Fish It! Codes (October 2026) — New & Working

October 15 re-check (12 sources): the newest hard verifications — Roblox Den and KodeGG, both checked October 14 — delist most of the older ladder, leaving MERDEKA and ELEMENTAL26 as the only rock-solid actives. MUTATION2, YEEHAW, DIVING, POTIONSSS, CONTRA and WORMHYPE now sit in the disputed-pending lane (Roblox Den marks Check while KodeGG/The Click/PlayPatch’s in-game test say alive). UrGameTips’ claim that 16 codes “started working again” on October 14 has no second-source corroboration — treat the list below via the live codes page, and report anything that still redeems.

Fish It! just shipped its big October expansion — new fish, the fishing journal, more islands — and while no brand-new code dropped with it, the code vault here is one of the deepest on Roblox: after the October 15 twelve-source re-check, 2 codes stand rock-solid active with 6 more in the disputed-pending lane — the live codes page is always current. This list stays synced with our Fish It! codes page — every entry carries its reward, source and last-verified date.

The working codes this month

The headliners, confirmed by PCGamer (October 12), Eurogamer (October 8) and KodeGG simultaneously:

• MERDEKA — the Kerupuk lantern, the one code all four trackers agree on
• ELEMENTAL26 — the newest add: Ember Heart per Eurogamer (KodeGG’s automated feed logged it with Mutation II Potions — reward text differs, the code works either way)
• The potion core: POTIONSSS and MUTATION2 (2x Mutation II each), DIVING, PIRATEMAJA, 3BILLION, CRYSTALS (Luck II Potions), TRAVEL and BLAMETALON (Luck I + II mixes), SHARKSSS (Mutation I + Luck II)
• The keepsake shelf: YEEHAW (Cowboy Hat Halo), 1M_GOAL (Community Rod), GO2026 and NEWYEARLANTERN (skins), CRESCENT (bait skin), GIFTGIVING, FREEPRESENTS, LUCKYTOTEM, FREECRYSTAL, EASTER2026, 500K_GOAL_FXCB
• The Leviathan set: THEDEN, LEVDEN, SCALE2, SCALEREFUND — each 1x Leviathan Scale, and each only pays if you have completed the Leviathan quest

Why our list is bigger than some others

Here is the honest part: tracker sites disagree about this game’s older codes. Eurogamer’s October 8 pass verified only MERDEKA and ELEMENTAL26 as active and archived everything else; PCGamer’s October 12 re-check keeps the whole ladder live; KodeGG’s automated feed splits the difference. Our rule is most-recent-check priority with multi-source weighting — so codes confirmed active by two or more of the latest passes stay active, and single-source stragglers (like CONTRA) sit in pending until a second source shows up. Nothing here is invented; every entry names its sources.

Level 10 before anything

Fish It! gates code redemption behind Level 10 — paste a code under-leveled and you get the ‘You need to be Level 10’ warning instead of rewards. A few minutes of fishing and selling clears it. The full routine lives in our redeem guide.

Bookmark before the next expansion

The developer ties codes to updates, visits milestones and holidays — the October expansion shipped without a fresh code, which historically means the next one is close. Bookmark the codes page and check back right after each patch.
