[[caption-width-right:320:[[TropeNamer Accept no substitutes]]!]]

Sometimes, horrifically dangerous objects are obvious; nasty-looking {{spikes|OfVillainy}}, painted [[DarkIsEvil dark and foreboding colors]], covered in SchmuckBait, and generally like something straight from a 12-year old's ''TabletopGame/DungeonsAndDragons'' game. However, sometimes it looks like a cute kitten statue.

Aww... [[KillerRabbit nothing that cute could be dangerous]]. Until it comes cutely to life and uses its precious widdle claws to rip your face off. [[DepartmentOfRedundancyDepartment Adorably.]]

A Happy Fun Ball is something extraordinarily dangerous that looks innocent. It might destroy the universe, or it might rip a single person to shreds while looking oh so precious. A living version of a Happy Fun Ball is a KillerRabbit. Supertrope to MyLittlePanzer, "toys" that are too dangerous to be toys. May overlap with HiddenWeapons.

Contrast with NerfArm, which is only potentially dangerous because of who uses it, and ImprobableWeaponUser, the one who uses it. Compare with ExcaliburInTheRust, which is also about weapons that don't look like much at first (due to looking old and/or broken), and ShoePhone, gadgets and knickknacks hidden inside innocuous objects. See also LethalJokeItem for the video game equivalent, SuperFunHappyThingOfDoom, and TheNotSoHarmlessPunishment.

Not to be confused with a HyperDestructiveBouncingBall, though it might well be one.



[[folder:Anime & Manga]]
* ''Manga/{{Bleach}}'': [[spoiler: The Hougyoku]] is a simple, tarnished orb when it's first introduced. Aizen even remarks that it's strange that such a simple object could be so powerful.
* ''Manga/InuYasha'': If it's a simple-looking orb you're looking for, look no further than the [[DismantledMacGuffin Shikon no Tama (Jewel of the Four Souls)]], which is the size of a large marble. Sealed within it are the souls of a demonic horde and priestess trapped in an eternal battle. Even a tiny shard of it can make give a demon or human a powerful upgrade, and the first time we see it it's represented as a tacky key-chain. [[spoiler: It's eventually revealed to be the true [[UltimateEvil villain]] of the series, manipulating even [[BigBad Naraku]]]].
* In the Orichalcos arc of ''Anime/YuGiOh'', Joey inherits a card that can fuse with a monster to create never-before-seen equipment cards. During its first use, it creates a winged gold croquet hammer with chibi wings. Turns out it has the power to send all of his opponent's monsters forward in time by a random amount. His opponent is left defenseless, which earns a raw beatdown, and the monsters only come back one by one, allowing the members of the former army to be picked off.
* ''Manga/MedakaBox'': Unzen, an EnfantTerrible KnightTemplar [[YellowSashOfPower high school enforcer]], uses actual rubber balls that are MadeOfExplodium. His [[AxeCrazy sister]] uses less-fun giant metal balls on chains.
* The Legendary Orbs from ''Manga/{{Yaiba}}'' may or may not count, but they're still small, simple glass-like balls which holds great elemental powers within. Expecially the [[ShockAndAwe Raijin Orb]] and the [[BlowYouAway Fujin Orb]]
* Much of the LostTechnology in ''Anime/GalaxyAngel'' invokes this trope.
* In ''Manga/CardcaptorSakura'', one of [[spoiler:Eriol]]'s plots involves turning Sakura's homemade teddy bear into a booby trap.
** The Clow cards, themselves, are [[HappyFunBall Happy Fun Balls]]. They look harmless, but can cause destruction if they're not controlled by a magician.

[[folder:Comic Books]]
* ComicBook/TheJoker resorts to these all the time, when he's not directly using a clown- or comedy motif. Even then, it's pretty common he'll resort to something that actually ''is'' harmless as a fakeout, knowing people will assume the worst anyway.
* In the comic version of ''ComicBook/TheTick,'' one villain incapacitates The Tick with a device called "the Happy Apple".
* The ''Franchise/{{Superman}}'' villain Toyman is basically a professional HappyFunBall manufacturer.
** In the [[WesternAnimation/SupermanTheAnimatedSeries DCAU cartoon]], he once used a ''literal'' happy fun ball, which totalled an armored car.
* The Ultimate Nullifier of the Franchise/MarvelUniverse is about the size and shape of a cell phone, curved on three sides and flat on the fourth, with a couple widdly little protrusions. It could destroy the universe if used right, and will likely destroy the user whether used wrong ''or'' right. Contrast, say, the Infinity Gauntlet, which looks ''exactly'' like the kind of glove you would want for punching gods in the face.
* Richard Corben wrote a short comic called "Top to Bottom" where a children's toy that looks vaguely like a high-tech 3D labyrinth game proves to be a potential world-wrecking device when used unwisely. Borderline terrifying.
* [[MadScientist Brainstorm]] in ''ComicBook/TheTransformersLastStandOfTheWreckers'' has an otherwise inconspicuous briefcase that he says contains a "Malevolent Counterintuitive Pathogen." If anyone but him opens the briefcase, the thing that they least expect will suddenly appear and kill them. [[spoiler: It turns out that this is all a lie- the briefcase is actually linked a bunch of different briefcases that each contain a single piece of a time machine that's specially constructed so as to be immune to the GrandfatherParadox]].
** It doesn't put people off; [[SchmuckBait they open it anyway.]]
* ''ComicStrip/TheFarSide''; A group of gangsters are trying to pry information from a guy who's tied up. The leader says they've tried everything on him except "this little baby we simply call 'Mr. Thingy'."

[[folder:Fan Works]]
* In ''Fallout Equestria: Duck and Cover'', protagonist Atom Smasher carries a nerf gun, which is about as dangerous as you'd expect. Until some traders in need of extra security provide her with a clip of reusable darts enchanted to explode on contact. Given that Atom Smasher has no form of empathy whatsoever (she's intended to reflect the typical Fallout protagonist as played by an immature gamer more interested in killing baddies and finding cool stuff than acting like a decent moral being), this means trouble for everybody around her.

[[folder:Films -- Animated]]
* The "Lok-nar", the evil green sphere in ''WesternAnimation/HeavyMetal'', had a tendency to melt the flesh from the bones of people who happened to touch it, when it wasn't busy animating corpses. Although it ''does'' [[PowerGlows glow]]. That should have been a giveaway.
* In ''Anime/CastleInTheSky'', Sheeta's Laputan grandmother taught her the "Spell of Destruction" as a NurseryRhyme on condition she never use it. Which she inevitably does when duly provoked by the BigBad.

