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.

* ''Zelda''
** 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.
** ''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/TheLegendOfZelda'', if you attack [=NPCs=] with your sword, the fires next to them start flinging fireballs at you.
* ''Super {{Metroid}}'' 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 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 ''{{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, this is the only attack in the game that kills you instantly.
* A not-really-an-enemy example: ''VideoGame/EarthwormJim'''s Peter The Puppy. Just Peter The Puppy.
* 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 and cue creepy music. If you attack her, get too close to her, or in some case look at her too long or shine your flashlight at her, she'll run at you and kill you in seconds. In some versions she'll rampage against the the other party members too out of sheer spite.
* 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.
** Also, wild boars in VideoGame/AgeOfEmpiresII. Attempting to hunt one for food will likely end up with a few dead villagers (and boar) as a result.
* The Big Daddies basically fill this role in ''VideoGame/{{Bioshock}}''. They'll lumber past ignoring you all day long, 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 capture the Little Sister and loot their bodies for money and weapons.
* The Zombie Pigman from ''{{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 ''{{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). Unfortunatly, casting magic anywhere near them will also set them off.
** Similarly, the Long Guis and Shaolong Guis in ''VideoGame/FinalFantasyXIII'' and ''{{VideoGame/FinalFantasyXIII-2}}'' ignore you completely unless you deliberately pick a fight with them. They don't show up nearly as early as the FFXII example, but they are very powerful for when you first encounter them. By the postgame of XIII, however, you'll be farming them if you want to achieve OneHundredPercentCompletion.
* ''VideoGame/WorldOfWarcraft'' has a neutral NPC named [[ Gamon]] in the Horde capital. He used to be the general beating doll, then apparently TookALevelInBadass and can now deal enough damage to one-hit players attacking him.
* ''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.
* ''MarioAndLuigi'' introduced 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 blobs.
* In ''VideoGame/TheElderscrollsIIIMorrowind'', the netch are non-aggressive animals resembling large flying jellyfish, but they can easily dispatch a low level character if provoked, especially the females
* 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.
