->"''Little boy, you okay- OHHH... Oh my... he's not okay, he [[YourHeadAsplode lost his head]]. Oh God, what the fuck is wrong with this GAME?''"
-->-- '''LetsPlay/UberHaxorNova''', in his [[http://www.youtube.com/watch?v=U1lG7HBehjs first session]] out of 198.

A Flash browser game created in 2010 by Jim Bonacci that is like many other racing/driving browser games, except all the characters are MadeOfPlasticine and ride in vehicles with little to no protection aside from maybe a helmet.

Current List of Characters:
* Wheelchair Guy: A guy who appears like a stereotypical homeless person, with patched-up clothing, missing teeth, and a beard. He rides in a wheelchair which inexplicably features a rocket booster.
* Segway Guy: A guy in a suit that rides a [[strike:[[{{Malaproper}} subway]]]] segway that has the ability to jump and always stays straight up.
* [[BumblingDad Irresponsible Dad]]: Pictured at right, a man who rides a bicycle with (presumably) his young son riding on the back. [[EnsembleDarkhorse Also seems to be the most popular character.]] Often called [[FanNickname "Bike Guy"]] to fit the ThemeNaming of other characters. Can eject his son as an extra effort to get to the goal, or [[VideoGameCrueltyPotential to trigger traps]]
* Effective Shopper: An obese woman who rides an electric shopping cart with her groceries inside. Her weight makes her easy to tip over.
* Moped Couple: A man riding a moped with his girlfriend/wife riding behind him. The moped features a speed boost that briefly increases the speed by a lot, but of course not as much as Wheelchair Guy's rocket.
* Lawnmower Man: A black man riding a mower. Anything that gets run over gets shredded and swallowed up by the blades. Probably the most violent character so far.
* Explorer Guy: Largely based on ''Franchise/IndianaJones'', he rides a heavy mine cart. Can link up and ride on rails by holding the space bar.
* Santa Claus: Sits on a sleigh, pulled by two elves. The first character with three people and without wheels. Can fly by holding the space bar.
* Pogostick Man: A man riding a pogostick wearing kneepads and elbowpads. Can jump higher and farther by pressing or holding the space bar. Voiced by LetsPlay/UberHaxorNova
* Irresponsible Mom: A mother who, similar to Irresponsible Dad, rides a bicycle with her children, but this time, one child is in a basket at the front, while the second is in a extension of the bicycle that's easy to break off...
* Helicopter Man: An obese man in a personal helicopter. There is a magnet (turned on and off with the space bar, moved up and down with Shift and Ctrl) between the landing struts that can be used to pick up objects, including other characters

----
!!This game provides examples of:
* AnalProbing: The "[[ExactlyWhatItSaysOnTheTin Probing Bay]]" in The Astro Avenger.
* AnnoyingArrows
* AnyoneCanDie
* ArtEvolution: Version 1.6 adds realistic gore to the mix. Now the blood looks more like blood instead of red confetti.
* ArsonMurderAndJaywalking: One user-created level "The Torture Gallery" featured a variety of horrific tortures, with the last one being a kid getting spanked.
** Some of the Saw levels fit under this trope. One of these levels had a woman who raped your child, a guy who stole all of your money, and [[DisproportionateRetribution a man who used your toilet without permission.]]
* AscendedFanboy: LetsPlay/UberHaxorNova, for voicing the Pogo Stick Man.
* BadSanta/ BadBoss: Santa whips two hapless elves so they pull his sleigh. He even laughs (with his well-known "Ho ho ho!") when an elf gets smashed into bloody paste by the sleigh!
* BigOMG: Irresponsible Dad will cry out "Oh God!" whenever he breaks his spine.
* BloodyHilarious: If you like that sort of thing.
* BodyHorror: Oh goodness, the ways the harpoon runs can disfigure you.
* BoomHeadshot: One way to die. There's a sweetspot in each character's head that, if in contact with a blade, will kill you instantly.
* BumblingDad: The Irresponsible Dad, natch.
* ButtMonkey: Timmy (and occasionally the woman on the moped and Santa's elves) are often either abused for hilarity, or used merely to set off traps which may kill the main character. Timmy can go flying quite far and is great for disarming harpoon traps.
* ChunkySalsaRule: A variation of the rule: [[OffWithHisHead You only lose control of your character if he or she is decapitated]] [[HalfTheManHeUsedToBe or (after a few seconds) if he or she gets ripped in half.]] Until then, crossing the finish line by any means will count as a success, even if you lose other parts of your body or your vehicle and shimmy down to the finish VideoGame/{{QWOP}}-style. In the case of couple characters, this only applies to the man in front.