[[folder:Films -- Live-Action]]
* ''Film/ChildsPlay'' is built around this premise, with a serial killer's soul trapped inside a "My Buddy"-esque doll.
* ''Film/{{Transformers}}'' movie: An innocuous-looking radio proved to be the Decepticon Frenzy. And the movieverse version of Frenzy is even more terrifying. When he's eventually knocked in half, what's left of him is enough to, with a bit of shifting as parts, function as a killer robot and hide as [[spoiler:an equally innocent-looking cell phone]]. MoreThanMeetsTheEye, indeed.
* The Continuum Transfunctioner from ''Film/DudeWheresMyCar'', a device with the power to destroy the entire universe, spends most of the film disguised as an ordinary [[spoiler:Rubik's Cube]].
* The puzzle box from ''Franchise/{{Hellraiser}}'' series. Solve it, and eternal pain/pleasure can be yours.
* The climactic battle scene in ''Film/{{Toys}}'' is built around this premise.
* In ''Film/TheKentuckyFriedMovie'', during the kung-fu spoof, the main character sends a seemingly-innocent toy robot into the room. Most of the bad-guy scientists jump out the windows, screaming. "Toy Robot? Ah! A toy robot!" (This is a reference to ''Film/EnterTheDragon'', where Bruce Lee uses a snake to much the same purpose.) When one of the scientists realizes it's just a toy robot, a machine gun pops out of its torso and riddles him with bullets.
** The scientist makes the mistake of ridiculing the toy robot. As it shoots him, it says, "Eat lead, sucker" in a growly voice.
* ''Film/MenInBlack'':
** When J is getting a tour of the office, he sees a small ball floating above a machine. When he touches the ball, it goes careening at high speed through the whole building, smashing windows and knocking people over before K catches it and puts it back, explaining that it had caused the 1977 blackout in New York. The ball was meant for fun, apparently a alien ambassador released it as part of a practical joke likely not realizing it would cause a massive blackout. He thought it was funny as hell.
** To a lesser extent, the Noisy Cricket is one as well. It looks like a child's toy RayGun and is smaller than J's hand ("I feel like I'ma break dis damn thang!"), but it is apparently the most powerful sidearm in the film. According to [[WordOfGod the powers that be]], the Noisy Cricket was originally designed as a concealable weapon, but proved to be easily modified to the magnitude it exhibits in the movie. This was done as a form of hazing for new recruits.
** The Galaxy itself.
* In ''Film/DarkStar'', there is the Happy Fun Beach Ball. An (almost adorable) precursor for the alien in ''Film/{{Alien}}'' and technically a KillerRabbit, but still ...
* In ''Film/DayWatch'', Yegor, a powerful dark magician uses a foil ball as his weapon of choice. Seems harmless, right? Until he uses it to slaughter almost everyone at his birthday party, blind his light equivalent and pretty much destroys all of Moscow.
* In the Korean horror film ''Film/TheRedShoes2005'', the titular shoes look like just an ordinary pair of women's high heeled shoes, but the shoes are haunted by a murderous ghost. Whoever touches or wears the shoes is driven to insanity and murder.
* In ''Film/TheRock'', the opening scene is the hero and a colleague attempting to defuse a child's doll stuffed with [[StuffBlowingUp C4]] and spewing poison gas.
* In the ''Film/TankGirl'' movie, there is a murder-ball - a harmless little metal ball but if you hold press the hidden button, spikes will come out and impale your hand, pretty much putting you out of the rest of the fight. Also can be activated by the sound of "clapping twice".
* Film/JamesBond's watches, pens, shoes, whatever.
* In ''Film/FullMetalJacket'', a Marine picks up a stuffed toy while patrolling a bombed out building in Hue. It's connected to a bomb which blows up, killing him.

* ''Literature/TheLordOfTheRings'':
--> ''One Ring to rule them all, One Ring to find them, One Ring to bring them all and in the darkness bind them''
--> [[LampshadeHanging Strange, that we should suffer so much fear and doubt over so small a thing...]]
** Notable in that in the [[TheVerse film-verse]], the other rings of power are more ornate, while the One Ring is just a simple metal band who's only noticeable feature is the glowing inscription that doesn't even appear most of the time.
* OlderThanFeudalism: PandorasBox (or Jar) from Myth/GreekMythology was designed to look fun, exciting, and interesting. The gods ''wanted'' Epimetheus to open it.
* ''Literature/InterstellarPig'' has "The Piggy", a small grinning pig statue. Cute and harmless-looking, but it's likely to destroy every planet in the universe except the one it's on when the time is right. [[spoiler:Then the Piggy admits it made up that legend and says it only destroys the planet it's ''on''... when it hiccups. Poor piggy, it just wanted friends...]] At the end of the story, the reader learns that the Piggy [[spoiler:is nothing but a recording device that made up the stories to be passed around and record everything. It can't destroy anything -- although it can teleport anything touching it away if it becomes bored.]]
* In Creator/StephenKing's ''Literature/{{Desperation}}'', a hand-held statuette of a poorly-carved coyote, touched by the BigBad, has the adverse effect of causing those in contact with it to give into their savage, normally restrained instincts.
** While turning the savage UpToEleven, from the account of several characters.
* The Culling Song in Creator/ChuckPalahniuk's ''Literature/{{Lullaby}}'' is first found in a book of {{nursery rhyme}}s.
* The first ''Literature/GauntsGhosts'' novel, ''First And Only'', plays with this. In one scene, an enraged Ghost shoots an innocuous but blasphemous Chaos idol to pieces; one of the pieces lodges into another Ghost's skin. A while later, that same Ghost goes insane, starts shooting his comrades, and then mutates into a horrific spawn of Chaos, created by the corruption embedded into the idol's fragments.
* In the Literature/LiadenUniverse books, a Bowli ball is a ball with a gyroscopic randomizer that can send it flying off in random directions. It is used as a combination game and exercise for pilots, and has been known to lead to physical injuries.
* In Louis Sachar's ''[[Literature/WaysideSchool Sideways Stories From Wayside School]]'', Todd brings a [[TastesLikeDiabetes sickeningly adorable]] toy puppy to school for show-n'-tell. The puppy can be manipulated into a terrifying, twisted creature that resembles a werewolf. Joy steals the puppy, not knowing this, and is ''bitten'' by it. The puppy toy doesn't let go.
* ''[[Literature/SwordOfTruth Wizard's First Rule]]'' mentions a curse that turned all red fruit in the region into deadly poison, "[[MoralEventHorizon because children like brightly colored things]]." Richard, who was unaware of this, got (more) death threats from Kahlan by innocently offering her an apple.
* ''Literature/LifeTheUniverseAndEverything'': a harmless-looking cricket ball is a hyperspace bomb that will destroy the entire universe when hit.
* In ''Literature/KeysToTheKingdom'', the most powerful Key is... well, a [[spoiler:simple skeleton key,]] albeit gold-colored & probably glowing impressively.
* In ''Literature/SoonIWillBeInvincible'', the villain Dollface is said to have specialized in innocuous-looking dolls full of powerful miniaturized super technology. Dollface herself is only mentioned, but her work - a gravity manipulating doll to be more precise - is used in [[EvilGenius Doctor]] [[VillainProtagonist Impossible's]] doomsday device to [[spoiler: move the moon at will, controlling the Earth's orbit and thus the temperature of the Earth]].
* Near the beginning of the second ''Literature/{{Fablehaven}}'' book, the kids get sent on a brief FetchQuest to steal a little froglike statue from a fancy house. Seth, being the IdiotHero he is, sees a [[SchmuckBait sign that says "do not feed the frog"]] and decides to feed it out of impulsive {{curiosity|IsACrapshoot}}. Turns out that statue was a demon who'd been TakenForGranite in SleepModeSize, and feeding it brought it to life...
* ''Literature/HarryPotter'':
** This tends to be the outward appearance of [[BigBad Voldemort]]'s [[SoulJar Horcruxes]]. Despite being chosen for their symbolic value, most of those Horcruxes still look fairly innocuous: a tiara, a locket, a ring, a goblet, an old blank journal, etc.
** While not as inherently ''eeeevil'' as Voldemort's Horcruxes, the Elder Wand and Resurrection Stone (two of the three Deathly Hallows) could also be considered examples:
*** The Elder Wand ostensibly allows its owner to win any duel, but its reputation has led many wizards to steal it by murdering whoever owns it at the time (hey, just because you can win any WizardDuel doesn't mean someone else can't simply kill you in your sleep or something). Those who go to the trouble of acquiring such a powerful weapon also tend to be the type of wizards who brag about owning it, and as such they have a very short life expectancy.
*** The Resurrection Stone is dangerous because it can't ''fully'' bring anyone BackFromTheDead, so some users have been DrivenToSuicide once they realise they can never truly reunite with their loved ones unless they themselves die too. On the other hand, the Stone has much more positive effects when used by someone who is already about to die and simply wants comfort from loved ones that they'll be seeing soon anyway.
* In ''Literature/TheMagiciansNephew'', Creator/CSLewis introduces shiny, colourful rings that are used for dimension-jumping and thus can be quite dangerous if you don't know how to use them properly. Later on in their dimension-jumping adventures, the heroes discover a bell with a sign inviting them to either [[SchmuckBait strike the bell or spend the rest of their lives wondering what would've happened if they did]]. As one might expect, when they do strike the bell, the kids end up releasing SealedEvilInACan.

