A common Weaksauce Weakness is flipping something or someone on their back. While it is possible to reorient, it usually takes a significant amount of wobbling to do so, leaving one vulnerable.
In video games, this is very effective against Stone Wall enemies, especially shelled ones.
- In a mid-1990s commercial for Snapple, a young man writes in to the Snapple Lady asking if Snapple has a mascot (and if not, could he be it)? Snapple sends him to mascot boot camp, and he discovers the hard way that once you fall over while wearing a fake giant glass jar over 70% of your body, its pretty near impossible to get back up again.
- Naruto: As a part of their preparations for the Fourth Shinobi World War, the Allied Shinobi Forces send Naruto and Killer Bee to hiding on an island in the Land of Lightning. In reality, this island is a gigantic turtle. When Kabuto attacks the island, he uses the fact that it's a living creature to his advantage by flipping the turtle upside down with the combined effort of Manda II (a genetically altered giant snake summon) and Deidara (who Kabuto brought Back from the Dead with his Impure World Reincarnation technique).
- Ash's Squirtle from Pokémon has frequently wound up helpless after landing on its back—until Ash taught it how to use Hydro Pump to both free himself and counterattack from that position.
- In Amada Anime Series: Super Mario Bros, Mario helps a Boomerang Brother who was stuck on his shell. In his gratitude, the Boomerang Brother travels with Mario to defeat Bowser.
- This happens to Tamatoa while he's pursuing Moana and Maui. Also a case of Hoist by His Own Petard in that his shell is so heavy due to all the gold he's attached to it because of his vanity.
- Earlier in the film, a young Moana ignores a beautiful conch shell to save a baby turtle that has been stranded on its back. It is implied that this kindness is what made the Ocean choose her to restore the Heart of Te Fiti.
- In Giant Monster Gamera, the army attempted to invoke this to stop him. In their defense, no one could have anticipated the giant turtle would fire rocket boosters out of its shell and fly away.
- Gamera vs. Viras (AKA Destroy All Planets): the giant turtle Gamera is trapped lying on his back (shell) and a giant alien with a pointed head repeatedly spears him in the stomach while he's helpless.
- In A Christmas Story, Ralphie's little brother is dressed up in so many layers for the Indiana winter, he can't get back up when he falls down. The narrator even mentions he looks like a turtle on his back.
"Randy lay there like a slug. It was his only defense."
- Blade Runner: In the Voight-Kampff test that Holden gives to Leon, one of the questions involves a flipped tortoise.
Holden: You're in a desert walking along in the sand when all of a sudden you look down and you see a tortoise. It's crawling towards you. You reach down and you flip the tortoise over on its back. The tortoise lays on its back, its belly baking in the hot sun beating its legs, trying to turn itself over, but it can't. Not without your help. But you're not helping. Why is that?
- RoboCop (1987): ED-209's Weaksauce Weakness to stairs also displays its total inability to right itself after tipping over. It's left helplessly flailing and squealing.
- In Jurassic World, the Indominus rex picks a fight with a group of Ankylosaurus. Most of them scatter, but one stands her ground and uses her armor and tail to fend off the invader. After failing to bite through her back, the Indominus flips her over to kill her.
- Om in Small Gods. Having been a powerful God once, and being that someone who proclaimed to serve him faithfully had been the one to flip Om over, he took it hard.
- In Jules Verne's The Mysterious Island, the protagonists found a giant sea turtle in this condition. However, while they went to bring a cart and carry it home, the turtle was carried away by a high tide.
- In Way of the Tiger, your ninja hero Avenger can flip enemies on their backs with different throw techniques. Avenger then follows up with an attack that gets significant bonuses to hit and damage.
- In an episode of M*A*S*H, an ambulance-truck flipped on its back demonstrates to Colonel Potter the general unfitness of his camp: after everyone pushing together can't get it rightside up, a group of six Marines happens by and rights it all by themselves.
- My Name Is Earl: Crabman's pet turtle Mr. Turtle is scared of being flipped on his back, at least according to Crabman.
- It also describes Randy, according to Earl.
- Elementary: Sherlock brings home the pet turtle which used to be owned by the Victim of the Week, claiming he is going to make turtle soup out of it (after fattening it up first). At one point he uses it as a paperweight by putting it shellsidedown on a stack of papers. Joan is not pleased.
