Thanks to IGN here’s the red-band trailer of Piranha 3DD:
“After the terror unleashed on Lake Victoria in Piranha 3D, the prehistoric school of blood thirsty piranhas are back and even more hungry. This time, no one is safe from the flesh eating fish as they sink their razor sharp teeth into the visitors of summer’s best attraction, The Big Wet Water Park.”
I think those blood thirsty piranhas a real human-flesh connoisseurs: they obviously prefer to eat pretty women!
