When the town's water pressure mysteriously drops and two teens go missing – one from a pool and another from a school washroom – the gang begins to suspect something fishy's going on in Whitechapel…or is it something alligator-y? Rory confesses to flushing two baby alligators during last year's locker search at the same time that Benny flushed one of his magic potions. When Erica is attacked at the school car wash, they realize they're now battling two very angry alligators AND their evil mutant mega spawn. And the citizens of Whitechaple are about to be the gators' next meal!