[[folder:Live Action TV]]
* The TropeNamer comes from [[https://www.youtube.com/watch?v=F8zOtZlO52k&list=PLRD2jcKdhMDZ7Ktr3dQU-MqtDZdgxBOP5 the "Happy Fun Ball" sketch]] on ''Series/SaturdayNightLive''. It was a [[MyLittlePanzer kid's toy]] with an [[NoProductSafetyStandards increasingly bizarre disclaimer]], containing warnings such as "[[HyperDestructiveBouncingBall May suddenly accelerate to unsafe speeds]]", "If Happy Fun Ball begins to smoke, seek shelter and cover head", "Happy Fun Ball is being shipped to Saudi Arabia and is being dropped by our troops on Iraq," and the immortal "[[DoNotTauntCthulhu Do not taunt Happy Fun Ball.]]"
** This trope may stick to certain kinds of skin.
** If the outer shell breaks open, avert your eyes from the core and seek shelter immediately.
** Ingredients of Happy Fun Ball include an unknown glowing substance which fell to Earth, presumably from outer space.
** In a later episode, they had an Unfrozen Caveman Lawyer sketch which included Happy Fun Ball among its humorously fictitious sponsors; the plug states that it's "still legal in 16 states"
* ''Series/PowerRangersZeo'' had a cute little dog statue that turned out to be the Midas Hound, an artifact that turned things (and people) to gold at random. It was eventually made larger, gilded the good guys' HumongousMecha, and then became a TransformingMecha of its own!
* ''Series/{{Warehouse 13}}'' gives us the Baylor Dodgeball, a fairly innocuous-looking dodgeball previously used in military training exercises. It bounces under its own power and plays dodgeball with whoever happens to be nearby. Sounds harmless, right? Wrong. First, it "throws" itself only when its victim isn't looking, so there's no chance the person will catch it without a partner. Second, it creates a copy of itself when it connects, and each of those copies acts exactly like the original. That means you'll have dozens of them in no time flat. To stress why this is bad, ''it bludgeoned five soldiers to death'' before it was caught. However, all you have to do is catch one of them and it returns to being a single, inert dodgeball.
** Come to think of it, almost everything in the Warehouse is a happy fun ball/artifact of doom. Some...not so much, like the Mayan idol from the first episode.
* ''Series/DoctorWho'':
** The Autons in the stories [[Recap/DoctorWhoS7E1SpearheadFromSpace "Spearhead from Space"]], [[Recap/DoctorWhoS8E1TerrorOfTheAutons "Terror of the Autons"]] and [[Recap/DoctorWhoS27E1Rose "Rose"]]. When you're facing the [[EldritchAbomination Nestene Consciousness]], [[ParanoiaFuel any plastic object]] is fairly likely to be possessed and [[EverythingTryingToKillYou out to murder you]]. Shop-window mannequins have guns in their arms, plastic flowers try to suffocate people, and [[{{Narm}} someone gets eaten by an armchair]].
** The Weeping Angels, innocent-looking statues of angels with their hands held up to their face as if they're weeping. But when [[ParanoiaFuel nobody's watching]], they spring to life and start killing indiscriminately. That's why you must never [[Recap/DoctorWhoS29E10Blink Blink]]. Oh, and you can't ever [[spoiler:film, draw or otherwise depict them or else the depiction will become one.]] Which leads to FridgeHorror when you realise ''that is exactly what the show itself does''. And if you [[spoiler:look into one's eyes for too long, your visual memory of it will become one and ''murder you from inside your brain''.]]
* ''Series/{{Reaper}}'' had a foam dart gun. The key difference between this gun and any other Nerf gun is that this thing could send anything to Hell. Extra emphasis on the word '''''anything'''''.
* In ''Series/SpaceCases'', a girl brought on board a cute little teddy bear and gave it to a friend. It turns out that the bear is a trap that has a deadly virus on it.
* ''Series/{{Firefly}}'' has Zoe explain why she always cuts her apples up with a knife before eating by telling a story from the war. They were in trench warfare, and were running low on food. Their lack of food came up while talking with the enemies in the other trenches, and shortly afterwards apples started falling into their trenches. Apples with micro-grenades in them.