* CoolButInefficient: Wheelchair Guy is the only character with a rocket attached to his vehicle, but it's way less impressive than it sounds. Unfortunately, all forms of thrust on his wheelchair (including the rocket) is below his center of gravity, so you'll most likely be too busy wobbling and keeping balance whenever you attempt to move in order to effectively avoid obstacles and navigate rough terrain. Therefore, he's suited for advanced players. But if mastered, [[GameBreaker you can fly through entire levels at your leisure]].
* CoolHelmet: The dad's helmet has been shown in some levels to protect against items such as ''meteorites''.
* CriticalExistenceFailure: As long as your head's still attached to your body or you're not split in half and part of your body's still steering the vehicle, you can keep going!
** However, the more mass you lose (whether through loss of limbs or passengers), the more unstable you are! If Irresponsible Dad loses both his arms, he's still able to pedal, but he's not gonna make any big jumps or loops anytime soon.
* CrowningMomentOfIndifference: Whenever the son of the Irresponsible Dad is killed, his only reaction is a flat and only slightly irritated 'dammit'. He sounds like he just lost a 5-dollar bet instead of seeing his son get horribly butchered!
** The man of the Moped Couple doesn't even react when his wife/girlfriend gets killed. The wife, however, says "WHYYYYY!?" in a [[LargeHam Large Ham]] manner if the man is killed.
** There's also the case of Santa and the elves. The elves don't react when one of them dies, but when an elf is killed, Santa lets out a jolly "Ho ho ho!"
* TheDeterminator: All of the characters will keep going even after losing several body parts.
* DifficultButAwesome: [[LetsPlay/UberHaxorNova The pogo stick guy]]. His controls are very hard to deal with, and getting him to go where you want him to is a bit of a chore sometimes. However, he is one of only two characters that can actually jump with no outside influence, and he is surprisingly durable while on the pogo stick, especially considering how everyone else is MadeOfPlasticine.
** But then again, he is the only one wearing a full set of [[FridgeBrilliance protective gear.]]
** With sufficient practice, it is possible for Wheelchair Guy to fly. Until Santa and Helicopter Man were added, he was the only character able to do so, and Wheelchair Guy's smaller and therefore more maneuverable than the other two.
* EpicFail: It's possible to die right at the start of the level. Even if there's no trap there, if you tip you can fall and break your head off.
** [[BonusPoints In extension of that]], you can break your legs by falling two feet.
** Or, if you try really hard to press the gas pedal before starting the engine on a car, you can [[HalfTheManHeUsedToBe RIP YOURSELF IN HALF]] instead.
* {{Expy}}: The Moped Couple of Amélie and Nino and [[BumblingDad Irresponsible Dad,]] Lawnmower man of Efficient Shopper, Explorer Guy of Indiana Jones, and Santa of [[ExactlyWhatItSaysOnTheTin Santa.]]
** Some have speculated that Lawnmower Man is an expy of Uncle Ruckus,but Jim has denied this.
* GameBreakingBug: Given that the maps are all user-generated, you will inevitably run into a map where something just does not work as it is supposed to.
* HalfTheManHeUsedToBe: Another way to die. Keep in mind after being split, you still have a few seconds of consciousness left before perishing. If you're lucky, you can reach the goal before then and [[InstantWinCondition still have it count]].
* HighPressureBlood: Any injury will spew forth a small fountain of blood, which will spray out around [[OverdrawnAtTheBloodbank a dozen gallons of blood]] before stopping.
* HiveMind: While playing as any of the characters that include two people, you control both, but you only notice it when the passenger is off the vehicle.
* HoistByHisOwnPetard: It's possible for the Lawnmower Man to get killed by his own mower, the Effective Shopper by her groceries, and the Helicopter Man by his propeller.
* InfantImmortality: Averted.
** "Dammit!"
* InstantWinCondition: One rule always applies here: ''If your main character touches the goal while alive, you win.'' Absolutely no other circumstances prevent this.
* LetsPlay: There are several [=LPs=] of the game on Website/YouTube, notably done by LetsPlay/UberHaxorNova, LetsPlay/PewDiePie, LetsPlay/YogscastSips, daneboe, and Creator/{{Tobuscus}}.
** OMFGCata adds his own "Best Of" from a livestream [[http://www.youtube.com/watch?v=0-DbYcJYRl8 here]].
* LosingYourHead: Inverted, as this is the most common way to lose. As long as your head is attached to your torso, you can control your character and pass the finish line (provided you haven't been split in half and died from that). Note that this applies only to the driver; the vehicle (and passengers for the Irresponsible Dad and Moped Couple) need not be present to win.
