This creature normally doesn't look or act like an enemy, and [[EverythingTryingToKillYou unlike everything else]], it's not interested in your blood. It's simply there to provide flavor. However, if you attack it or otherwise provoke it, it will turn on you and dish out the hurt.

Most commonly this is programmed as a form of VideoGameCrueltyPunishment. Video games are rather infamous for having player characters who can still be considered "the good guys" no matter how much petty rampaging they engage in, so even to this day a harmless creature that suddenly turns vicious can catch gamers off-guard, forcing them to question whether engaging in your inner JerkAss is ''really'' worth having to start the level over from scratch.

* ''Franchise/TheLegendOfZelda''
** Multiple franchise installments have the Cuccos, vicious birds who many old-school gamers can recognize by name as being this trope. In every game they appear in and are attackable they'll gang up on Link and viciously destroy him should he poke them with his sword one too many times. In some games the barrage will stop if you survive long enough, but in others the only escape is to leave the area or die.
** In ''VideoGame/TheLegendOfZelda'', if you attack [=NPCs=] with your sword, the fires next to them start flinging fireballs at you.
** ''VideoGame/TheLegendOfZeldaTheWindWaker'' replaces them with pigs. If you return to the first island you'll find that the pig you caught at the beginning of the game is now HUGE. It can be provoked just like the other pigs. It does more damage than any other enemy in the game when it attacks- including the FinalBoss!
** In ''VideoGame/TheLegendOfZeldaOracleOfSeasons'', you repeatedly defeat the Moblin King until he's living in a one room house in a village making bombs for sale, utterly disheartened at how low he's fallen, to the point where makes no attempt to harm you. If you put a bomb in his stockpile, however, it's the final straw, and he and his mooks run outside and watch the house explode- with you still in it.
* ''VideoGame/SuperMetroid'' has a turtle-like creature and its adorable babies in a certain room in Maridia. While they're normally utterly harmless, if you attack the little ones, [[MamaBear the mother will immediately spin around in her shell after you.]] This is how you can reach an item upgrade [[SequenceBreaking before acquiring the Space Jump]].
* The Game Boy Advance RPG ''Dokapon'' had the Shopkeepers. While they would never pick a fight with you, you could [[ShopliftAndDie pick a fight with them... Ouch.]]
* In the jungle stage of ''{{VideoGame/Contra}} Hard Corps'', there's an apatosaurus whose back you land on after defeating one of the stage's minibosses. You have to walk up his neck and over his head to move on, but if you shoot his face, he'll unleash a stream of white-hot plasma DEATH out of his nose. In the Japanese version where you could take up to 3 hits before dying ([[OneHitPointWonder unlike the US version]]), this is the only attack in the game that [[OneHitKill kills you instantly]].
* A not-really-an-enemy example: ''VideoGame/EarthwormJim'''s Peter The Puppy. You have to escort him across a level full of dangerous enemies and pits. You can't hurt him, but if an enemy does, cute little Peter will morph into a giant monster and maul the heck out of you. Then he'll drag you to the nearest checkpoint before turning back to normal.
* In the ''VideoGame/PokemonMysteryDungeon'' series, you can occasionally find shops in dungeons. Attempt to shoplift, and you'll face an army of extremely high-level Kecleon with max stats. Even if you're prepared, they'll probably wipe the floor with you. The worst part is that [[GottaCatchThemAll this is the only way to recruit a Kecleon for your Rescue Team.]]
** The shopkeeper can also go ballistic on you or the enemies if accidentally struck by an attack. His behavior is rather unpredictable in that regard, so fighting around him is generally a bad idea.
** The shopkeepers in the ''ChocoboMysteryDungeon'' series look like the ''GrimReaper'' and are ungodly powerful. Naturally you need to kill one to achieve HundredPercentCompletion.