- This was a common weakness in the early seasons of Robot Wars, which made wedges a popular shape and hydraulic flippers their Weapon of Choice. However, eventually competitors started entering robots which were either able to work both ways up, rolled or (for maximum Rule of Cool) use a SRIMECHnote to flip themselves back over (after Cassius was able to do so with its flipper in the second season).
- The A-Team was very fond of flipping over the vehicles of the bad guys in rather spectacular fashion; no matter what the stimuli was, they would normally fly into the air, flip 180 degrees and land upside-down. It even had its own camera angle to show this happening.
- Super Mario Bros.:
- Mario Bros.: Mario and Luigi could flip turtles (Shellcreepers) over by jumping up from directly below and hitting the level the turtle was walking on. If neither Mario nor Luigi ran into the turtle and knocked it off, it would eventually jump out of its shell, kick the shell over, get back in and continue walking. This could be done with crabs (Sidesteppers) as well, but required two hits.
- Similarly, in Mario & Luigi: Superstar Saga, the brothers can't get past the giant Koopas (known as Ankoopas, as in anchor koopas) until they've learned the fire dash attack.
- In Mario & Luigi: Bowser's Inside Story, certain enemy attacks could knock Bowser on his back, costing him several turns.
- Whenever Mario or his friends defeat him in Super Mario 64 (DS) by throwing him into a bomb, Bowser lands on his shell and groans in exhaustion in the original version, and helplessly flaps his arms and legs in the DS version. Bowser realizes there's nothing else he can do and promptly escapes while leaving behind a special key or the Giant Star.
- Paper Mario series: Koopas can be flipped on their backs when Mario jumps on them, which also lowers their defense. Beware, though: This can happen to Koops in Paper Mario: The Thousand-Year Door. This is subverted by the "Shady Koopa" enemy in this game, as they gain a more dangerous attack when flipped on their backs.
- This is how you defeat Hookbill the Koopa in Yoshi's Island and (adult) Bowser's first form in Yoshi's Island DS; Flip them over, then Ground Pound their underside to cause damage.
- Similar to the Yoshi's Island example but more infamous: the Giant Enemy Crab from Genji: Days of the Blade.
- The Spiked Beetle, Terrorpin, and Snapper are various enemies in The Legend of Zelda series that are based on turtles and thus have this weakness. Typically they can be flipped with the hammer or the shield, or in the latter case, by getting underneath them using a Deku flower.
- The boss of the fourth dungeon in Oracle of Ages, beaten by flipping it with the Switch Hook.
- Walking Skullatulas in Skyward Sword, unlike their more difficult to hit hanging cousins, are easily flipped to expose their soft under belly for a Finishing Strike.
- Armogohma from Twilight Princess lands this way when you shoot her in the eye with an arrow. This gives you an opportunity to control the nearest statue to her and deal a damaging blow. Also, the giant insect in twilit Lanayru lands this way once you've gotten it twice, allowing you to jump on it and use the area attack on its legs, thus dealing the finishing blow.
- In Shadow of the Colossus, this is the weakness of two bosses. The eighth Colossus is only vulnerable when it falls and lands on its back, while the ninth is flipped.
- In Mega Man X8, the Mascot Mook Mettaurs are flipped over when hit by an Armor-Piercing Attack.
- The Hobby Horse and, in a New Game+, the Teapot Cannon, are good for inflicting this on Cannon Crabs in Alice: Madness Returns.
- In Xenoblade, this is a status effect called "Topple" which can only be activated after triggering another status called "Break".
- Dead Rising 3: The cutscene after defeating Darlene has this happen to her after her mobility scooter runs over some of her puke, before she's killed by choking on her own vomit. Justified due to her obesity.
- In Paladins, Makoa is a bipedal turtle whose "stunned" animation has him flailing about while stuck on the back of his turtle shell.
- Teddie from Persona 4 has a nearly spherical body, so struggles to get up when pushed on his back.
- Epic Battle Fantasy: In the fourth game, when Mighty Oak is defeated, and therefore, tipped over, Anna says:
And he's down! Don't worry, he's not hurt at all. He just can't get back up from that position.
- Super Smash Bros.: In Brawl and Ultimate, if Squirtle is footstooled while using its Side B special, it will become helpless on its back.
- Drowtales: This trope is lampshaded when Kiel'ndia Val Vloz'ress' turtle golem gets flipped upside down by the Beldrobbaen spellcasters:
"Once a turtle is on its back, it's done for."