* LuckBasedMission: 99% impossible levels. There is no strategy to getting pass the harpoons other than being really lucky.
* LudicrousGibs: Another way to die. If your torso explodes, you're done. And with remarkable attention to detail, including multiple organs, a coil of intestines (Which can hold the two halves of a body together), and multiple slimy chunks of each body part. If a character's body is destroyed completely, the camera follows the heart.
* MadeOfPlasticine: You'll notice when playing the game that the characters are ''way'' more fragile than what a normal human body should take. You may even find your limbs breaking from something as trivial as ''accelerating'' if you're really unlucky.
* MajorInjuryUnderreaction: Every character will exclaim from limbs being torn off, but only for a second, and it is a minor reaction like "Oh, my leg!" Only when you start getting characters torn in half is when you'll start hearing the bloodcurdling screams.
* OwMyBodyPart: Wheelchair Guy will exclaim about his leg, should it get injured. Same goes with Pogostick Man's arm and foot.
* {{Plagiarism}}: while the game itself doesn't plagiarize anything, it happens [[InUniverse in-universe ]] with some of the levels being outright copies of other levels. Most common in rope swings, jet falls, and the infamous stair levels.
** 99% Impossible missions are all pretty much the same, "jump over a huge wall to a bunch of harpoons and get lucky."
** Bottle runs, pogo levels, and throwing levels are prime targets for plagiarism.
* PyrrhicVictory: Winning after being cut in half. You win the level, but you're going to die soon.
** [[BonusPoints Or,]] you win the level and then land on your head or slam into a wall, then you explode into a fountain of [[LudicrousGibs blood, bones, and guts]]
* RubeGoldbergMachine: Levels of the "Don't Move" or "Heart Donation" type are like this.
* RunningGag: The owl in The Astro Avenger, Renaissance Ravager, and Prehistoric Pilgrim. Lampshaded severl times.
* SickeningCrunch: Oh yes, the characters' limbs do squish and snap as they are torn off.
* SpikesOfDoom: A common hazard in many levels.
* SturgeonsLaw: In the early days of the game people would actually make real levels where the objective was to reach the end. Nowadays you will find the game populated mostly by guns, skeeball-type games, and "Kill Music/JustinBieber", with the platforming-type levels few and far between. Moderators have, however, recently begun making a token effort to try to avert this.
** Most [[ThrowingYourSwordAlwaysWorks "Knife/Weapon Throw"]] levels are practically identical.
** Level designers [[CompletelyMissingThePoint telling you to Rate their level 5 if you win]] is the rule, not the exception.
** Glass breaking levels, jet falls, and spike falls.
* ThisLooksLikeAJobForAquaman: The Space Bar Ability of the Explorer Guy, the ability to attach to rails, can only be used if rails are made available and under no other circumstances. In all other instances he's slow, clumsy, top-heavy, and thoroughly useless.
** Explorer Guy, at the very least, is relatively fast and on wheels. Pogostick Man, on the other hand, has to hop everywhere, and moves about as fast as one might expect, rendering many levels completely impossible for him to overcome. His jumping skills, however, are rivaled only by Wheelchair Guy's rocket, allowing him to scale large heights and skip entire portions of certain levels.
* TooDumbToLive: In Renaissance Ravager, the guy who [[OffWithHisHead sticks his head in the guillotine]] that clearly says "DO NOT TOUCH GUILLOTINE".
* VideoGameCrueltyPotential: The Irresponsible Dad. There is even a popular kind of level where the dad is required to slam dunk the child like a basketball.
** Some levels feature harpoons which target the character and may kill them. Fortunately, they will target the child if you throw him in the way of them.
** This is taken [[UpToEleven absurd levels]] in some user-created levels. Examples include the [[ExactlyWhatItSaysOnTheTin "Harpoon Run"]], where your character ''will'' look like a Pin Cushion, assuming they even [[EverythingTryingToKillYou make it to the end]], and [[{{SweetBroAndHellaJeff}} It Keeps Happening]], which is basically just a long stretch of stairs with a booster at the end; even if you try to bypass the stairs and go flying, your character will eventually land...[[BloodyHilarious and explode into a mess of bodyparts and gore]]. And of course, the Lawnmower Man. Anything he runs over will be cut up. That includes people.
* ShoutOut: Some of the more popular levels are based on [[SuperMarioBros Mario]], [[Franchise/TheLegendOfZelda Zelda]], And {{Limbo}}
* YourHeadAsplode: The last way to die. A decent hit to the head will cause it to explode gloriously.
