Here's the first footage from Piranha 3DD, the sequel to the fish movie that bit off a man's penis on camera! And this time, the Piranhas are traveling through the sewer system, eating up all the folks lounging in their pools. Their end game? Invading a busty water park. The film — which was penned by Saw 3D writers Marcus Dunstan and Patrick Melton — should be arriving in theaters sometime in 2012. This video was screened at the Scream Awards.