- Questionable Content: Robot Buddy Winslow had been deliberating whether to upgrade to a humanoid body or stick with his current iPod-shaped one (a flat rectangle with stubby arms and legs). After spending about half a day stuck on his back, unable to get up until Hannelore came home and helped him, he decided that yeah, it's time to upgrade.
- Goblins: Subverted with Kore, whose 24-hour plate armor and oversized tower shield getup includes a mechanical apparatus that stands him back up when he's knocked over.
- The Simpsons: When Selma takes Bart & Lisa to Duff Gardens, Surly (one of the costumed mascots, dressed as a Duff Beer bottle) falls over and can't get back up again.
- On the Futurama episode "Crimes of the Hot", Bender rescues a turtle because he feels a kinship with it, because he too can't get up when laid on his back. (He claims that all those times he got up from his back he was actually slightly on his side.) At the climax, when all the robots have to vent their emissions upward to save themselves, Bender and the turtle are on their backs, unable to get up. Then the turtle manages to flip over, which gives Bender the incentive to do the same.
Bender: I'm even greater than I thought I was!
- Avatar: The Last Airbender: Aang tries to invoke this trope by flipping over the Fire Nation's Tundra Tanks with his airbending powers. However, this doesn't end up working like he hoped for: for the sole purpose of averting this trope, the design of the Tundra Tank includes a rotating cabin.
- Inverted by Weebles, whose theme song brags about how easily the pear-shaped characters avoid this fate: "Weebles wobble but they don't fall down."
- Played very straight for sheep, and some other ruminants, especially when pregnant or with a thick, heavy fleece. Shepherds call this deadly state being "cast", "kessing" or "kewped". A cast sheep needs only the slightest dip in the ground, sometimes none at all, to become fatally trapped. Their inability to "eructate" gases from the rumen in this position makes them "gas up", swelling to make it even harder to right them. Death, especially in summer, can be swift due to overheating, dehydration, exhaustion, and inability to flee predators such birds and badgers who will happily feast on exhausted sheep. Travelers in sheep-farming areas are encouraged to watch for this, and to right any cast sheep if found. Here's how to save a sheep's life.
- Ironically, not Truth in Television when it comes to most species of actual turtles and tortoises, which can use their heads or tails to right themselves if they wind up on their backs (though it may take some time and considerable effort).
- Occasionally played straight with pet turtles kept in shallow water. It's rare, but sometimes one will manage to have enough difficulty righting itself that it drowns before it can do so.
- Grounded horse shoe crabs.
- For obvious reasons, this trope applies to pretty much every single human-built ground vehicle ever. Whether it was a tank, a horse carriage or a motorcycle, if its wheels don't touch the ground, it ain't moving. To avoid this trope is why vehicles meant to travel on uneven terrain need to have a low center of mass.
- In addition, leaving a vehicle flipped on its back can have long-term consequences as well, since most internal combustion engines were not designed to be inverted; gravity will cause the oil and fuel in the engine to drain "upwards" into the engine and into areas oil isn't meant to go. The effects can range from causing a smoking mess when restarted to causing the engine to seize up completely or even catch fire.
- Inversion can also cause significant problems for many aircraft, ranging from their airfoils no longer producing upward lift for obvious reasons, to their engines and fuel systems not being designed with inverted flight in mind. For example, many smaller airplanes are designed so the fuel tanks sit higher than the engine, such as in the wings. This allows gravity to pull fuel from the tanks into the engine. Invert the plane, and gravity will no longer pull fuel to the engine.
- A porcupine's quills are on top, so it's quite vulnerable if flipped over. Fisher cats, which aren't cats at all but large weasels, are one of the few animals capable of rendering a porcupine Flipping Helpless.
- Shrews have learned this trick to prey on certain species of poisonous toads who only have poison on the skin of their heads and backs. Flip them over, and the shrew can tuck into its tasty and non-poisonous belly and innards.
- Like the above example, some carnivorous Australian birds are learning how to have a good meal of cane toad.
- Pillbugs probably suffer from this more than turtles. When flipped they'll struggle impotently trying to roll back over to their original position (though they can still usually right themselves).
- Used as a Cool and Unusual Punishment in the military, dubbed 'The Dying Cockroach'. Watch it in action.
- Sharks have a variant of this: if they remain upside-down for longer than a few minutes they enter a trance-like state dubbed "tonic immobility" and are unable to move. Orcas have learned to exploit this and will hold sharks upside-down until this happens, then eat the shark's liver without it fighting back.
