Captain Jack: All hands to the boats! [sees Barbossa glaring at him, steps back] Apologies. You give the orders.A character is too dense to have any buoyancy, so they deal with bodies of water by walking across the bottom rather than swimming. This is a common strategy with characters who can breathe underwater, or creatures like zombies, golems, or robots who don't need to breathe at all. Of course, immunity to drowning isn't strictly necessary to walk underwater, but it helps. Often happens in video games, where this saves the programmers from having to code for swimming behavior, while averting Super Drowning Skills. Just make the character move slower and jump higher, give them an Oxygen Meter, and voila! underwater physics. If this is done by Fish People who should be capable of swimming, for no reason other than ignorance of the third dimension, see Water Is Air. See Walk on Water for an even more impressive version.

Anime & Manga
- Referenced in Ghost in the Shell with regard to the Major's hobby of SCUBA diving. Batou comments that he's never heard of a diving cyborg before, and for good reason: a buoyancy compensator failure would result in guaranteed death. Cybernetic bodies are far too heavy to permit unassisted swimming at all, and a cyborg stuck on the bottom thus would run out of oxygen long before he/she would be able to walk back to shore.
- Ikaros did this in Heaven's Lost Property, as she doesn't need to breathe and her body is too dense to float.
- Naruto - a division of Kabuto and Tobi's army of zombies and Zetsu clones reached a beach by walking along the seabed (at least in the anime).
- Zelgadis in Slayers is partially golem, which makes him too heavy to swim. That gives him one option if he falls into water.
- Some of the Fog ships in Arpeggio of Blue Steel walk on the bottom of the ocean on occasion.
- Zuikaku claims she sometimes swim, sometimes walk on the sea floor to get between her ship and the shore.
- When Ashigara goes to look for a sunken ship, she takes a stroll in the depths.
- In X-Men, this is Juggernaut's default way of crossing water. One of the most famous examples of this was after his first battle with Spider-Man in which he was buried in concrete so he simply tunneled his way into the Hudson River and walked out to sea.
- In the Astro City "Tarnished Angel" story arc, the Reformed, but Rejected Chrome Champion Steeljack escapes from a prison helicopter and falls into the river. He manages to hyperventilate himself and walks across the riverbed to shore.
- In Concrete, Ron Lithgow, the title character has noted that if he fell into a deep and large body of water, he would sink to the bottom without a big floatation device and/or special swimming equipment and his only chance of survival would be to walk on the bottom to a shallow area within an hour before he drowns.
- In The Return of Superman, a powerless Superman traveled from the Antarctic by riding inside a giant kryptonian battle-robot, who walked along the sea bottom.
Film – Live Action
- Pirates of the Caribbean:
- The Curse of the Black Pearl:
- The undead pirates walk along the ocean floor to reach Commodore Norrington's ships undetected.
- Earlier in the film, Jack and Will commandeer a skiff, turn it upside down and trap air inside it, and walk along the bottom of the harbor.
- In Dead Man's Chest, the crew of the Flying Dutchman walk from their submerged ship to the shore of Isla Cruces.
- The Curse of the Black Pearl:
- In The Crimson Pirate, Captain Vallo, his sidekick Ojo and The Professor use the upside-down trick to walk to shore after being chained to a dingy without rows or sails.
- Early in Highlander, Connor is thrown into a lake by Ramirez. He (Connor) can't swim, but can't die, either, so this happens-though the series proceeded to change the rules and make this impossible later on.
- The zombies from Land of the Dead are shown approaching Fiddler's Green by walking through a lake.
- Data does this in Star Trek: Insurrection, although it later turns out that he also has an optional floatation device - an apparent upgrade since the TV series.
- Apparently, a deleted scene from Friday the 13th Part VIII: Jason Takes Manhattan would've shown Jason doing this.
- All the Jaegers in Pacific Rim, on account of being way too heavy to swim even with humanoid design. In the final battle, they walk on the ocean floor to get to the Breach.
