Harpoon a Fish (Roblox): Official Code and How It Works
Harpoon a Fish is a Roblox fishing experience from the group FirstTry. As of 11 November 2026, the official description prints one code, MONSTER, and states a reward: +3k XP and +3 Ruby Keys. The same page also lists a four-step “How To Harpoon” loop and says the index has over 1,800 unique fish. This guide sticks to that official page and Roblox’s public games data.

Harpoon a Fish codes (November 2026)
Last checked: 11 November 2026. The official Roblox game description opens with this line: “Use Code: MONSTER to get +3k XP and +3 Ruby Keys.”
| Code | Reward | Status |
|---|---|---|
| MONSTER | +3k XP and +3 Ruby Keys (official page) | Active |
The official page does not say whether MONSTER is limited to new players, how long the XP lasts, or what a Ruby Key is used for. We will not invent those details. If the developer later adds more official codes or a fuller reward line, we will update this table.
There are no expired official codes in our table, because we do not reconstruct older lists the official page no longer shows.

How to redeem the MONSTER code
The official description tells you to use the code and what it grants, but it does not say which menu to open. Do not trust a step-by-step path we have not confirmed.
What you can do from the official information:
- Open Harpoon a Fish on Roblox.
- In the lobby or HUD, look for a Codes, Gift, or similar control.
- Type `MONSTER` exactly as it appears on the official page.
- If it fails, check the official description again. Codes can be removed without notice.
Avoid third-party “code generators” or downloads. Only the code printed on the official page should be treated as real.
What is Harpoon a Fish?
Harpoon a Fish (listed on Roblox as “[🦖] Harpoon a Fish”) was created on 28 August 2026, 18:31 UTC by the Roblox group FirstTry. Roblox files it under Simulation / Tycoon. Servers hold up to 6 players.
The official description’s pitch is: get fat and sink deeper to discover and catch new sea monsters, and fill out an index with over 1,800 unique fish. It also says you can harpoon other players’ fish — “Only one can catch the trophy” — and that you can evolve a fish to grow “the BIGGEST and RAREST sea monster you can find,” with a warning that “danger lurks the deeper you go.”
At the time of our 11 November 2026 check of Roblox’s public games and votes APIs, the experience had 17,697,731 visits, 13,258 people playing, and 111,156 up votes / 3,191 down votes. The listing had been updated the same day (11 November 2026, 10:43 UTC). Those numbers move constantly; they are a snapshot, not a live ticker.
How to harpoon, in official wording
The official description includes a short “[How To Harpoon]” list:
- Aim at your target and fire.
- Time your reels to pull in the fish.
- Test your skill and steal from others.
- Put caught fish in your aquarium and grow your new pet.
The official page does not list button bindings, a full fish rarity table, drop rates, or how evolution is started. “+3k XP” and “+3 Ruby Keys” are the only reward amounts printed on the official page we checked. If another site publishes a deeper drop table without an official source, treat that as unverified.
