Kohana Expansion in Fish It – What’s New?

What the Kohana Expansion actually is?

The Kohana Expansion is more than “a new zone” — it’s a full refresh of Kohana Island and its surrounding content. The official [UPD] Fish It! post on X/Twitter summarizes it like this:

• Volcano Event: every 4 hours, temporary lava boosted fishing zones appear around Kohana.
• Kohana Island Revamp: updated layout with new areas to explore.
• Fish Bounties: bounty boards to hunt specific fish for rewards.
• Event Quest System: new quest challenges and rewards.
• Lucky Charm: increases your general luck when fishing.
• The Lava Charm: improves your odds for Magma Shark.
• Hazmat Descent: a special suit needed for a locked underground area.
• Exclusive Event Boat: a limited‑time boat for the event.
• Crescendo Scythe Skin: a limited rod skin with a custom bobber skin.

On top of that, guides from Roonby, RobloxPulse, and Techwiser add crucial details: a full quest line for the Hazmat Suit, special magma/lava fish counters, bounty payouts up to ~880,000 coins, and new secret fish like the Ancient Magma Whale that reward the Inferno Core rod skin.

When is the Kohana Expansion live?

According to Deltiasgaming’s timing table, the Kohana Expansion went live in most regions on January 31 – February 1, 2026, and is scheduled to end around February 6, 2026. IGN’s code guide also explicitly mentions the Kohana Expansion launching on January 31.

If you’re seeing this after early February, double‑check in‑game events and official Fish It social channels to see if any Kohana content is still active or has been extended.

How to get to Kohana and the Volcano?

From the Kohana wiki and SportsRant’s guide:

• Kohana is an island with:
  • Tim’s Rod Shop (several strong rods).
  • A Fish Merchant.
  • A waterfall that leads into a cave – that cave is the entrance to Kohana Volcano.

Basic route:

1. Go to Kohana Island by boat.
2. Follow the water channel on the island toward the cave entrance at the end.
3. Enter the cave – you’ll emerge in the Kohana Volcano area.

Inside the volcano, you’ll find:

• Hazmat Leader (Hazmat Descent quest).
• Bounty boards (new fish bounties).
• Charm stations (Lucky Charm, Lava/Magma Charm).

Kohana Volcano Event – 4‑Hour Eruption Cycles

How the Volcano Event works?

Every 4 hours, the Kohana Volcano erupts, spawning temporary “lava boosted” fishing zones around Kohana. These zones:

• Only exist for a short time.
• Appear in random spots on the water.
• Give massively improved fishing rates when you fish inside them.

RobloxPulse adds that during an eruption, magma rocks create “Rings of Fire” on the ocean surface that give:

• 2x Luck boost
• 2x Mutation chance

…for anyone fishing inside them.

How to track eruptions?

You can track the eruption timer:

• On the digital signboard near the volcano base / main island area.
• On the sign or timer in the water channel area on Kohana Island.

Best strategy for eruption windows

• Save high‑value bait (e.g., event baits, high‑tier potions) for eruption windows.
• Be ready in your boat when the timer gets low so you can zip to lava zones as soon as they spawn.
• Equip your best luck rod + Lucky Charm + a Luck Potion if you have one – buffs stack.
• Focus on:
  • Magma/Lava‑tagged fish for quests.
  • Mythical and Secret targets like Magma Shark and Ancient Magma Whale.

If you want to understand more about stacking luck potions, rods, and special items, our All Fish It Charms Guide goes deep into how to combine these boosts.

New Bounty System in Kohana – How It Works?

Where bounties are and why they matter?

The official update post adds “Fish Bounties: new bounty boards let you hunt specific fish and turn them in for rewards.” Roonby and Techwiser give more concrete details:

• Bounty boards are located in the Kohana area (near the front / main island).
• You:
  • Check the board for target fish and bounties.
  • Catch the bounty fish.
  • Turn it in at the board to receive coins instantly, no need to sell manually.

Roonby mentions that some bounties pay up to 800,000–880,000 cash, making this one of the strongest coin‑farm methods in the game right now.