[[folder:Tabletop Games]]
* ''TabletopGame/DungeonsAndDragons'''s original name should have been '[[EverythingTryingToKillYou Happy Fun Ball: The RPG.]]' Killer statues, killer walls, killer floors, killer bridges, killer ceilings, killer stalactites, killer cloaks, killer bedsheets, and killer water can be found with a glance through the bestiaries. Particularly notable examples include:
** A cursed magical item called [[ExactlyWhatItSaysOnTheTin Scarab of Death]] has the form of a scarab (Egyptian-style brooch) until sustained proximity to a body warms it up, at which point it becomes the other kind of scarab (a flesh-eating beetle) and eats its way to the host's heart.
** Ask any veteran player about the Deck of Many Things. Doom of the multiverse, in an innocuous deck of tarot cards.
** The Necklace of Strangulation is a particularly infamous example, to the point where experienced players won't loot a necklace from a corpse until it's been identified. Indeed, players accustomed to the older editions of the game won't touch ''any'' item that radiates magic until they've had it examined by a sage... and even then, using an unfamiliar item for the first time is a moment of some trepidation.
** There is even a golem type in the Second Edition Monstrous Manual called a "doll golem." It is an enchanted child's toy that can be designed to do various different things. Common roles are either to murder the child in question... or far more amusingly, [[KidWithTheLeash murder anyone attempting to harm said child]].
** ''TabletopGame/{{Ravenloft}}'' has an entire town of this trope called Odiare, where [[spoiler: Evil Pinocchio regularly murders all the adults too old to play with him.]]
** There's also the Bag of Devouring - seems to be an ordinary sack, or possibly a BagOfHolding. It's actually the mouth of an extradimensional EldritchAbomination. Store your magic items in it? You'll be very disappointed when you try to retrieve them. Stick your hand in it? You'd better have a damn good Grapple modifier.
* ''TabletopGame/MageTheAscension's'' final supplement, ''Judgment'', features a scenario concerning the ultimate fate of the universe. To avert the destruction of the natural flow of reality, the players must discover what sort of catastrophe damaged the world to this degree and the weapon that destroyed the universe once before named the First Tool... [[spoiler:which is [[ExactlyWhatItSaysOnTheTin an obsidian hand axe of the simplest form]].[[note]]However, the very final events of the story includes the First Tool becoming reunited with its spiritual counterpart, which is ''the concept of violence''. Once restored, it can destroy the universe once again. Perhaps a subversion?[[/note]]]]
* The card game ''TabletopGame/{{Munchkin}}'' has a card called "Duck of Doom" which immediately drops the affected player by two levels (the point of said game is to reach level 10). The card's caption reads, "You should know better than to pick up a duck in a dungeon".
* West End Games' ''TabletopGame/{{TORG}}'' had "Conjure The Bouncing Hordes Of Doom", found in the supplement "Pixaud's Practical Grimoire". The material component for the spell was a rubber ball with arcane symbols carved into the surface. When the caster tossed the ball while saying "I invoke you", the ball would split into six armed and armored Munchkins with [[ComicBook/NewWarriors Speedball's]] bouncing powers and resistance to kinetic damage, combined with Wolverine's skills with blades AND a gremlin's sheer nastiness.
* In the ''TabletopGame/NewWorldOfDarkness'', you have multiple different kinds of magical items that can appear completely innocuous while actually being a source of terrible power. The most likely ones to take the form of a HappyFunBall are [[TabletopGame/ChangelingTheLost changeling tokens,]] for two reasons: first, tokens are concealed by a [[{{Glamour}} Mask]] so as to appear completely innocuous, and second, they're the easiest for a mortal to activate (accidentally or otherwise). Of course, doing so without paying [[{{Mana}} Glamour]] means that you're going to invoke its [[BeCarefulWhatYouWishFor Catch...]]
** As an example, the Blood Pennon just looks like a strip of sackcloth tied to a stick. Wave it around, however, and you can give yourself and all your allies an extra boost of combat power. Activate it without paying the Glamour cost, however, and it'll leave you drained afterwards... and it'll alert the [[TheFairFolk Gentry]] as to your presence.