- Golems in the Discworld, being automata, can do this. When Boxed Crook Moist von Lipwig is assigned one as his parole officer in Going Postal, he is reminded that even fleeing to a different continent would not help him, as it would be able to walk any body of water eventually. In addition, said parole officer previously spent several decades at the bottom of a well manning a pump, and another golem spent several thousand years at the bottom of the ocean before it was recovered, but neither of them did much walking in that time.
- Zombies do the same, as Windle Poons just walks ashore after attempting to drown himself, and Reg Shoe contemplates walking all the way back to Ankh-Morpork along the bottom of the sea if their ship is sunk.
- Larry Niven and Steven Barnes' novel Dream Park. When the party escapes pursuing zombies by taking a small boat, the zombies walk into the water after them. The players forget that zombies don't need to breathe, and the zombies walk along the bottom and eventually grab one of the party members and drag her underwater.
- Mentioned in both The Zombie Survival Guide and World War Z as a reason to be careful around water during a zombie outbreak. It's also a reason to be vigilant after an outbreak, because you never know when a zombie might stumble out of the ocean and spark a new infection. However, he also stated the best place to be is on a boat. Doesn't matter if the zombies may be covering the oceans floor, as long as the water is deep enough, they cannot reach you.
- In Caves of Ice, a force of Necrons manage to wade through several levels worth of caves (of ice, naturally) that have been flooded with pure promethium (basically super-gasoline). This does not help them in the slightest when it explodes.
- Dortmunder and Kelp plan to do this in an attempt to retrieve a cache of stolen cash from under a lake in Drowned Hopes by Donald Westlake. It fails as they discover the inherent buoyancy of the human body.
- Midnight Tides, book five of the Malazan Book of the Fallen, has two examples:
- Ublala Pung is sentenced to death by a procedure called the Drownings, and made to swim across the canal burdened with a bag of gold. However, thanks to being a Tarthenal, he's bigger than a human and has four lungs, enabling him to simply walk across the canal's bottom and win his freedom.
- The Guardian, an entity of unspecified origin which is set up by Mael, Elder God of the Sea, to guard the names of long forgotten gods, is basically a suit of armor that walks around on the sea bottom and challenges any intruders.
- In one Gilligan's Island episode, an experimental robot lands on the island. He can't swim due to his weight, but the castaways discover that he's completely watertight, so they program him to walk to civilization and carry their message of rescue. The robot manages to complete the long trek, but fails to deliver the message because the lucky rabbit's foot Gilligan placed inside the robot played havoc with the magnetic tape on which the castaways had recorded their message.
- One Terminator: The Sarah Connor Chronicles episode revealed that terminators are too dense to swim. It's not as much of a Weaksauce Weakness as it seems, because it's only useful if the terminator doesn't have a gun and you are near deep water, and even then you only gain the time it takes for the terminator to sink to the bottom and walk out.
- In one episode of Star Trek: The Next Generation, La Forge tries to get through to a brainwashed Data by reminiscing about a time when the engineering crew went swimming in a planet's ocean, and Data tried to dive in and join them, whereupon his metal body immediately sank to the bottom and he had to walk several miles back to land. (Evidently this experience encouraged him to do some upgrading; in Star Trek: Insurrection he's able to serve as a "flotation device".)
- The Mythbusters tested the Pirates of the Caribbean example above and found it wouldn't work— the boat with its pocket of air is just too buoyant.
- Clumsy Carp can do this at will (and apparently hold his breath indefinitely) in B.C..
- Many videos and advertisements for BIONICLE's Mahri Nui storyline showed the characters walking around on the ocean floor, however, the books, comics and serials showed them swimming.
- Paranoia adventure Vapors Don't Shoot Back. When the PCs fight Black-U-BRD-5 aboard his pirate ship in the reservoir, it's possible for his robots to be knocked overboard. If they're still operational they can walk along the bottom and climb up a shaft back onto the deck.
