Harvester is a giant great white shark, that is tied to the legend of Pinocchio.
Harvester resembles a Megalodon the Prehistoric Shark with the Long Serpentine Tail.
Harvester is first seen swimming around the ship wrecks when he spots Marina (Mermaid) and Flounder swimming about. He immediately attacks Flounder and begins a chase going through Ariel's Grotto which the Harvester accidently destroyed it before king triton did which caused Ariel down in tears. However, he ends up hiding in the cave as the sign in front of the Trench says Terrible Dog Fish ahead.