[[folder:Video Games]]
* Square-Enix' video games are filled with "weapons" that are [[ImprobableWeaponUser otherwise harmless objects]]. The trend started in ''VideoGame/FinalFantasyIII'' with harps, books and bells; ''VideoGame/FinalFantasyVI'' added the paintbrush, dice, and cards; ''VideoGame/FinalFantasyVII'' contributed the megaphone and comb; ''VideoGame/FinalFantasyIX'' had forks (really big forks, but still...); and ''VideoGame/FinalFantasyX'' contained dolls and blitzballs (basically lumpy soccer balls). The ''VideoGame/DragonQuest'' series gave you the option of using items such as tarot cards or an abacus to attack.
** Have you ever been smacked in the head by a football at close range? That ''hurts''.
** Those blitzballs have to be freaking heavy to stay both stay underwater and move like they do when someone takes a shot, their value as weapons are somewhat understandable with some logic.
** Don't forget about the strongest optional boss in ''VideoGame/FinalFantasyIX'', Ozma. It is a giant floating ball that spins...and casts Meteor, among other things.
*** The idea is that summons in the game are [[ClapYourHandsIfYouBelieve given form by the people who believe in them]]. Ozma is "the forgotten summon", hence it's lost any shape it once had and become a blob of raw power.
** Books are weird. In ''VideoGame/FinalFantasyIII'' you simply bop enemies on the head with them. In ''VideoGame/FinalFantasyTactics'' it's a ranged weapon where you read a paragraph or two and your target [[BrownNote flinches in pain]].
** There's a literal one in ''VideoGame/FinalFantasyVI''. The superball item deals a fair bit of damage when thrown.
** ''Another'' literal example is the recurring Mover enemy. Despite appearing as little red spheres with eyes, they tend to be among the most powerful regular enemies, coming in groups of three to facilitate their devastating "[[CombinationAttack Delta Attack]]". On the other hand, the rewards if you ''do'' defeat them are [[MetalSlime well worth the trouble]].
* ''VideoGame/DwarfFortress'' is FILLED with these. The throwing mechanics are so broken, throwing laundry around will kill all involved, while passing Necromancers will often create an army of walking Fluffy Wambler corpses just to piss you off. And then there are the Giant Sponges - with no nervous system, the only thing they can feel is ANGER.
* The strategy/RPG ''VideoGame/VandalHearts II'' has, in addition to swords, spears, et cetera, an entire class of "oddball" weapons like baseball bats, scythes, and so forth. Most of them are genuinely threatening, if weird...until you get the "Evil Doll," which is a simple children's doll. Wearing a dress. Not only is it one of the most powerful weapons in the game (characters attack by holding the doll in front of them by the head; it shakes once and enemies die, complete with huge gouts of blood), but it teaches its holder a spell that ''sets your entire party on fire'', bringing horrible death to allies and enemies alike.
* In ''VideoGame/PlanescapeTorment'', one of the player's past incarnations kept a journal disguised as a pretty, dodecahedron-shaped puzzle box. The puzzle box was loaded with blades that slit a user's wrist, canisters that unleashed the fantasy equivalent of nerve gas, and other delightful traps for the would-be diary snooper. Imagine a Rubik's Dodecahedron that punished you lethally when you made a move that did not get you closer to solving it and had no visual clues to tell you when you were going the right way. Since you play an immortal with massive regenerative abilities, you are the only one who can open it.
* Parodied in ''VideoGame/{{Portal}}'': ''The Enrichment Center reminds you that the [[CompanionCube Weighted Companion Cube]] will never threaten to stab you and, in fact, cannot speak.''
** And then played with in a mod where it will, in fact, stab you.
*** But, to be fair, [[ExactWords it doesn't threaten you first]].
** Given the chance, it seems that everything produced by Aperture Science will try to kill you. Especially if it can be found in The Enrichment Center.
-->'''Cave Johnson''': Oh, in case you got covered in that repulsion gel, here's some advice that the lab boys gave me: Do ''not'' get covered in the repulsion gel. We haven't entirely nailed down what element it is, yet, but I'll tell you this, it's a lively one, and it does not like the [[BodyHorror human skeleton]].
* The Familiar Spell in ''Ironsword'' summons a tiny little happy face that flies around and [[TakenForGranite turns enemies into coins.]] One can only ''hope'' that this process is lethal, lest it become a case of AndIMustScream for the unfortunate wildlife.
* The Flak Cannon from the ''VideoGame/{{Unreal}}'' series fires giant explosive shells with a friendly looking yellow smiley face on the front.
** ''VideoGame/UnrealTournament2004'' displays the message "Player A played with Player B's happy fun ball..." whenever someone killed another player with the Grenade Launcher.
** "Happy Fun Ball" is also the FanNickname of the bouncing, giggling, spherical, smiley-face adorned Proximity Mines in the ChaosUT mod, included with the Game of the Year Edition of the original UT.
* The Superheros ''VideoGame/{{Quake}}'' mod had this as a selectable power. It was activated on the player's death, which would be followed by a handful of bouncing yellow happy-face spheres bursting from the body, bouncing and swooping with [[EvilLaugh diabolical laughter]], and exploding lethally on all nearby opponents (and sometimes allies.)
* One of ''VideoGame/TotalOverdose'''s special attacks is a pinata. When thrown all enemies are lured running to it with giddy excitement. Its confetti-showering explosion is instantly deadly.
* In ''VideoGame/{{Persona 3}}'',, there is a weapon called the "Toy Bow", a plastic bow that fires suction-cup toy arrows. During the part of the game where you get it, it's very powerful and, unlike nearly every other bow, is very accurate. However, its usefulness swiftly wanes as the game continues.
* In ''VideoGame/RakugakiShowtime'' you have the Smiley Ball -- a doodly smiley face you throw at people. Throw it at enough people and it gets angrier and angrier looking -- until it turns rainbow colored with a look of awe on its face, and becomes the most powerful item in the game.
* ''VideoGame/IWannaBeTheGuy'' has Delicious Fruit, whose rationale for crushing you (sometimes even flying upwards) is that they're "more like giant cherries" than apples.
* ''VideoGame/{{Worms}}'' has... well, there's the Banana Bomb, which [[StuffBlowingUp explodes spectacularly]]; the Super Banana Bomb, which [[KillItWithFire explodes]] ''[[UpToEleven more]]'' [[NukeEm spectacularly]]; the Salvation Army, which [[RuleOfThree explodes spectacularly]]; [[BaaBomb various animals]], which [[OverlyLongGag explode spectacularly]]; and the MB Bomb, a large balloon, which... yeah.
** [[http://www.liero.be/ Liero]], a [[http://lierohell.free.fr/winxp_vista.html real-time remake of Worms 1]] in which you have lives as opposed to multiple worms, goes SerialEscalation as it allows fan-made weapons to be imported. For obvious reasons the ''TabletopGame/Warhammer40000'' and ''Franchise/{{Dune}}'' mods trump the above, but one particular 'strange weapon collection' has something called the [[ExactlyWhatItSaysOnTheTin Crazy Cannon]] which is a bazooka that fires a small slow-moving orb. Just as you finish thinking "That was lame" it flips out and begins bouncing around the screen like Ball Kirby, WHILE [[MacrossMissileMassacre rapidly spamming rockets]] at max charge speed for [[MoreDakka a FULL MINUTE]]. 90% of the time, using this [[LethalJokeWeapon clears out all land on the stage and makes everyone die repeatedly]]. Also will absolutely CRUSH the processor of any computer made before 2001. Thankfully recharge time is so long that it will almost never recharge during a match, so it appears to be meant as a [[TakingYouWithMe screw you]] option. If your ninja rope can reach the ceiling however, it's actually possible to survive it with some bullet hell dodging skills. Oh, what I said before? Roll that up to 2003 if you pick one for all 5 weapon slots. [[EvilLaugh Bwuahahahahaha]]!
* ''Shadow Madness'' had an item that was tricky to find, requiring a couple of minigames to access. When you found this item, [[MeaningfulName Pandora's Cauldron]], its only description was "Do not use. EVER!" [[SchmuckBait Actually using the item anyway]] led to the longest video {{cutscene}} in the game and a "GameOver (Insert Coin)" message.
* ''VideoGame/{{Fallout 3}}'' has "rigged baby carriages," which appear to be normal baby carriages from a distance. However, get too close and a distorted lullaby plays, along with the rather creepy sound of a baby crying. Then the carriage [[OverlyLongGag explodes spectacularly.]]
** The Rock-It-Launcher is a cannon that fires common cluttered junk with enough force for '''a teddy bear to mutilate super mutants'''.
** And the Euclid Finder in ''VideoGame/FalloutNewVegas'', seemingly a harmless toy gun... which is in fact a target finder for a ''KillSat''. If you decide to arm said satellite ''before'' retrieving the Finder from its current owner - a small child using it, predictably, as a toy - one of your companions may remark how ''incredibly'' lucky you were that the safety was still on.
* Subverted in ''VideoGame/WorldOfWarcraft'' with the Happy Fun Rock. You toss it to other players...and it does nothing. Really. No, really.
* ''VideoGame/GuildWars2'': The Quip and The Dreamer are a pistol and bow that leave pretty rainbow trails and shoot confetti and unicorns, respectively. They'really also Legendary-level weapons for a ''reason'', as their stats and damage levels are ridiculous.
* ''VideoGame/NetHack'':
** ''Dungeons and Dragons'' Amulet of Strangulation shows up but it doesn't stand out quite as much; this is because you get used to being paranoid about ''[[EverythingTryingToKillYou everything]]'' [[DeathWorld in NetHack]].
** There are musical instruments that cause large earthquakes and shoot fire and ice beams (even better than wands that do the same things, though much more rare). Anything can be equipped as a weapon but it won't hurt your opponent unless it performs damage calculations (with the exception of the cream pie: it goes "splat" if you try to hit something with it, [[PieInTheFace blinding things with eyes]]). There's also the loadstone; small and innocuous, one of four types of grey stone items in the game, ''back-breakingly heavy and usually [[StuckItems cursed]]'' if [[EverythingTryingToKillYou you]] accidentally pick it up.
** Tinned food is usually a good choice of sustenance, but the contents can be almost any creature you can encounter in the game, and eating some monsters isn't always advisable. Szechuan-style [[TakenForGranite cockatrice]] is something you only try once.
* ''VideoGame/GuiltyGear'' features the infamous [[UnsettlingGenderreveal Bridget]]. Less famous is the fact that Bridget's weapons included a yo-yo and a teddy bear, both capable of sprouting sawblades or shooting out jets of flames.
* In ''VideoGame/{{Disgaea 3|AbsenceOfJustice}}'', Princess Sapphire finds a [[SchmuckBait cutesy teddy bear]]... laced with poison. [[TakingTheBullet Almaz grabs it instead.]]
* ''VideoGame/{{MDK}}'' featured the ''World's Most Interesting Bomb.''
* In the backstory of ''VideoGame/TheSeventhGuest'', villain Stauf is a toymaker who ''specializes'' in Happy Fun Balls. His beautiful toys are snapped up by local children, all of whom become mysteriously and fatally ill...so he can fulfill his half of a DealWithTheDevil and steal their souls.
* In ''VideoGame/TheLastExpress'', [[spoiler:the Firebird seems to just be a golden jewelled egg with the curious ability to transform into a falcon that can sing when you play a whistle. What you don't know is that, if you do this at night, it becomes a deadly weapon...]]
* In ''VideoGame/MetroidOtherM'' the Little Birdie is a cute little white bird-looking creature, first seen unsuccessfully and humorously attempting to get on top of a large fruit, but turns out to be [[spoiler: the juvenile form of a clone of Ridley, the Space Pirate general who decimated her home planet of K-2L, and had been kept as a pet by oblivious researchers until it dismembered one and escaped.]] Wow. Although the more perceptive players (and Samus herself) will suspect that it's not as it seems, especially with regard to how it appears to apparate behind Samus before she goes through the door into the Navigation Room, staring at her with its beady little eyes.
* In the [[VideoGame/DadSeries Dadgame]], defeating [[BonusBoss Mecha]] [[ThatOneBoss Death]] earns you... a ''[[LethalJokeWeapon cat launcher]]''. Which deals damage. And is the longest range weapon of the game, especially if you charge it up - the cat gets sent ''flying across the screen''.
* ''VideoGame/OgreBattle'' has Doll Mages / Masters who, while capable of throwing the dangerous Acid spell from the rear of the formation, use a marionette to attack from the front row.
* In ''VideoGame/ArcanumOfSteamworksAndMagickObscura'', the animal summoned with the Call Beast spell changes depending on your Magic Aptitude. If you have 100 then you summon a Vorpal Bunny. It looks like a regular white bunny ... except it's a level 40 creature in a game where the level cap is 50 and it has master level melee skill. When it kills someone they are always dismembered in the process.