- Basic Dungeons & Dragons adventure CM2 Death's Ride. During the siege of Gollim, a force of undead walk across the bottom of the nearby river and make a surprise attack on the town.
- Also a tactic of constructs, especially inevitables, who don't tire, don't breathe, and suffer few ill effects from water. (Maybe not iron golems, though.)
- Warforged from the Eberron setting are explicitly stated to be able to do this. However, since they are made of about 30% darkwood, they can still swim if they try.
- An undead serial killer, Aldern Foxglove, does this in an early Pathfinder adventure.
- As Humongous Mecha, BattleMechs in BattleTech will usually do this upon entering water deep enough for them to even worry about. This still leaves them as one of only two unit types that can move underwater by default at all (the other being, quite naturally, submarines). A rare few of them actually avert the trope by virtue of mounting "underwater movement units", basically ducted fans that actually do allow them to "swim" while fully submerged, but since those systems turn into dead weight on land where most combat happens they remain exotic specialists.
- Among the many feats of Badassitude of Street Fighter's Akuma is the ability to walk unfazed along the bottom of the ocean. Which he then jumps off of and splits the sunken ship he was standing on in two with his feet.
- Sonic the Hedgehog
- Sonic the Hedgehog can't swim at all—developer Yuji Naka initially gave him this limitation under the mistaken belief that real-life hedgehogs couldn't swim. So, depending on the game, Sonic either runs underwater or has Super Drowning Skills. He can however, move over the top of the water if he is running fast enough.
- The other characters walk along the bottom too but many of them have abilities that let them swim temporarily.
- In 2D Sonic games since Sonic 3, Tails can swim (as a rough analogue to his ability to fly above water). However he tires fast and then sinks.
- Knuckles can "glide" underwater in Sonic 3 and Knuckles in the Sonic Advance games this becomes a swim analogue like Tails' flying. The Sonic Advance series also gives Knuckles the ability to swim along the top of the water. In Sonic Adventure 2 he can swim freely and even gets a power-up that let's him breath underwater.
- In Sonic Colors, Sonic finally learns to swim... sort of. He still sinks like a rock and runs underwater, but he's capable of Double Jumping infinitely while underwater, which is basically swimming in all but name.
- He loses it in Sonic Generations despite it taking place not long after Colours. The Wisps might be involved in that infinite double jump - except for the white wisps they DO allow him to breathe underwater (and Frenzy moves much quicker when underwater compared to on dry land, to boot!)
- Extends to Mario & Sonic at the Olympic Games in the swimming events: Other Sonic characters can swim but Sonic has to wear a life jacket and looks like he's trying to run through the water.
- Mega Man, because he's a robot, natch. He did learn to swim for Mega Man 8.
- Mega Man ZX has the main characters, when in their 'base' forms (without Biometal) float up to the surface of the water. Certain specific Megamerges and forms can swim, but otherwise, this trope is played straight.
- Soma Cruz from Castlevania: Chronicles of Sorrow does the same thing until he gets the ability to play this trope partially straight - like the Sonic Colors example above, he and some other Castlevania protagonists can double-jump infinitely in water.
- Played straight in Terraria. Though there are items in the game that allow you to swim.
- The protagonist of Cave Story and Curly Brace are unable to swim underwater, or even jump higher than one block, except when swept along by a current, in which they can move in any direction.
- Subject Delta in BioShock 2 is permanently fused to his armored Big Daddy diving suit and therefore can walk on the sea floor indefinitely, but is far too heavy to swim. See also: every other Big Daddy, on all counts.
- Mario in Super Mario 64 when he has the metal suit power up.
- Super Mario Bros.: The Lost Levels featured Koopas that can walk underwater.
- Link in The Legend of Zelda: Ocarina of Time, The Legend of Zelda: The Wind Waker and The Legend of Zelda: Twilight Princess, when wearing the Iron Boots. This is also an ability of Zora Link in The Legend of Zelda: Majora's Mask. Zora Link is perfectly capable of traditional swimming; walking underwater is purely optional.
