What is Harpoon a Fish?

Harpoon a Fish is a multiplayer harpoon fishing simulator on Roblox from FirstTry. You start on a small island, dive into layered ocean zones, aim and fire at marked sea creatures, and finish every catch with a timed reel. The collection spans more than 1,800 fish, from shallow commons to rare and legendary monsters in the deepest water.

Progress comes from more than a stronger harpoon. Caught fish can become aquarium pets that grow and evolve, while eating at the Mukbang table adds weight that lets your character sink into deeper 300 m bands. EXP, Ruby Keys, equipment slots, bag space, and bait each solve a different part of the loop, so the fastest route is to finish one clear goal at a time.
