon when attacked, or at least call in back-up that is likely to also drawn in other mooks that were skipped.
- In Deus Ex: Human Revolution, guards are often overly sensitive to sounds you make, even when the situation doesn't call for it. If there are footstep sounds from the bathroom, somehow they immediately know it's you and not a civilian worker or another guard tending to their business. It seems even more glaring given that they don't notice many things which are highly suspicious, like huge crates mysteriously moving around while they're not looking and their colleagues not showing up on their patrol.
- A similar problem to the above example is Alpha Protocol. Brutally beat a guard into unconsciousness with your bare hands? No problem for the guys in the next room. Walk around at the same speed and path as the guard you just knocked out? They'll all come running.
- Worms has an invisibility gadget that cloaks your entire team—but once a worm attacks, its position is revealed. Using Invisibility, then attacking, wastes the item.
- In Halo 2's mission "Uprising", after you have just taken out a few Brutes and met with some more Elites, several drop pods crash into the ground, giving the Arbiter reinforcements. One of your more Genre Savvy comrades remarks "So much for a stealthy advance".
- In The Hobbit for the PS2, when Bilbo has to sneak past the trolls to save the dwarves, stepping on dry twigs alerts the trolls to his presence.
- The stealth part in Stage 5 of Hard Corps: Uprising is optional. You can choose to go through the stealth part of the stage guns blazing.
- This is pretty much every player's reaction in PAYDAY 2 if stealth fails since SWAT are now on their way.
- In Code Name STEAM, if any agents get noticed by the aliens, they'll inform the others that they've been spotted. John Henry even says the trope name at times.
- Mass Effect: Andromeda: Several times, Ryder and their team encounter some Remnant bots which they try to sneak past. It inevitably results in Ryder and team being spotted and having to shoot their way through anyhow. And again when trying to infiltrate the Archon's ship. They get spotted the very second they go through the door.
- Due to the procedurally-generated nature of maps in Warframe an unlucky Tenno might hack open a vault door only to find a guard on the other side who happened to be looking right your way when you entered and have to taken them out before they can run to a console and trigger the alarms.
- Worse if it is a security drone as those can trigger an alarm instantly upon seeing you.
- In Granblue Fantasy, Anthuria runs away from a group of suitors with the help of the Captain, Lyria, and Vyrn. When the four of them decided to hide in a narrow space between two walls, the captain's hand accidentally tickles Anthuria. The Erune's sudden orgasms then gave away their presence to the suitors.
- XCOM 2: It's not uncommon for an ADVENT patrol to walk into a position where they flank the cover of one of your concealed soldiers, which is an automatic reveal.
- The No-Gear Level of Metroid: Zero Mission, where an armorless Samus is forced to infiltrate the Space Pirate Mothership, operates like this. You have one chance, and only one chance, to get through stealthily, and being spotted or tripping an alarm even once permanently puts the pirates on alert and sends them actively looking for you. It is extremely difficult to pull off a successful stealth run, as it requires lightning-fast reflexes, wall jumping, and planning ahead to pull off, but thankfully just charging through while being pursued by Pirates is fairly easy (albeit not nearly as satisfying).
- Resident Evil 6 gives Ada exactly one chance to infiltrate the submarine without being seen: once the J'avo guards are alerted to your presence they sound an alert and reinforcements just keep coming. Again, like the Metroid example above, Ada has plenty of ammunition, cover, and resilience to just Leeroy Jenkins her way through but it is just so satisfying to slip through Back Stabbing guards without ever being detected.
- The Order of the Stick:
- Spoofed in an early installment, where one of the heroes fails his Move Silently roll while the group is trying to sneak invisibly past a room full of guards. Each of them states the roll they made, and the noise that attracts the guards' attention is the sound of Elan yelling "I GOT A FOUR! DID YOU HEAR ME? I GOT-!"
- In a later strip, the group is trying to sneak into a bandit camp to save Elan (who rolled that 4), Belkar gets bored while someone else is trying to devise an effect stealth plan and just starts a fire instead, drawing the attention of every guard in the camp and getting the group caught.
- Elan does it again in Breaking In Is Hard To Do as a Call-Back to the first example, only this time he got a 9. "YOU KNOW, BECAUSE THE BOOTSnote ADD FIVE."
- Inverted in one of the first strips, when the entire group fails both spot and listen checks and ends up surrounded by goblin ninjas.
- In Strays, how Meela notices Feral again.
- In Charby the Vampirate Daray fails to actually knock out his initial attacker when he returns to a village with a kill on sight bounty on his head and she loudly declares his presence to the whole village as he tries to sneak away after punching her.
- In Goblin Hollow, one character botches a Move Silently roll, and his character trips. The guard turns out to be deaf as a post.
- In The Specialists, what gives Hartmann away. Then again, he did want to make contact with them.
- Happens to Rory in Demon Fist when he's trying to infiltrate Duprant's mansion. Giving a Big "SHUT UP!" to the arguing demons in your arm will do that.
- Invoked and Played for Laughs in Darths & Droids, where the group's plans for what to do when the stealth mission fails are more detailed than their plans for the stealth mission itself. After all, which set of plans is more likely to be used?