- Samus in every Metroid game since Super Metroid. The Gravity Suit, which is supposed to allow free movement in water, combines Walk, Don't Swim with Water Is Air. Presumably the suit is still too heavy to permit actual swimming, or it would be improbably difficult to swim straight with one arm significantly larger and heavier than the other. Regardless, Samus's suit means she doesn't have to worry about oxygen, so being underwater is just annoying until you get the upgrade.
- Metroid Prime 2 gives the player a propeller along with the Gravity Suit, allowing the player to hover a limited distance underwater.
- In The Secret of Monkey Island, Guybrush is tossed in the sea tied to an idol, and is able to walk around at the bottom. He can also do this in the sequel when investigating a sunken ship, in The Curse of Monkey Island (as an Easter Egg), in Escape from Monkey Island while searching for a treasure hoard under a lake, and in Tales of Monkey Island.
- Snake, in the first Metal Gear Solid and in its remake, The Twin Snakes.
- In the second game, there is a swimming section where you have to manually open a couple doors. If you stop before opening the door you can walk around on the floor, albeit very slowly.
- Master Chief, when jumping into the coolant pools during the "Keyes" sequence in Halo: Combat Evolved. Or if you drive into the ocean on the beach level (no reason to, but hey, you can do it). Justified, as the MJOLNIR armor is stated to weigh well over a ton. The same mechanic is shown in cutscene in Halo 2, in which MC jumps into Delta Halo's "ocean" to avoid a Covenant plasma attack and goes straight to the bottom.
- Ironically averted with his ragdoll in Halo 3. Nothing like watching more than a ton of solid steel armor float down the river. Played straight in the actual gameplay (when Master Chief is alive). Jumping into deep water make you sink and kills you instantly (likely for gameplay reasons; Master Chief should be able to survive it, but since there's no actual way to get yourself out of the deep body of water, you just die). There are some places where the water is deep enough to immerse yourself, but not deep enough to kill you. It can make for handy cover.
- Creatures who wind up in water in the latter two games in the main trilogy will typically wander around on the bottom until they drown, although there are third-party objects available that will allow certain creatures to swim.
- The player character in An Untitled Story can't swim, but sure is buoyant underwater. Said player character is a flightless bird-like creature (that, sadly, is not a penguin).
- In NetHack you can walk across the bottom of water if you're wearing an amulet of magical breathing. However, each turn spent underwater has a chance of rusting your iron equipment, diluting your potions, and erasing your scrolls via washing out their ink (unless you store all that stuff in an oilskin bag); plus, the water current pushes you around. Since there's multiple other ways of crossing water, this is usually reserved as a last resort.
- In Space Station Silicon Valley, some of the animals you take control of do this.
- You can alternate between this and normal swimming in Alundra 2.
- Things with a [NOBREATHE] tag in Dwarf Fortress walk around on the bottom of water-filled areas with a speed penalty instead of swimming. In Adventure Mode, you can choose to wade through water below a certain depth, but have to swim if a z-level is filled with water to the top.
- In Battle for Wesnoth, skeletons are the only non-flying, non-swimming unit to be able to enter Deep Water terrain, though only slowly and with very poor dodge rates. They also have the "submerge" special ability, which makes them difficult to see when they are in deep water.
- In XCOM: Terror from the Deep, every unit in an underwater mission walks on the sea bed, except for Tentaculats and Hallucinoids.
- In Trine, the Knight is the only protagonist who walks underwater instead of swimming. Not too surprising, what with being clad in full suit of plate armor.
- Warrior Kings has two super units, the Archangel and Abbaddon, doing this.
- World of Warcraft: Cataclysm has this option in the new Vashj'ir zone as part of a swim speed/underwater breathing buff, along with similar mechanics added into the old zones.