[[folder:Web Comics]]
* ''[[Webcomic/WalkyVerse It's Walky!]]'' has the Power Booster Rod, which looks like a large tree branch, but could potentially destroy the entire universe.
* Largo's "Cool Thing" from ''Webcomic/MegaTokyo'' looks like a toy ball with lights and buttons.
** Note that the Cool Thing (TM) has not been established as any sort of universe-destroying artefact of doom, though it does emit alarmingly loud noises when provoked (what Largo does to the Thing can in no way be called "use").
* ''Webcomic/TheOrderOfTheStick'': [[http://www.giantitp.com/comics/oots0448.html "Follow the bouncing ball, children!"]]
* The Planet Devourer from ''Webcomic/CaseyAndAndy''.
* The unimpressive little [[http://www.airshipentertainment.com/buckcomic.php?date=20070929 box]] from ''ComicBook/{{Buck Godot|Zap Gun for Hire}}''. Also, possibly [[SpeechImpairedAnimal the Winslow]]. "[[CatchPhrase Hi!]]"
* In ''Webcomic/GirlGenius'', [[MalevolentArchitecture Castle Heterodyne]] houses the "Fun-Sized Mobile Agony and Death Dispensers", bison-sized, murderous cat-like clockworks. When the castle is fully functional, it has complete control of them. When the Castle ''isn't'' fully functional, then you'd best hope the Fun-Sized Dispensers are confined to one room and don't know you're around.
** The Castle also has a [[http://www.girlgeniusonline.com/comic.php?date=20090724 "Happy Fun Ball of Death"]] (yes, that ''is'' it's official name) on a [[BigLabyrinthineBuilding week-long rotation]] - these sorts of names seem to be a running theme for the old Heterodynes.
* Hannelore in ''Webcomic/QuestionableContent'' has a roomba. At first the most heinous thing it does is threaten the standing of [[RobotBuddy Winslow]]. Then Marten comforts Hanners. The thing somehow ''pulls a knife'', believing Marten was making a move on "its woman".
** Later, its PowerLevel climbs to '''[[http://questionablecontent.net/view.php?comic=1057 over nine thousand!!]]'' Then it [[http://questionablecontent.net/view.php?comic=1557 evolves]], goes searching for [[CoitusEnsues true love]]. [[http://questionablecontent.net/view.php?comic=1594 And apparently finds it.]] Once they outnumber us, we're ''[[http://questionablecontent.net./view.php?comic=1643 doomed]]''.
* ''Webcomic/PlanetZebeth'' has the "Super Happy fun slide": Enemies slide down into a hidden deep-frier, and are then served as meals in the adjacent bar.
* ''Luke Surl'' managed to turn a shredder into this [[http://www.lukesurl.com/archives/2284 just by explaining labels on it]] (see also AltText).
--> Any attempt to destroy the shredder by aerial bombardment would be futile.
* In ''WebComic/RustyAndCo'' Presti combines several apparently harmless items (including a funnel and a Bag of Tricks) together to form a deadly "Badger Launcher".

[[folder:Web Original]]
* Tom Foolery, from the ''Roleplay/GlobalGuardiansPBEMUniverse'' is an {{Expy}} of both the Joker and the Toyman. While he's a capable hand-to-hand fighter and a nimble acrobat, his greatest weapons include things like yo-yos with razor sharp jacks, robotic, machine-gun toting teddy bears, model airplanes carrying micro-missiles, and a bouncy explosive ball that he even calls HappyFunBall.
* As expected, a lot of the stuff contained by the Wiki/SCPFoundation, such as [[http://scp-wiki.wikidot.com/scp-018 SCP-018]].
** All but invoked by [=SCP=]-846.
** Lampshaded in "Things Dr. Bright Is Not Allowed To Do At The Foundation": SCP-018 is not to be taunted!
*** And if it isn't a Happy Fun Ball, SCP-914 can make it into one. One notable example being an enhanced super ball the killed several people, destroyed entire wings of the site, and was last spotted orbiting Mars.
* At the SuperheroSchool Whateley Academy in the Literature/WhateleyUniverse, there's a deviser codenamed Knick-Knack who makes these all the time. We've seen a fake 'Harry Potter' wand which has been turned into a real laser weapon, suspicious snow globes, lava lamps that are now attack devices a la 'Rover' of ''Series/ThePrisoner'', and a conch shell with ''something'' inside it that you don't want to know about.
** Jade Sinclair, AKA 'Generator', has a penchant for these sorts of things, like a ''Franchise/HelloKitty'' compact which contains insanely sharp spinning knives. Then there's Bunny Cormack, or 'Bugs', who makes pastel eggs which explode viciously when they break. Basically, if you're at Whateley, don't mess with anything the devisers come up with.
* In the "WebAnimation/HappyTreeFriends" episode "A Vicious Cycle" Flippy is killed by a bolt of lightning and his soul inhabits Cub's tricycle which he uses to kill those he was trying to kill before his unexpected death.

