With its gross-out 3D and heavy doses of gratuitous nudity and gore, last summer's Piranha 3D became an unlikely cult hit. And so, this summer we're treated to Piranha 3DD, a follow-up to the prehistoric fish splatterfest that aims to up the ante from its predecessor. Solution? More girls going wild, more severed body parts, and David Hasselhoff.

Ditching Piranha 3D's Spring Breakers for the grand opening of an adult-themed water park (The Big Wet), Piranha 3DD stars David Koechner as Chet, an ethically-compromised water park owner who inadvertently triggers the sequel's full-scale feeding frenzy. And so it's up to his step-daughter Maddy, played by Danielle Panabaker, and the rest of the park's staff to save their paying customers from becoming fish food. And did we mention it stars The Hoff?

More importantly, how can Piranha 3DD possibly top a movie that reportedly chummed the waters with 75,000 gallons of fake blood a day and featured more body parts flying at the screen than Showgirls? To find out, I put on my 3D glasses and crunched the numbers. After all, someone had to.

(Warning: like the marine biology on display in Piranha 3DD, the following is something of an inexact science. All numbers feature a margin of error of 3.)
