These things aren't the most graceful flyers mind you, somebody needed to grab a bat or tennis racket and do some serious fish thumping. Not much else to say about this mess, the plot is a serious muddle, I was just overjoyed with Gabby as a character. Never have sex while scuba diving, it upsets the fish. Ugly women can drown in three feet of water. Piranha instinctively go for their victim's throat.
Jamaican nurses are tough hombres.
Half eaten bodies get women in the mood. Making out under a waterfall isn't as fun as it sounds. Piranha see everything through a red filter. Two humans wearing awkward scuba gear can out swim a school of super piranha through the narrow hallways of a sunken ship. Every quartz watch in the world is synchronized.