- This Awkward Zombie strip, where its used in a Double Subversion: Much like in the game itself, the guards ignore the loud noise of a barrel falling off a shelf, but the sound of Adam walking immediately sets them off.
- Evil Overlord List #139: If I'm sitting in my camp, hear a twig snap, start to investigate, then encounter a small woodland creature, I will send out some scouts anyway just to be on the safe side. (If they disappear into the foliage, I will not send out another patrol; I will break out the napalm.)
- This video clip about an astronaut who avoids confrontation with a monster... NOT!
- In RWBY, when Yang enters Raven's camp and distracts everybody, Weiss takes the opportunity to quietly work on her escape while no one is watching. After her cover gets blown by Yang punching a guy through a tent that's hiding her cell, Weiss decides subtlety is out and summons her Knight clone to shatter the cell into matchsticks.
- Adventure Time: In "Normal Man" Finn, Jake, and Normal Man try to sneak past the many obstacles of Wild Trap Mountain. The only make it up to the Man Eating Plants before their cover is blown when one of them tries to eat Jake, forcing them to run for it.
- Harley and Ivy from Batman: The Animated Series meet at the Gotham Museum, each stealing some from it at the same time. Harley sneaked into the museum in a way that would impress Catwoman, and was part way through cutting open the display case of a large diamond when the alarms went off anyway. She turns around to see Ivy running past, so Harley says "to heck with it", smashes the case, grabs the diamond, and runs.
- Family Guy parodies the above-mentioned Return of the Jedi example with Peter/Han stepping on a twig, a sheet of bubble wrap, a bike horn, a dog's tail and finally a radio. And the guard only notices because "Hey, I love this song!"
- In the My Little Pony: Friendship Is Magic episode "Power Ponies", Twilight Sparkle starts telling her friends a plan for how they can sneak into the supervillain the Mane-iac's hideout. Rainbow Dash, who wasn't paying attention, suddenly charges up to the front entrance and starts yelling for the Mane-iac to come out and fight. Annoyed, Twilight says, "So much for the element of surprise."
- In the third part of Sonic Boom's "Robots from the Sky" Story Arc, Sonic suggests he and Tails take a stealthy approach to get further into the robot-populated sky city of Morristown and find out what's going on... and then trips an invisible laser. With his first step. This forces the two to run from the ensuing guards, who they can't destroy because they're infected Morristown civilians.
- SpongeBob SquarePants: In "The Secret Box", SpongeBob is sneaking through Patrick's house, but every step he makes a very loud (and unrelated) noise. Fortunately even after he causes a ruckus Patrick is still asleep... until SpongeBob comments on what a heavy sleeper he must be.
- Star Wars: The Clone Wars:
- "The Gungan General": During the second escape attempt the trio is seen carefully sneaking through the halls avoiding being seen or making too much noise then, after a cutaway to Jar Jar's group, they're next seen sprinting down the hall knocking everything they can over behind them and kicking doors open so something evidently blew their stealthy approach.
- "A Distant Echo": Anakin reminds the strike team that their incursion into Purkoll is supposed to be a stealth mission, so no blasting. Rex reacts with the trope name word-for-word when the turbolift door opens on to a room full of battle droids and the Bad Batch immediately moves to engage them.
- Star Wars Rebels:
- "Stealth Strike": Captain Rex's word-for-word reaction when Kanan starts shooting onboard the Interdictor, blowing their cover.
- "Steps Into Shadow": Once the rebels (who intended to sneakily steal Y-Wings scheduled for destruction from Reklam Station) are discovered, their plan immediately morphs into shooting everything in sight and destroying Reklam Station in order to steal the ships.
- In the Superman: The Animated Series episode "New Kids in Town", young Clark Kent is attempting to sneak around Brainiac, who's travelled back in time to kill him, however he knocks a rake over, attracting Brainiac's attention.
- Totally Spies!: In "Wild Style", the girls sneak into the lair of an evil fashion designer who is turning people into animals so she can make them into coats. However, they're looking in while Clover is turning into a lioness, and Alex happens to be allergic to cats.
- Dr. Venture of The Venture Bros. has a moment like this when he accidentally drops a lightbulb that his bodyguard Brock Sampson asked him to unscrew for total darkness, thus alerting the nearby guards. After saying the trope name, Brock replies with an alternative plan: Throwing the Doctor into the group of incoming guards. Surprisingly, it works.
- X-Men: Evolution: The X-Men and Mystique in an Enemy Mine situation sneak into where X-Men and Brotherhood captives are being held. Iceman ice-bridges over the Laser Hallway's sensors, uses the key they'd stolen to open something... and then, as he's confidently spinning the key on his finger as he quips to Kitty, the key flies off, and to the floor, triggering the alarms.
- Young Justice: A recurring theme in this series is The Team being given strict orders to perform recon only on missions, but things don't always go as planned.
Beast Boy: Psh, they always say "recon only". It never works out that way.
- Not really Truth in Television. Most people acting as guard or something similar won't react to the odd sound unless it's something that indicates human presence, such as vocal sound or the constant rhythm of footsteps. The sound of a snapping twig won't give you away unless you're trying to avoid someone who's very alert, or already knows that you're there.
