'''''Piranha 3D''''' is a remake (in name only, really) [[Film/{{Piranha}} of the original]] Creator/JoeDante B-movie, directed by Creator/AlexandreAja.

Set at Lake Victoria, a minor earthquake opens up a chasm that connects the lake to a larger subterranean one. The local sheriff (Elizabeth Shue) escorts a trio of scientists to explore the underwater cave, while her chief deputy (Ving Rhames) is left to oversee the chaos of Spring Break. However, thousands of prehistoric piranha that have outlived their species' extinction by millions of years are now able to escape to the surface, eating two of the scientists, and then making their way towards the town's very active beach.

Also filling out the adult cast are Jerry O'Connell (a Girls Gone Wild-esque producer/director), ChristopherLloyd (a marine biologist), and [[TheCameo Richard Dreyfuss]] ([[DeathByCameo a local fisherman who is the first to get eaten]]). As increulous as it may seem, the film actually got mostly ''positive'' reviews, for being realistically scary, but also knowing when to indulge in it's BMovie roots. One year later, a sequel was announced. At the 2011 Spike TV Scream Awards, the trailer for '''''Piranha 3DD''''' premiered. Lloyd, Rhames, and Paul Scheer (O'Connell's cameraman) reprise their roles while [[TheVampireDiaries Danielle Panabaker]] played the lead.
----
!!The 2010 3D film provides examples of:

* ActionMom: The sheriff. [[MamaBear She shows no hesitation to go help her kids when they're in danger.]]
* AttackOfTheKillerWhatever
* AttackOfTheTownFestival: Actually spring break, but close enough.
* BadAss: Ving Rhames as Deputy Fallon.
* BittersweetEnding
* BMovie
* BlackComedy: The deaths are sometimes over-the-top hilarious, but still remain horrifying. [[spoiler: The death of Novak at the end definitely fits this.]]
* BloodierAndGorier: Ramps this up to ridiculous levels, and it's obviously intentional.
* BloodyHilarious: Some of the deaths, such as the DiagonalCut scene and the girl who, while being carried to shore by two guys, turns out to be more injured than they thought, as the one holding her legs [[MadeOfPlasticine accidentally rips]] the bottom half of her torso off.
* CassandraTruth: The police warn the partygoers to get out of the water, but nobody listens until the blood starts spilling.
* CelebritySurvivor: Porn stars and a sleazy Joe Francis clone are among the {{red shirt}}s.
* ChekhovsGun: [[spoiler: The propane tanks]]
* ConspicuousCGI: Joe Dante's advice to Alexandra Aja, the director of the 2010 version, was "even if you're doing the fish in CGI, use puppets". It's very easy to tell which piranha is CG and which fish is a physical prop.
* CruelAndUnusualDeath: Lots and lots of this, including non-piranha caused deaths: a girl gets sliced in half by a high tension wire and watches her bikini top fall off before [[DiagonalCut the rest of her upper torso follows suit.]] Another girl's hair gets tangled in the propellers of a speedboat, ripping off her scalp and face. The host of a Wet T-shirt contest is decapitated. In more piranha-related news, a piranha eats a woman from the inside out, emerging from her mouth. Two piranhas fight over the severed [[spoiler:penis]] of a pornographer...and didn't like it in the end.
* DeadStarWalking: [[spoiler: [[TheCameo Richard Dreyfuss]]]].
* DeathBySex: promiscuous spring-breakers, a pornographer, and wet t-shirt contest host ([[DeathByCameo played by]] Creator/EliRoth) are on the receiving end of the piranhas' teeth.
* DiabolusExMachina: Although the ending wasn't really candy and rainbows, it was revealed that [[spoiler: the piranhas throughout the movie were actually babies, and an adult piranha eats one of the protagonists.]]
* DistractedByTheSexy
* DistressedDamsel: Kelly.
* FamousLastWords: Derrick saying to Jake "Wet t-shirt. Wet t-shirt." for no apparent reason.
* FanService: First half of the film is filled with lots, particularly the underwater nude ballet between Kelly Brooke and Riley Steele.
* FanDisservice: Then cue the piranha attacks. Many very beautiful people (in bathing suits) are killed in ways that combine sex and gory violence. For example, the girl who gets sliced in half by a high-tension wire as mentioned earlier: first the bikini top falls off, exposing her breasts... then the rest of her upper torso follows suit. Also Jerry O'Connell's severed penis, which is even more horrific if you saw it in theaters in 3D.
* FictionalCounterpart: The plot revolves around a Wild Wild Girls production/event, an obvious parody of Girls Gone Wild.
* FlyingSeaFoodSpecial
* {{Gorn}}
* GroinAttack: Jerry O'Connell gets his penis bitten off by the piranha.
* [[HalfTheManHeUsedToBe Half The Woman She Used To Be]]: Happens to quite a few bikini babes. Two notable examples:
** Two girls get sliced by a flying steel cable and...
** A few scenes later, one seemingly uninjured girl being hauled ashore by a couple of cops literally falls apart in their arms.
* HazardousWater
* HeroicSacrifice: See [[YMMV/{{Piranha}} Crowning Moment of Awesome]].
* HorrorDoesntSettleForSimpleTuesday: Spring Break.
* HookerWithAHeartOfGold: A porn actress rather than a hooker, but Kelly Brook's character is otherwise this to a tee. She quickly becomes a sort of surrogate CoolBigSis to the teenage hero, [[ShipperOnDeck tries to get him to kiss the girl he has a crush on]] and is the only character to show grief when [[spoiler: the {{Jerkass}} porn producer dies. Not that any of this stops her becoming fish food of course.]]
* HotterAndSexier: Than the previous versions, by far - lots of nudity, including the aforementioned nude ballet.
* ImprovisedWeapon: Ving Rhames' character runs out of ammo, so he takes the motor off of a boat and uses it to chop piranhas up like a blender.
* InfantImmortality: Curiously played straight, unlike the original.
* LargeHam: ChristopherLloyd, of course. Jerry O'Connell also gets really into his role, to hilarious effect.
* LudicrousGibs Not surprising, considering the fact that many characters are...
* MadeOfPlasticine: Some of the results of the attacks look like this, particularly the girl who's accidentally pulled in half while being carried to shore.
* MoodWhiplash: Goes from goofy 'teens on a porn set' scene, to standard horror movie stuff that could still pass for goofy/comedic, to a several-minute scene of unusually realistic gore.
** Especially the aftermath of the lake massacre where the survivors are being pulled out of the river.
** At one point in the aftermath, you see two girls on a boat holding each other and sobbing, while one of the boys on the boat passes a water bottle to another boat to help care for survivors. What used to be a bunch of douchebag rebellious teens getting massacred quickly turns into a bunch of terrified and traumatised kids trying to pick up the pieces of their foolishness. It's a very sobering switch.
* NiceJobBreakingItHero: Jake's decision to help out with filming the porn video leads to both Kelly and his younger siblings trapped on a boat surrounded by piranhas. [[spoiler: He makes up for it by rescuing Kelly and blowing up the boat along with hundreds of piranhas.]]
* NoCelebritiesWereHarmed: Averted. Jerry O'Connell said that his character was explicitly based on Girls Gone Wild founder Joe Francis, and insisted on giving him the goriest death in the movie.
* NudeNatureDance: The underwater ballet scene.
* OhCrap: [[spoiler: They're the ''babies''.]]
* PiranhaProblem
* RefugeInAudacity: Good lord.
* SmugSnake: Not really a villain, but audiences just love to hate Derrick Jones' manic douchiness.
* StealthPun: When Jerry O'Connell's [[spoiler:severed penis]] is sinking to the bottom of the lake, two piranhas start fighting over eating it. In other words, [[spoiler:a cockfight.]]
* TeensAreMonsters: One of the teens grabs a boat just for himself and tries to go for shore, running over several people in the process and killing a few of them.
* TooDumbToLive: Almost everybody. But especially the spring breakers, who refuse to get out of the water when the cops and the ''sheriff'' herself tells them that it's an emergency. Words like that usually scream shark or alligator/crocodile if you're in or near deep water.
* {{Third Is 3D}}: The marketing title ''Piranha 3D'' is somewhat confusing, making it look like the film might be a second sequel rather than another reworking.
** It is the second remake, making it technically the third ''Piranha'', just not a sequel to ''Film/PiranhaPartTwoTheSpawning''.
* TrailersAlwaysSpoil: An annoying example. That scene in the trailers where [[spoiler: a giant piranha leaps out of the water, and snatches a character off the boat?]] ''That's the ending.''
* UnderwaterKiss: It's an underwater ''[[{{Fanservice}} nude]] [[UpToEleven ballet]]'', as mentioned several times above.
* VomitIndiscretionShot: In slow-motion, right at the camera. And it's {{Squick}}-inducing enough in ''2D''...
* WhatHappenedToTheMouse: Cameraman Andrew vanishes without trace three quarters of the way through the movie. It can be safely assumed he was eaten by piranha but it's weird we never see his fate considering all the other victims on the same boat get very graphic and obvious deaths.
** WordofGod says he was to fall off the boat and swim towards shore only to have his nose bitten off by a piranha. The scene apparently ended up being cut due to being a special effects headache and all that remains in the finished film is a *very* brief shot of Andrew falling overboard when the boat hits the rocks.
** Seemingly the above was retconned as Andrew subsequently turns up alive and well (complete with intact nose) in ''Piranha 3DD''. His disappearance (and survival) in the first film remain unexplained.
** Not once did they explain (or even mention) what happened to [[spoiler: Sheriff Julie Forester, Jake, Kelly, Zane, or Laura]] in the sequel. Although given how this movie ended...

