Piranha 3DD is a 2012 American 3D horror comedy film directed by John Gulager and written by Marcus Dunstan and Patrick Melton.

It is a sequel to the 2010 film Piranha 3D, part of the Piranha film series, and stars Danielle Panabaker, Matt Bush, David Koechner, Chris Zylka, Katrina Bowden, Gary Busey, Christopher Lloyd, and David Hasselhoff.

Piranha eggs laid inside a dead cow hatch, and the farmers are killed and eaten.

Maddy, a marine biology student, returns home for the summer to the water park she co-owns and is annoyed to find that the other owner, her stepfather Chet, plans to add an adult-themed section to the water park that allows nudity.

Handcuffed to the van during foreplay and unable to escape, Travis is devoured by piranhas while Ashley, on the roof, calls for help.

Fallon uses a shotgun leg prosthesis to fight the piranhas, while Hasselhoff rescues a young boy named David.

Maddy instructs Barry to begin draining the pools while she attempts to save those still in the water.

Barry sees a human-sized adult piranha swimming toward her and throws a litter trident to kill it.

After Kyle refuses to save her because of his fear of piranhas, Barry, despite being unable to swim, leaps down and brings her to the surface, at which point Maddy is revived.

The film ends with the survivors taking pictures of David's corpse on their phones, with his hysterical mother covered in his blood.

[7] Principal photography began in Wilmington, North Carolina, on April 25, 2011,[8][9] with some filming occurring at the Jungle Rapids water park and the Shaw-Speaks community center.

Soisson also indicated that tax rebates and the variety of geography in North Carolina had convinced them to choose the location over Louisiana.

[20] The film made a small impact during its debut weekend in the United Kingdom, with receipts of just £242,889, placing it at number 8.

The website's critical consensus states: "It strains to up the gore and self-awareness of its predecessor, and—despite some game celebrity cameos—the result is a dispiriting echo of 2010's horror-comedy.

[23] Leslie Felperin of Variety gave the film a negative review, stating, "[The movie] ups the self-parody so much that it's practically a Wayans Brothers spoof, albeit with fewer jokes.