Bounty rarities and rod skin tie‑ins

Techwiser explains that bounties come in different rarities (colors), and that:

• Completing an Epic Bounty unlocks the Magma Hook rod skin.
• Bounty boards refresh daily, so if you don’t see Epic bounties one day, check again the next.

This is a nice synergy:

• Grind bounties for money.
• In the process, unlock the Magma Hook skin as a “bonus” for doing what you’d be doing anyway.

My recommended bounty strategy

1. Every day when you log in, check all Kohana bounty boards.
2. Prioritize:
   • Bounties with the highest coin reward.
   • Bounties that target fish you can catch efficiently with your current gear.
3. During Volcano Events, focus on:
   • Magma/Lava bounties, since eruption windows give better mutation and magma fish rates.
4. Once you unlock the Epic bounty for the Magma Hook skin:
   • Treat that bounty as a high‑priority side goal since it’s a free, cosmetic reward.

Hazmat Suit (Hazmat Descent) – Unlock & Use

Why you need the Hazmat Suit?

The Hazmat Suit is tied to the “Hazmat Descent” feature in the official update notes:

• A special suit that allows access to a locked underground area beneath the volcano.

Techwiser’s revamp guide is more specific:

• You can’t enter the deeper Volcanic Cavern (endgame lava pools) without the Hazmat Suit.
• Trying to enter the underground area without the suit causes heat damage and prevents access.

Quest requirements (Hazmat Leader)

According to Roonby:

• The Hazmat Leader NPC gives a quest to unlock the Hazmat Suit.
• Requirements include:
  • Fishing 1,000 times in the Kohana Volcano area.
  • Only fish labeled “Magma” or “Lava” count; normal fish do not progress the quest.

Techwiser adds an extra condition:

• You also need to collect 2,000,000 coins as part of the requirements for the “Suited Up” quest (Hazmat Suit reward).

So in total, expect:

• A long grind of magma/lava fish in the volcano.
• A coin requirement to prove you’re ready for endgame content.

How I’d grind the Hazmat Suit efficiently?

Step‑by‑step:

1. Get to Kohana Island and unlock the volcano cave.
2. Use:
   • Your best luck rod.
   • Lucky Charm / Lava Charm if you have them.
   • Luck Potions from our codes pages (see section on codes below).
3. Fish inside the Volcano area and:
   • Focus on fish with the Magma or Lava tag so they count toward the 1,000 requirement.
4. Track your coin total so you can hit 2,000,000 as you fish.
5. Return to Hazmat Leader once both conditions are met to claim the Hazmat Suit.

After that, use the teleport near the volcanic hole to reach the Volcanic Cavern and fish in the deepest lava pools for the rarest content.

New Charms: Lucky Charm & Lava/Magma Charm

Lucky Charm – general luck boost

The official update post describes Lucky Charm simply as something that “increases your luck when fishing.”

Based on how other charms work (from our charms guide):

• Charms give targeted multipliers and can be equipped from your inventory Charms tab.
• Lucky Charm is likely best used:
  • During Volcano Event zones.
  • When grinding for high‑rarity Kohana fish.
  • While working on bounties or index completion.

I recommend:

• Equip Lucky Charm whenever you’re fishing for:
  • Legendary, Mythic, and Secret fish.
  • High‑value bounty targets.
• Stack it with:
  • A high‑luck rod.
  • A Luck Potion (you can grab extra potions from Fish It codes on our site).ofzenandcomputing

Lava/Magma Charm – Magma Shark helper

The X/Twitter post says:

• The Lava Charm “boosts your odds of catching a Magma Shark.”

NerdsAndChalk’s Magma Charm guide adds:

• The charm increases your chances of catching the Magma Shark specifically – it does not help with other fish.
• You buy it inside Kohana Volcano at a charm station for 20,000 coins.
• Equip it from your inventory’s Charms tab.
• It’s most effective when you’re already in the deep Kohana volcano zone that requires the Hazmat Suit.