[[folder:Western Animation]]
* In an episode of the ''WesternAnimation/EarthwormJim'' cartoon, a page containing a spell that could destroy the universe was, due to a grievous printer's error, placed in a children's pop-up book that happened to be owned by the protagonist.
** In another, the most powerful force of destruction in the universe was locked away in a snow globe.
* In ''WesternAnimation/{{Ben 10}},'' the Omnitrix appears to most to be a regular wristwatch. It's a ClingyMacGuffin that calls up obscenely powerful monster forms for the wearer.
* In the cartoon version of ''WesternAnimation/TheTick'':
** The Tick is incapacitated by "The World's Comfiest Chair". (No one expects a reference to ''Series/MontyPythonsFlyingCircus'' in a children's animated series...)
** Subverted when the Tick encounters the Infinity Ball (which looks just like an 8-ball), supposedly an "ultimate weapon". It bumped into the Tick and fell.
--> "Where I come from, we hit these into pockets with sticks." "GASP!" "And we have higher numbers, too!"
* ''WesternAnimation/DuckTales1987'' had an item that was similar to the ''Franchise/PowerRangers'' example above, but infinitely worse: a small goose idol that turned things into gold... at first. Then it started a chain reaction that was ''turning the entire world into gold''. The golden goose was held in a magic fountain that neutralized its gold-turning powers. If the goose was taken and kept away from the fountain's water for too long, it will awaken and turn things [[TakenForGranite and people]] to gold on its own accord. And if allowed to remain awakened for too long, the goose's gold-turning powers escape from its body, leaving it as a normal goose, while the powers proceed to turn the world to gold, referred to as [[ApocalypseHow "The Golden Death"]]. The only way to stop this scenario, obviously, is to return the goose to the fountain.
* ''WesternAnimation/TheSimpsons'':
** In one episode Prof. Frink discusses the possibility of turning a souvenir he found at the airport (a motorized ball with a toy weasel attached) into a weapon. At the end of the episode, the toy rolls onscreen; Frink panics but Homer, convinced it's just a "cute little weasel", goes to pick it up. Cut to a "The End" title card as we hear zapping sounds and Homer screaming in pain.
** In a slightly more literal example, a ''Treehouse of Horror'' segment featured dolphins violently rising up against humans. One of the weapons that they used was a red utility ball. They were surprisingly effective, as Kent Brockman will attest.
* The ''WesternAnimation/{{Futurama}}'' episode "Mother's Day" had a younger Professor Farnsworth invent the adorable children's toy "Q.T. [=McWhiskers=]" for Mom's Friendly Robot Company. Mom subsequently turned the toy into a laser-firing death machine for the intergalactic arms market.
* ''WesternAnimation/BatmanTheAnimatedSeries'':
** The villain Baby Doll has a variety of deadly weapons disguised as toys, including a doll with a gun inside it and explosive bouncy balls.
** Joker occasionally uses these as well.
*** His trademark lapel flower usually contains acid, and he's been known to use marble grenades.
*** Also, his equally signature toy gun with a "BANG!" sign, which then fires anyway. [[spoiler:This is eventually [[HoistByHisOwnPetard used to kill him]] in a flashback in ''WesternAnimation/BatmanBeyond''.]]
*** Don't forget his lethal ElectricJoyBuzzer. This one was turned against him in the ''WesternAnimation/StaticShock'' {{crossover}} when Static easily absorbed the electricity - [[ShockAndAwe then gave it back]].
* An episode of ''WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius'' had Jimmy's father working as a toy inventor-- between Jimmy [[TimTaylorTechnology "tweaking"]] his dad's gizmos (such as adding real lasers), and then one of them (a doll/tank hybrid) being weaponized and turned gigantic by Jimmy's renegade [[{{Nanomachines}} Nanobots]]. [[HilarityEnsues Hilarity, and large repair bills, ensue.]]
* ''WesternAnimation/TheVentureBrothers'' has [[DramaticPause ...]]''The Nozzle'', an innocuous yet fear-inspiring doodad that not even its owners understand the purpose of. Its engagement is accompanied by an unsettling mechanical voice warning the patient; "Do not move while ...''The Nozzle'' is engaging. Moving will interrupt calibration of ...''The Nozzle''. Please do not look away while ...''The Nozzle'' is calibrating."
* Quackerjack in ''WesternAnimation/DarkwingDuck'' tends to use these. Hell, Mr. Banana Brain is the only mundane toy of the lot, and he's still got some pretty distressing ideas. Which become even more distressing when he is [[SoulJar possessed]] by Paddywhack.
* Perhaps in a direct reference to the [[Series/SaturdayNightLive SNL sketch]], ''WesternAnimation/SupermanTheAnimatedSeries'' villain [[PsychopathicManchild The Toyman]] uses a happy fun ball on some {{Mooks}} that eventually moved so fast, and hits so hard that it dented ''the armored car'' it bounced against. And being Toyman, most of his gimmicks are Happy Fun Balls.
-->"Uh, maybe you should read the warning? Dopey Dough is a ''lethal biogenic organism''. Contact with the skin can prove ''fatal''. It won't stop growing until it ''asphyxiates its host''. [[ArsonMurderAndJaywalking NOT for children under three.]]"
* In the GrandFinale of ''[[WesternAnimation/JusticeLeague Justice League Unlimited]]'', Toyman is surrounded by Parademons. He promptly shoots them with...suction cups from his Nerf gun. One beat later they explode. (No, not the suction cups...)
* ''WesternAnimation/AquaTeenHungerForce'' featured the Broodwich, a delicious sandwich (in spite of having no bacon). However, eating it will forever condemn you to a hellish dimension.
* ''WesternAnimation/RobotChicken'' featured the [[https://www.youtube.com/watch?v=s9876IczneY Phyllis Diller Spray & Play,]] a bunch of hoses coming out of a plastic Phyllis Diller head, which quickly killed all the kids playing with it.
* There is a long history of Transformers who turn into seemingly-harmless objects, but the most famous would probably be Soundwave and his minions from [[WesternAnimation/TheTransformers the original series]], who transform into a tape player and cassettes. The practical upshoot being that Soundwave transforms from something you'd put in your pocket without a second thought to a giant war machine who can deploy his own personal army from his chest. Thankfully, he has a good counterpart, Blaster, who turns into a boombox and has his own cassette army.
* In the ''WesternAnimation/RocketMonkeys'' episode "B.A.L.L." the monkeys are tasked with delivering the eponymous B.A.L.L. (Ballistic and Lethally Loaded), which is an actual ball. They have to refrain from playing with it or it will explode.

* [[http://www.youtube.com/watch?v=_aXujOsWJkY This]] ''WebVideo/AMVHell'' clip taken from a ''Franchise/{{Transformers}}'' movie. It's even an actual (though giant) ball.