- Done by Sora in Kingdom Hearts 3D in the aquatic segment of the Prankster's Paradise world. He's shown swimming perfectly fine in the cutscenes there.
- An entire army pulled this off in one of the 2920: The Last Year of the First Era. A group of mages helped them breathe underwater and bypass Dunmer defenses to sack a city.
- The commanders from Planetary Annihilation do this, while all your buildings are constructed on little rafts while on water.
- Minecraft players may choose to do this when crossing shallow water, only coming up to breathe when their air runs out, as a way to save the hunger cost of swimming. Works even better with a Respiration-enchanted helmet. Inverted at the same time with non-aquatic mobs who constantly swim up when in water, even enemies like zombies and creepers that would benefit from sinking to reach a diving player.
- Civilization: In the Test of Time fantasy map, most units that can travel to the undersea map appear to do this.
- Shovel Knight's eponymous protagonist can't swim and instead has to rely on greatly improved jump height when underwater.
- Fallout4: any character wearing Power Armor will walk underwater instead of swimming. (The armor has a breathing system, even when the character is not wearing the helmet.)
- Jones from Gunnerkrigg Court walked from a boat to the shore, rather than trusting her weight to a rickety pier.
- The opening of Last Blood has a zombified nazi who was buried at sea walking out onto a beach to begin the outbreak.
- Questionable Content: Momo's android body has a waterproof skin, but is not buoyant.
- The whole village of zombies in Looking for Group traveled across the sea to Kethenecia this way.
- In the episode "Serpent's Pass" of Avatar: The Last Airbender, the Gaang go underwater in a giant air pocket to cross a gap in the Serpent's Pass. It would have worked, too, if not for the giant serpent.
- In one episode of The Simpsons, Homer gets pulled out to sea by a rip tide and can't swim back. He tries to sink to the bottom and walk back, but gets exhausted after a few steps.
- In Superman: The Animated Series, Metallo is seen doing this after apparently sinking to his doom.
- One episode of Transformers Prime set in the Antarctic involved Starscream getting a set of Power Armor that made him nearly invulnerable. However, due to the loss of his T-Cog, he was unable to fly, so Optimus and Dreadwing simply blew the ice out from under him to send him underwater. But since Starscream doesn't need to breathe, he's seen wading along the seafloor at the end of the episode.
- Napoleon Dynamite and his friends inexplicably do this in one cartoon.
- The Looney Tunes short Wagon Heels has Injun Joe crossing a river this way. For comedic effect, he suddenly emerges on the other side the second his head submerges.
- This is what tanks do to tread water barriers. One of the reasons Germany had an edge over Soviet Union during the beginning of WW2 was that the Soviets wanted their light tanks to swim, rendering them too lightly armored to be of any use, while Germans made their tanks able to go underwater with snorkels and thus able to cross most rivers while retaining their combat capabilities.
- This approach was rather less successful when they initially attempted to use it to cross The English Channel.
- This is how hippos move. They are actually very unadapted to actual swimming, so they walk on the river bottom.
- Astronaut training typically includes practicing various tasks in space suits in water tanks. Candidates for possible future Moon or Mars landings will be required to do this in suits calibrated to simulate their weight at their target destination, so they'll do most of their work walking/bouncing on the tanks' bottom rather than free-floating above it.
- The flamboyant cuttlefish is less buoyant than most cuttlefish species, due to its reduced cuttlebone. It normally moves by floating just above the muddy seabed and dragging itself forward with its bottom pair of arms.
- This is how diving suits work: A person inside the suit presurized to stop the water from crushing them can freely walk underwater for as long as they have oxygen and their suit doesn't decompress. Of course, if that happens, it's not a pretty sight.
- The final exam of the German Kampfschwimmer (Combat Divers; allegedly more Badass than their US counterparts, the SEALS, but slightly less impressive than the UK Special Boat Service) involves an apnoe walk around the bottom of a training pool, which is why until today, no woman has ever passed the test (lack of lung volume).