So:

• Only equip the Lava/Magma Charm when you’re actively hunting Magma Shark.
• Use it together with:
  • Your best luck rod.
  • Potions and any event/eruption luck boosts.

If you want a full breakdown of all charms (Bone, Algae, etc.), including where they live and how to use them, check our All Fish It Charms Guide.

Kohana Island Revamp – New Layout & Areas

Techwiser’s revamp guide does a great job summarizing how Kohana Island changed:

• The updated POI is now split into three main parts:
  1. The Main Island
  2. The Kohana Volcano
  3. The Volcanic Cavern

1) The Main Island

This is your “safe” area:

• Typical tropical fishing around docks and coasts.
• Most fish from before the revamp are still here; it’s a reliable coin farming zone.
• New quest NPCs have been added in the dock area with decent rewards.

The SportsRant Kohana guide lists typical Kohana Island fish, including:

• Common: Reef Chromis, Jennifer Dottyback, Zoster Butterfly, Boa Angelfish.
• Uncommon: Shrimp Goby, Bluemato Clownfish, Banded Butterfly.
• Rare: Fire Goby, Kau Cardinal.
• Epic: Longnose Butterfly, Sushi Cardinal.
• Legendary: Bumblebee Grouper, Lobster.
• Mythic: Prismy Seahorse, Loggerhead Turtle.
• Secret: Lochness Monster (extremely rare).

This area is great for:

• Early to mid‑game coin farming.
• Preparing gear and coins before you start tackling the volcano.

2) The Kohana Volcano

The volcano sits inside Kohana’s mountain and is accessed through the waterfall cave.

Here you’ll find:

• Hazmat Leader and related quests.
• Bounty boards.
• Charm stations.
• Magma/Lava fish tied to quests and charms.

SportsRant lists some volcano fish like:

• Common/Uncommon: Volcanic Basslet, Magma Goby, Lava Butterfly.
• Rare: Volsail Tang, Rockform Cardinal.
• Epic: Firecoal Damsel.
• Legendary: Lavafin Tuna.
• Mythic: Blueflame Ray.

These fish often sell for more and are ideal once you have a solid luck rod and maybe a charm equipped.

3) The Volcanic Cavern

This is the true endgame of the Kohana Expansion:

• You can’t enter without the Hazmat Suit.
• Use the teleport prompt near the volcanic hole once you have it.
• Here you can find:
  • Magma Shark and other high‑value magma fish.
  • The Ancient Magma Whale, a secret-tier fish with a 1 in 5 million chance.

RobloxPulse also mentions:

• A “Secret Tier Fish” in the Volcanic Cavern with a sell value of 2,000,000+ coins.
• A “Sealed Stone Gate” that, for now, is a teaser/placeholder for future content; you can fish the lava pools in front of it but cannot go through.

New Secret Fish & Rewards – Ancient Magma Whale, Skins, and More

Ancient Magma Whale – hardest free reward in the game

Techwiser’s rod skin guide and revamp guide describe the Ancient Magma Whale as:

• A secret fish added as part of the Kohana Volcano expansion update.
• Found only in the Kohana Volcano area.
• Has a 1 in 5,000,000 chance to catch.
• Requires a very heavy rod (Element or Diamond Rod) to actually reel it in.
• You cannot boost its odds with charms – it stays at 1 in 5 million regardless.

Catching it unlocks:

• The Inferno Core rod skin, one of the rarest free skins in the game.

So, if you’re hunting the Inferno Core:

• Make sure you have:
  • Hazmat Suit for deep cavern access.
  • Element or Diamond Rod (or similar heavy endgame rod).
• Fish in the right lava pools during eruptions and high‑luck events for best results.

Secret Tier fish with huge coin value

RobloxPulse notes:

• A “Secret Tier Fish” in the Volcanic Cavern lava pools can sell for over 2,000,000 coins, making it one of the most valuable catches in the game right now.

Roonby also mentions:

• A secret fish in the Kohana Volcano index with a value up to 5,000,000 coins.