* In ''VideoGame/Left4Dead'', the Witch does nothing besides moan, sob and cue creepy music. If you attack her in any way (be it by bullet, melee, explosion or fire), get too close to her, shine your flashlight at her for long, and in some cases, look at her too long, she'll get startled, which means she'll run at you faster than a survivor can run when not under the effects of an epinephrine boost (although [[KillItWithFire not when she's on fire, then she's slower]]), claw the offender for either an instant incap or, on higher difficulties, a OneHitKill, and if said offender is incapped, she'll rake ''furiously'' at them. In some versions she'll rampage against the the other party members, too, out of sheer spite, and in all cases, she'll switch targets if another survivor [[ManOnFire lights her up]]. Sneaking past is the preferrable option, although the Director is often smart enough to spawn her at a chokepoint with no way around, and vanilla bots don't have enough AI to run past her one at a time, and that often forces the player to kill her by any means possible. While she's a {{Demonic Spider|s}} when all four Survivors are together, in any game mode where the player is alone, making stealth ''far'' more manageable, she's rarely more than an annoyance and a slowdown in pace, even less so than the Spitter.
** A particular example of this: the sugar mill. Even a single Survivor might have trouble weaving through dozens of the bitches.[[note]]This is an AscendedGlitch; the Director had an odd tendency to roll a lot of Witches for the area, and the designers decided it was worth hardcoding.[[/note]]
* Most cashiers in the ''VideoGame/GrandTheftAuto'' games can be robbed at gunpoint, but those in the gun shops and high-class nightclubs carry shotguns and ''will'' bust a cap if you try anything funny. Oddly, this can work to your advantage as if you're trying to kill some annoying gang members and can't quite get the police to aggro them. Gunshots will attract the police, who'll kill the cashiers, which will cause cashiers to become more aggressive in their behavior, and probably shoot or beat to death the wandering gangers. Good for when your objective is to kill one of their number and they're mulling about near both the target and the gun store/nightclub. Just aim your gun at the cashier and duck behind someone else.
* In ''VideoGame/TempleOfElementalEvil'', there are several locations which automatically spawn groups of giant rats (such as the Moathouse entry hall). Unlike most rats you'll meet, these are not hostile. You can attack them, but if your party is low level (which is usually the case) you could end up with a couple of diseased characters. The rats mostly serve the purpose of indicating that a location is not healthy for sleeping.
* In ''VideoGame/{{Age of Empires|I}}'', elephants (except for King Elephants) only attack if you hurt them first. While they're dangerous to hunt as a result, you can safely ignore them. This is a big contrast to lions and crocodiles. Wild boars in ''VideoGame/AgeOfEmpiresII'' are similar: attempting to hunt one for food will likely end up with a few dead villagers on the side as a result.
* The Big Daddies fill this role in ''VideoGame/BioShock1''. They'll lumber past ignoring you all day long, at worst shoving you aside dealing zero damage if you stand in their way, but if you take a shot at them (or their Little Sister) they won't stop until one of you is dead. But if you do kill them, you can both capture the Little Sister and loot their bodies for money and ammo.
* The Zombie Pigman from ''VideoGame/{{Minecraft}}'' will even walk right up to you ''and look at you'' without attacking. When you attack him, not only does he attack full-on with his sword, but any other Pigmen in range come in swinging, and on the normal difficulty, they can take off a quarter of your maximum health with one hit. The game actually encourages you to attack them by making them drop gold nuggets, which is more fun than mining for gold and arguably faster. Wolves behave with a similar pack instinct, except you can also tame them so that they'll gang up on monsters that attack you. Spiders are hostile at night, but turn into this in the sunlight, albeit without the group attack. However, due to how the AI works, you can kill them without fear of reprisal by maneuvering them into harmful obstacles like cacti, nudging them off cliffs, or starting a fire ''under their feet''.
** The Endermen are a weird case because they define "provocation" as "looking directly at them." However, so long as you keep your crosshairs away from their noodly torsos, they'll just wander peacefully around [[BanditMook carrying their blocks]].
* The [[EasilyAngeredShopkeeper Shopkeepers]] in ''VideoGame/{{Spelunky}}'' are like this. Even worse, killing one directly would cause all the other shopkeepers for the rest of the game to be hostile as well.
* In ''VideoGame/FinalFantasyXII'', you may see a large [[TyrannosaurusRex T-Rex]]-esque creature wandering around a very early area of the game. It's harmless as long as you leave it alone. If you're [[WhoWouldBeStupidEnough foolish]] enough to run up and [[BullyingADragon smack it]], [[CurbstompBattle don't expect to live for much longer]]...
** The Elementals and Entites too. They appear in a variety of locations, all the same level regardless of region (so in some places they're overpowered and in others remarkably weak). Unfortunately, casting magic anywhere near them will also set them off.
