Confirmed Harpoon a Fish fish list

Kraken, Megalodon, Crocodon, NIGHTCRAWLER, and POSIONED HEXJAW are named catches supported by Harpoon a Fish's official Roblox badges. This is a partial creature list, useful for identifying real collection targets without borrowing fish names from another game. It is not the complete index that FirstTry advertises as containing more than 1,800 unique fish.

The official Harpoon a Fish badge listing, checked on October 17, 2026, includes a catch badge for each of these names:

  • Kraken: listed under the badge name KRAKEN, with a description recognizing its capture.
  • Megalodon: listed under MEGALODON, also explicitly described as a catch.
  • Crocodon: listed under CROCODON, with a capture description.
  • NIGHTCRAWLER: this exact name appears in both the badge title and its catch description.
  • POSIONED HEXJAW: this is the spelling used by the official badge, including the unusual spelling of “POSIONED.”

These records establish named catches associated with this exact Roblox game. They do not establish each creature's location, required weight, rarity tier, or encounter chance.

Why five names are not the whole index

The developer's game description advertises over 1,800 unique fish, but it does not enumerate them. A badge list serves a different purpose from an in-game collection index: it records achievements, and only some of those achievements name particular creatures.

For example, Stranded, New Pet, and Bait Crafter also appear in the badge response. Those titles are achievements, not evidence of fish species with those names. Including every badge title in a fish list would create false entries.

Likewise, the creature badges do not explain whether the advertised index total counts base species, variants, or another combination. The available information does not support turning that total into a complete species checklist.

How to use the list while collecting

Use these five confirmed names as reference points when comparing catches and any collection entries visible in your game. Record a creature's displayed name and any variant separately, and keep any location you observe as your own session note until it is confirmed more broadly.

FirstTry describes heavier characters sinking deeper to discover additional sea monsters. It also describes aiming a harpoon, firing, timing reels, and placing caught fish in an aquarium to grow. Those are general collection mechanics; they do not supply a special bait recipe or guaranteed depth for any creature above.

Badge award totals should not be read as fish spawn rates. They count badge awards, and the response does not provide the encounter data needed to calculate a creature's probability of appearing.

FAQ

Is this the complete Harpoon a Fish fish list?

No. It is a sourced partial list of five creatures named by official catch badges. The developer advertises a much larger index without publishing its complete contents in the checked description.

Where do Kraken and Megalodon spawn?

Their catch badges confirm the creatures' names, but the descriptions do not give spawn locations, timers, or depth requirements. A precise route cannot be established from those badges alone.

Is it Poisoned Hexjaw or POSIONED HEXJAW?

The official badge uses POSIONED HEXJAW. This guide preserves that spelling so you can match the entry to the source, rather than silently changing the name.

Which of these creatures is the rarest?

The checked official records do not provide comparable spawn probabilities or rarity tiers. Badge award counts alone cannot establish a reliable rarity ranking.