[[folder:Real Life]]
* Land mines often look dangerously toy-like: they're made of plastic with rubber stokers, to avoid detection, and air-dropped mines have fins to aid dispersal. Both sides in the 1980s Afghan war used air-dropped anti-personnel mines, and each accused the other of making their mines look like toys on purpose.
* Bomblets from US cluster bombs are bright-yellow ovals, to maximize visibility. Until November 2001, so were US [[https://en.wikipedia.org/wiki/Humanitarian_daily_ration Humanitarian Daily Ration]]s, also to maximize visibility. Until the 2001 Afghan war, the US had never had occasion to drop cluster bombs and humanitarian rations in the same place; once that war got underway, people noticed the problem (to quote Creator/RobinWilliams, "Now you're playing Survivor, the ''real'' game"), and the Pentagon re-colored the Humanitarian Daily Ration to salmon-pink.
* From the [[http://skippyslist.com/list/ 213 things Skippy is no longer allowed to do in the U.S. Army]], "Claymore mines are not filled with yummy candy and it is wrong to tell new soldiers that they are."
* Booby-trap bombs are intentionally made to look harmless, or attract positive attention. The Nazis had exploding chocolate bars ("flyer's chocolate", quality German chocolate laced with quality German meth, had quite a reputation), and often abandoned stylish helmets with stylish live grenades inside; the Japanese booby-trapped bottles of sake, but mostly preferred covered pits with pungi sticks; the Vietcong left their flags flying defiantly in positions they abandoned, with explosives on the flagpoles. Other perennial booby-trap designs include ration packs (especially the enemy's) and envelopes, and reportedly the VC had bombs that looked like bathroom scales.
* Lawn darts. These foot-long mini-javelins with fins were supposed to be lobbed into the air in an attempt to hit target circles on laid on the ground. This was much like playing horseshoes with throwing knives, since the metal-tipped toys were essentially identical to Irish war darts. After forty or more years on the market, they were finally discontinued in the 1990s because of the obvious safety issues (and a string of ''hundreds'' of injuries per year).
** Older sets are still out there, of course, and other countries might not ban them (of course, many other countries might have had the sense not to make the damn things in the first place). Also, you can buy the parts legally in the U.S. and still assemble them yourself. There are also all-plastic models which can be sold in both countries - still hurt if you throw them at people, but no more likely to cause bleeding than any other weighted plastic toy you can buy legally.
*** Human nature also plays a part. One Cracked.com article also points out that lawn darts are almost completely safe-if you play by the rules. It goes on to point out (needlessly if you know anything about children) that few were the children who were actually liable to do so for long, and it was only a matter of time before some bright spark decided to try catching it with their teeth.
** [[TabletopGame/KillerBunniesAndTheQuestForTheMagicCarrot "One of your bunnies is impaled by a stray lawn dart during a family outing!"]]
** Creator/JeffFoxworthy included lawn darts in his set about dangerous toys that aren't allowed anymore. He also mentioned B.B. guns, wood-burning kits, and chemistry sets.
-->'''Foxworthy:''' [Lawn darts] didn't come with instructions, they just came in a box of eight! We used to take them out and just throw them straight up in the air! You catch one of those with your head, you're getting coloring books for Christmas the rest of your life.
* How about the [[http://www.brightontoymuseum.co.uk/info/Metropolitan_underground_locomotive,_110V_%28Hornby%29 original Hornby "high voltage" Electric Train Set]]? 110V of alternating current running through the model track is a bit more than "ouchy" if you put your finger on the rail. The first version even had a rheostatic controller with a switch sweeping across completely unprotected metal contacts. Threats of legal action led Hornby to first redesign the controller to cover up the contacts, and then reduce the voltage to a much safer level.
* A horrific example: In 1999, 39 people were literally cremated in one of the worst tunnel fires in history in the Mont Blanc tunnel in France. The main fuel for the fire? Ordinary margarine. If you get the stuff to ignite, it burns as hot as diesel fuel; vegetable oil, one of its key ingredients, can actually be mixed in with diesel and run an engine.
** Not helped by the truck's other cargo, flour, which as mentioned just below, is quite explosive when aerosolized.
** In 2013, Norway had a major tunnel closed for weeks after 27 tons of caramelized brown goat cheese burned for five days. No injuries were reported. Still trying to get out the burnt cheese and fondue smell.
** Paper is a major fire hazard. It is both easy to ignite and burns with extreme heat. Theses properties allowed it to melt the steel beams inside the Twin Towers.
* The [[https://en.wikipedia.org/wiki/Great_Molasses_Flood Great Molasses Tidal Wave]] in Boston in 1919.
** In that vein, the [[https://en.wikipedia.org/wiki/London_Beer_Flood London Beer Flood]] of 1814.
** The Banbury Custard Explosion of 1981.
*** No, they're not making any of these up. Though thankfully in the custard explosion, no one was killed. The same can't be said for the previous two.
* In a similar vein, aerosolized flour is a huge explosion hazard.
** As is aerosolized sugar, as we learned so painfully after the [[http://en.wikipedia.org/wiki/2008_Georgia_sugar_refinery_explosion 2008 Georgia sugar refinery explosion]].[[note]]A [[LiteralMetaphor literal]] SugarApocalypse![[/note]] Indeed, it's ''worse'' than aerosolized flour--flour doesn't melt into a sticky, smoldering mess when you subject it to high heat. It's sometimes said that molten sugar is one of the most dangerous things a cook will handle in their careers. The reason for that is because while boiling water will roll off your skin, boiling sugar will adhere to your skin like glue and continue burning you, which can actually lead to some truly gruesome injuries.
** A surprising range of otherwise innocuous substances are fire or explosive hazards when reduced to a fine powder. Coal dust is a major concern for miners for this reason, and powdered aluminum is used in certain explosives.
*** Series/{{Mythbusters}} used non-dairy powdered creamer in an attempt to amp up the flour burning cannon design they replicated from a web video. They later confessed that the insane fireball they created made them fear for their lives.
*** Any kind of organically based dust--flour, sugar, coal, powdered wood, starch, etcetera--is highly explosive when suspended in the air. And these kinds of explosions inspired the creation of thermobaric weapons.
* A lot of poisons, sadly. Poisonious plants and mushrooms often don't look as dangerous as they are, or they are fancy coloured and especially children can think they look pretty. The poison itself often hasn't any a taste, so people don't realise when they're eating something poisonous.
** One of the worst examples is the aptly-named "Destroying Angel". The name refers to several snow-white mushrooms, all of which contain fatal poison and are in fact the main source of mushroom poison-related deaths globally. The symptoms from it are also horrifying.
* As can a lot of poisonous animals. Species like the [[https://en.wikipedia.org/wiki/Granular_poison_frog Granular Poison Frog]] and the [[https://www.thailandsnakes.com/venomous/front-fanged/blue-malaysian-coral-snake-venomous-deadly/ Blue Malaysian Coral Snake]] are deceptively small and beautifully colored, but the former is deadly to the touch and the latter's bite can kill in 15 minutes. Perhaps the worst of all, though is the small and cute blue-ringed octopus... whose neurotoxin-laced-bite is 1200 times stronger than cyanide and currently has no antivenom. Compounding this, they each carry enough venom to kill twenty-plus adult humans, and their bite is often painless -- meaning that until respiratory failure kicks in, a victim might not even know they have been harmed, nevermind that they are virtually guaranteed to die within minutes. Their interesting pattern of changing circles is meant as a deterrent for predators, but combined with its small stature (often less than 8 inches tip-to-tip) only seeks to reinforce the cuteness and perceived harmlessness.