** Similarly, the Long Guis and Shaolong Guis in ''VideoGame/FinalFantasyXIII'' and ''VideoGame/FinalFantasyXIII2'' ignore you completely unless you deliberately pick a fight with them. They don't show up nearly as early as the FFXII example, but are still strong enough to OneHitKill you when you first encounter them. By the postgame of XIII, however, you'll be farming them if you want to achieve OneHundredPercentCompletion.
* For a short time, ''VideoGame/WorldOfWarcraft'' had [[ Gamon]] in the Horde capital. He was originally level 13 and frequently killed by Horde players for no reason. However, just before the Cataclysm expansion, Gamon was [[TookALevelInBadass raised to level 85]], past the previous expansion's level limit, allowing him to deal enough damage to one-hit players attacking him. Gamon's status as a savage setpiece disappeared as Cataclysm released, allowing players to reach level 85.
* ''VideoGame/GuildWars2'' has a substantial amount of neutral fauna, ranging from roving herds of moa to lumbering oakhearts. They typically will not actively engage anyone, but if hit by anything (players or enemy mobs), they will defend themselves.
* ''VideoGame/MarioAndLuigiSuperstarSaga'' has Oho Jees. Attacking these [[CloudCuckooLander oddballs]] with elemental moves triggers a battle. Incidentally, defeating them doesn't kill them; they simply return to normal, harmless, friendly blobs.
* In ''VideoGame/TheElderScrollsIIIMorrowind'', Netch are a species of [[LivingGasbag Flying Jellyfish]] native to Morrowind and are farmed for their leathery skin by the Dunmer. Whether wild or farmed, they won't attack you unless provoked. However, both the large, poisonous male and the smaller, more physically damaging female can easily dispatch a low-level player.
* A less 'non-enemy' variation of this can happen in ''VideoGame/NeverwinterNights''. For example, in one dungeon in the first chapter of the original campaign its boss will animate the occasional corpse just to taunt you as you enter a room. ''That'' corpse (unlike any other undead in the same location) will be harmless and just collapse on its own after saying its piece if left alone, but if attacked will start to hit back and turn out to be effectively indestructible...
* In the ''VideoGame/BaldursGate'' series you can find [[BearsAreBadNews bears]] around in earlier stages of the game. Unlike other creatures you find on the map, they mind their own business and don't attack you, unless you come too close. Unfortunately for a budding hero fresh out of [[NoobCave Candlekeep]] a single black bear can quickly overwhelm low level fighters and end your journey abruptly.
* The King P Statue in ''VideoGame/{{Mother 3}}'' is normally nothing more than a background element found in the upper right corner of New Pork City. However, you can choose to provoke it, in which case it will come to life and, unless you know a secret to defeating it, hand you your ass on a silver platter.
* ''VideoGame/XenobladeChroniclesX'' is absolutely ''lousy'' with these; the world is filled to the brim with monsters, a number of whom won't attack you unless you provoke them. The enormous Millesaurs are the earliest example. They're some of the largest and most powerful enemies in the game, but will ignore you as long as you leave them alone. The most extreme example is the game's BonusBoss: [[NamesToRunAwayFromReallyFast Telethia, the Endbringer]]. It's completely non-hostile, but if you attack it it's the single most powerful enemy in the game.
* ''VideoGame/{{Pikmin}}'' has sleeping bugs that sleep unless you a) get too close to them or b) attack them. You can find out which is which by looking at their eyes. The ones with half open eyes have the lighter slumber.
* ''Videogame/{{Kirby}}'': The Scarfies are recurring adorable mooks who simply float in the air, being completely still. However, if Kirby try to [[VacuumMouth inhale]] them, they'll suddenly turn into hideous cyclopean critters who try to bite Kirby. Subverted in some games where sometimes they'll slowly drift towards Kirby (with the same hideous face) if he turns his back on them.
* Stuart Smith's ''VideoGame/AdventureConstructionSet'' had "Aggressive Neutral" as a possible AI setting for creatures. This type of creature will move around on its own, but won't attack unless the player (or some other Aggressive creature) hits it first. It then swaps to either "Aggressive Friend" (if an Enemy hit it) or "Aggressive Enemy" (if you did). Given the incredibly bad aim characters tend to have with missile weapons, accidentally triggering them is not difficult.