Given the wording differences, it’s likely that:

• There is at least one high‑value secret fish in the volcano/cavern pools.
• Exact value and name might differ based on how devs label or buff fish, so expect prices and rarities to be tweaked over time.

Other rewards tied to the expansion

• Magma Hook Rod Skin:
  • Unlocked by completing an Epic Bounty from a Kohana bounty board.
  • Relatively easy to get if you keep checking the board.
• Crescendo Scythe Skin:
  • Limited rod skin with a custom bobber skin.
  • Listed in the official X/Twitter post as an event‑exclusive reward.
• Exclusive Event Boat:
  • A limited‑time boat available during the Kohana event to help you travel to the expansion more quickly.
• Inferno Core Rod Skin:
  • Reward for catching the Ancient Magma Whale (the insane 1 in 5M secret).

For rod progression and high‑luck setups, our Fish It Cursed Kraken guide and Magma Shark guide show how late‑game gear and server luck events interact — those strategies also help in Kohana’s endgame zones.

Are There New Fish It Codes for the Kohana Expansion?

Right now, the answer is: no specific Kohana‑only codes.

Roonby explicitly states:

• “No new codes in this update yet!” when talking about the Kohana Expansion.

However, there ARE still working general Fish It codes that you can use to stock up on Luck Potions and other helpful items while grinding Kohana.

Active Fish It codes (general)

From recent code updates by IGN and PC Gamer, here are some key working codes as of early February 2026 (you must be at least level 10 for most):

• PIRATEMAJA – 2x Luck II Potion
• DIVING – 2x Luck II Potion
• WORMHYPE – high‑level requirement (often level 100+), special reward

Note: code lists are changing constantly. IGN and PC Gamer show some codes as active in one snapshot and expired in another, so:

• Always double‑check against our Fish It Codes pages, which are updated regularly with the latest working lists.ofzenandcomputing+1

How to redeem Fish It codes?

IGN and Eurogamer describe the same process:

1. Start Fish It and complete the tutorial.
2. Fish until you reach at least level 10 (sometimes level 11 in practice).
3. Click the “Store” icon at the top (the red basket).
4. Scroll to the bottom of the Exclusive Store.
5. Enter your code in the Redeem Codes box and hit Redeem.

If a code doesn’t work:

• Make sure there are no extra spaces.
• Check that you’re above the level requirement.
• Confirm it hasn’t expired – some codes like 3BILLION and EXPANSION are already marked as expired on IGN.

Where to watch for future Kohana codes?

Eurogamer notes that Fish Atelier usually shares new codes via the official Discord server. Diorama’s guide also highlights the official Discord as the main place for announcements and code drops.

So if you want to catch any future Kohana‑specific codes:

• Join the official Fish It Discord (linked from the X/Twitter bio).
• Follow the official Fish It X/Twitter account.x

Bookmarking this page and our codes pages is also smart – I’ll keep updating key details as new info drops.

Full Progression Path Through the Kohana Expansion

Here’s a visual “flow” of how you should move through the Kohana content, from your first visit to hunting secrets like the Ancient Magma Whale:

Arrive at Kohana Island

Grind Main Island fish & quests

Save coins, upgrade rod, unlock volcano cave

Enter Kohana Volcano

Complete Hazmat Descent quest

Teleport to Volcanic Cavern

Hunt Magma Shark & bounties

Try for Ancient Magma Whale & Inferno Core skinPro Tips & Common Mistakes in Kohana

Pro strategies

• Always time your fishing around eruptions:
  • Every 4 hours, the volcano creates special lava zones with 2x luck and mutation chance.
• Use bounties as your main coin engine:
  • High‑pay bounties (up to ~880,000 coins) out‑class regular selling for many players.
• Stack every boost you can:
  • Best luck rod + Lucky Charm/Lava Charm + Luck Potion + eruption buff = massive odds improvement.
• Don’t ignore server luck events:
  • Admin mega luck events drastically increase rare and secret fish spawns (same principle we saw with the Cursed Kraken).
• Plan your Hazmat Suit grind:
  • Focus only on Magma/Lava‑tagged fish in the volcano, and make sure you’re also tracking the 2,000,000 coin requirement.

