Your basic {{Mook|s}}, now for aquatic environments. Either they will be equipped with scuba gear (masks and air tanks), become more fish-like, etc. You'll definitely encounter them DownTheDrain or even in BubblegloopSwamp. This most commonly occurs with the MascotMook.

If it is an [[UnderTheSea underwater level]], then the hero is also given swimming skills so they can face these mooks as if they were on land; the difficulty in this case is that the [[GoombaStomp jumping on head]] option is usually taken away, making it impossible to avoid CollisionDamage (and forcing you to just avoid these guys) unless some other weapon is given. The other option (when on land) is that these guys jump in and out of water where they are unapproachable because of the hero's SuperDrowningSkills, so you have to hit them while they are out of it (if they can be damaged, that is). Some games (like ''Franchise/SuperMarioBros'') may have the same enemy show up in both roles, others will have different ones for the two environments.

Compare GasMaskMooks, similarly suited for unfriendly environments.

[[folder: Role Playing Game ]]

* There is this kind of Genesis Clone in ''VideoGame/CrisisCore'', namely the ones which Zack beats with a [[ParasolOfPain parasol]].
* In the ''Franchise/FinalFantasy'' series, there is ''VideoGame/FinalFantasyI'', ''VideoGame/FinalFantasyIII'', ''VideoGame/FinalFantasyV'', ''VideoGame/FinalFantasyVI'', ''VideoGame/FinalFantasyVII'', and ''VideoGame/FinalFantasyX'' which have underwater dungeons, and thus, enemies appropriate to the area (sea urchins, pirahnas, octopuses, etc.)
* In the underwater area of ''VideoGame/MOTHER3'', the standard Pigmask army is supplemented by Navy [=SQUEALs=].


[[folder: Shoot'em Up ]]

* ''VideoGame/{{Raiden}}'' and ''VideoGame/RaidenFighters'' series: Even though the player is relatively safe from "[[ImprobableAimingSkills Sniper]] [[DemonicSpiders Tanks]]" over the ocean, they have to contend with their "Sniper Gunboat" aquatic counterparts.
* The first boss in ''VideoGame/TimeCrisis 2'' is accompanied by aquatic ninjas.


[[folder: Tower Defense ]]

* ''VideoGame/MiniRobotWars'' has the land-based [[InvisibleMonsters stealth unit]] called the Mole. In the NewGamePlus, it gets the ability to swim on the water surface!
--> "Ocean doesn't save you from Mole anymore; for it can swim now!"
** And then you get even worse news later- the [[BossInMookClothing Giant]] also gets the ability to travel Amphibiously.
* Snorkel Zombies, Ducky Tube Zombies, and Dolphin Rider Zombies in ''VideoGame/PlantsVsZombies''.

* ''VideoGame/PlantsVsZombiesHeroes'' has [[PlayerMooks teammates]] with the "Amphibious" trait. This allows them to be played on water lanes, which are inaccessible to teammates without the trait. Plant classes specializing in Amphibious teammates are Guardian and Smarty, and Zombie classes specializing in them are Beastly and Sneaky.


[[folder: Wide Open Sandbox ]]

* ''VideoGame/{{Minecraft}}'' has Drowned, aquatic versions of normal zombies. These are spawned in water areas or transformed from a zombie that's submerged in water for a bit of time, and they are capable of swimming and staying underwater indefinitely. Furthermore, they can spawn with a Trident, which gives them a painful ranged attack.

[[folder: Literature ]]

* One ''{{Literature/Animorphs}}'' story starts when the Yeerks bioengineer gills onto their Hork-Bajir troops. It fails horribly, and the poor guys end up choking on air.
