Later, Billy goes for another swim and knows it can't be seaweed attacking him because seaweed doesn't have claws. So he screams and struggles but soon he sees the giant head of the Monster break water in a miniature tsunami and it roars at him but he realizes it was just a nightmare.
Billy goes for a morning swim but is almost eaten by a hammerhead shark and saved by a legendary mermaid.
Afterwards, the Sea Monster is not seen at all but reappears in the end, where it breaks the surface when Billy goes off looking for the mermaid. Billy sees the Monster and screams, wondering if anyone would believe him now.
