As drawn to humongous hooters as the target audience for this outrageous sequel to the 2010 horror comedy, the titular undersea monsters return to feast on the flesh of buxom females (and guys, too, if they must) spending the summer at a wet-'n'-wild waterpark. It's up to a pretty biology student (Danielle Panabaker) and her friends to stop the tooth-in-cheek massacre! Co-stars Katrina Bowden, Christopher Lloyd, Ving Rhames, Gary Busey, and─yes─David Hasselhoff as himself. AKA: "Piranha 3DD." Not in 3D. 83 min. Widescreen; Soundtrack: English.