!!The sequel ''Piranha 3DD'' contains examples of:
[[quoteright:300:http://static.tvtropes.org/pmwiki/pub/images/piranha_3dd_poster_8843.jpg]]

* AdamWesting: Creator/DavidHasselhoff as a jaded, womanizing {{jerkass}} version of himself.
** ActorAllusion[=/=]SelfDeprecation: One of his lines involves him saying [[Series/{{Baywatch}} that he's never been a lifeguard]].
* AsHimself: Guess who.
* {{Badass}}: Ving Rhames. Again.
* BittersweetEnding: Sort of.
* BloodierAndGorier: Averted. While the film has quite a bit of blood and gore, it is nowhere near as violent as the first.
* CassandraTruth: Chet refuses to believe his step-daughter Maddy about the piranha, at least as far as them getting into the park. He does at least know they're real.
* CorruptCorporateExecutive: Chet.
* DeadStarWalking: Gary Busey.
* DeathBySex: Ashley and Travis.
** Averted with Shelby and Josh. Although Shelby apparently went insane, and Josh [[GroinAttack had to cut something off...]]
* DenserAndWackier: The sequel is much more comical compared to the first.
* DirtyCop: Kyle, who receives bribes from Chet to look the other way regarding the illegal activities and safety code violations at his park. He later shows himself to be a DirtyCoward as well.
* DoggedNiceGuy: Barry, to Maddy.
* DoubleEntendre: The very name of the film. ''3'''DD'''''?
* EyeScream: [[spoiler: Kyle]] gets impaled through his eye by Barry's trident used for picking up trash.
* FinalGirl: Maddy.
* {{Foreshadowing}}: "It's not like the fish are going to [[spoiler:follow them home]]."
* HotterAndSexier: The T&A is greatly ramped up compared to the original. In-universe, this also applies to the water park after Chet's renovations, with reduced admission costs for hot women, pole-dancing female lifeguards, and an "adult pool" which has an underwater video camera hooked up to a giant screen (for better viewing of the bottom-less ladies) and guests permitted to skinny-dip and even have sex in the water. Maddy is not amused by any of this.
-->'''Maddy:''' Please tell me you didn't just fire our old lifeguards and replace them with strippers!\\
'''Chet:''' ''Water-certified'' strippers.
* InfantImmortality: Played straight [[spoiler: until the very last moment before the credits]].
* {{Jerkass}}: Chet, Kyle and DavidHasselhoff.
* LateArrivalSpoiler: Deputy Fallon is still alive, and still as {{badass}} as ever. Not only is this a spoiler for the first film (where he supposedly died), [[TrailersAlwaysSpoil it's one of the main money shots in the trailer.]]
* MadeOfPlasticine: Like in the first film. Particularly notable is [[spoiler:Chet's]] death. He gets his head cut clean off by a flag string while driving a golf cart. It'd have be [[SharpenedToASingleAtom monomolecular wire]] to have that kind of cutting power at such speeds. [[spoiler:A land-walking piranha also bites a boy's head clean off, despite the size difference between it and the head in question.]]
* MistakenForGay: Barry, after his confession to Maddie.
* MustNotDieAVirgin: It's Shelby who doesn't want to die a virgin. If only she had better timing.
* TheReveal: The piranha [[spoiler: can now walk on land.]]
* TheSocialDarwinist: David Hasselhoff displays these tendencies in his refusal to help those in the water.
* TheStinger: [[spoiler:Creator/DavidHasselhoff as... ''[[MundaneMadeAwesome Fishhunter!]]'']]
* ThoseTwoGuys: Deputy Fallon and Andrew fall under this.
* ToiletHumor: Three minutes into the movie we see a dead horse farting out piranha eggs.
** There is also an in-universe example. Apparently, one of the most popular YouTube videos is of a "laughing diarrhea baby".
* TooDumbToLive: Lampshaded by the Hoff when he sees the people getting eaten by piranha. If they'd just get out of the pool, they wouldn't be facing this problem.
** Heck, throughout the film, he keeps seeing some dumb kid who always keeps going in the water, needing help, forcing Hoff to keep saving him. [[spoiler: When the kid gets himself killed after taking a picture of one of the on land piranha. Hoff outright lampshades his death.]]
* UnexplainedRecovery: [[spoiler:Deputy Fallon, who presumably died making a HeroicSacrifice, is at the grand opening of the water park in a wheelchair.]] However, once the piranha show up...
** DisabilitySuperpower, HandicappedBadass: [[spoiler:His titanium prosthetic legs are immune to piranha bites, allowing him to wade into the water and rescue people. He also attaches sawed-off shotguns to said legs.]]
--->''[[PreAssKickingOneLiner Bring me my legs...]]''
* VaginaDentata: A variation on this trope - a baby piranha swims into Shelby's vagina while she and Josh are skinny-dipping. The next day, when the two go to have sex...
* WalkDontSwim: Barry is a terrible swimmer, so when he needs to save Maddy (who's pinned to a drainage pipe) and necessity doesn't provide the skill, he compensates by weighing himself down and walking to her.
