Last week we covered news that the Piranha 3D sequel was delayed until November 23rd and that Joel Soisson had been brought in to re-write the script. Bloody Disgusting now claims to have the first plot details for Piranha 3DD:

"...the piranha this time make their way into swimming pools, pipes, plumping and such at a newly opened waterpark named 'Wilderness Waters'! The race is on to save the town from these flesh-eating creatures that are leaving a bloodbath in their wake"

That sounds like a good location for a crazy sequel. Unlike the first film, the sequel will be shot in REAL-3D, as opposed to being post-converted. Filming will begin soon, so we'll be on the lookout for casting details and will post them when announced.
