Two massive prehistoric monsters are better than one, so Cyril travels to the dangerous swamps and wild coast of Louisiana to track down a pair of predators that hunt its murky waters. From the remote bayous to the Gulf of Mexico, he won't stop until he catches a huge shark and an armored alligator gar. But they aren't the only monsters he needs to worry about - he'll also have to brave the rattlesnakes and alligators that haunt the swamp.