Common mistakes to avoid

• Trying to enter the Volcanic Cavern without the Hazmat Suit:
  • You’ll just take heat damage and get denied access.
• Using Lava/Magma Charm when you’re not targeting Magma Shark:
  • The charm only helps for Magma Shark – it’s wasted on general fishing.
• Grinding in the volcano with bad gear:
  • You’ll spend way more time than necessary. Upgrade your rod and bring potions and charms before committing to long sessions.
• Ignoring bounty boards:
  • Some players sell fish normally and miss out on hundreds of thousands of free coins from bounties.
• Assuming every shiny fish is “new”:
  • Many “new” fish were already around (e.g., Kohana Island fish like Prismy Seahorse); the expansion added more magma and secret fish instead.

Frequently Asked Questions

When does the Kohana Volcano erupt in Fish It?

The Kohana Volcano erupts every 4 hours. You can track the exact time using:

• The digital signboard near the volcano base.
• Timers placed in the water channel area on Kohana Island.

How do I get the Hazmat Suit in Fish It?

To get the Hazmat Suit (Hazmat Descent):

1. Go to Kohana Island and find the volcano cave.
2. Talk to the Hazmat Leader NPC inside the volcano.
3. Complete his quest requirements:
   • Fish 1,000 times in the Kohana Volcano area (only Magma/Lava fish count).
   • Also earn 2,000,000 coins as part of the “Suited Up” quest.
4. Once you complete the quest, you’ll unlock the Hazmat Suit, which lets you enter the Volcanic Cavern through the teleport.

What is the Ancient Magma Whale and how do I catch it?

The Ancient Magma Whale is:

• A secret-tier fish added with the Kohana Volcano expansion.
• Found only in Kohana Volcano (usually deep lava pools in the Volcanic Cavern).
• Has a 1 in 5,000,000 catch rate.
• Requires a heavy rod (Element or Diamond Rod) – you literally cannot reel it in with weaker rods.
• You cannot boost its odds with charms; the chance stays 1 in 5M no matter what.

Catching it unlocks the Inferno Core rod skin, one of the hardest free cosmetic rewards in the game.

What do Fish Bounties do in Kohana?

Bounties are special fish‑hunting requests:

• Bounty boards around Kohana show target fish and their rewards.
• When you catch a bounty fish and turn it in, you instantly receive coins (no need to sell the fish normally).
• Some bounties pay up to ~800,000–880,000 coins, making them one of the best money‑farming systems in the game right now.
• Completing an Epic bounty also unlocks the Magma Hook rod skin.

How do I get the Magma Hook and Inferno Core rod skins?

• Magma Hook Rod Skin:
  • Go to a Kohana bounty board.
  • Find and complete an Epic Bounty (they refresh daily).
  • Claim the reward – you’ll get the Magma Hook skin.
• Inferno Core Rod Skin:
  • Catch one Ancient Magma Whale in the Kohana Volcano.
  • The odds are 1 in 5,000,000 and you need a heavy rod (Element or Diamond) – charms do not improve this.
  • Once caught, you unlock the Inferno Core skin.

What does Lucky Charm and Lava/Magma Charm do?

• Lucky Charm:
  • Increases your luck when fishing, as per the official update notes.
  • Best used for general rare fishing and bounties, especially during eruptions.
• Lava/Magma Charm:
  • Specifically boosts your odds of catching the Magma Shark.
  • Bought inside Kohana Volcano for 20,000 coins at a charm station.
  • Only equip it when you’re actively targeting Magma Shark, as it doesn’t help other fish.

Are there any new Fish It codes for the Kohana Expansion?

No. As of early February 2026:

• Roonby explicitly says: “No new codes in this update yet!”
• Official posts and code roundups (IGN, PC Gamer, Eurogamer) show only general codes, not Kohana‑exclusive ones.

That said, you should still:

• Use existing active codes (like PIRATEMAJA and DIVING) to stock Luck Potions for Kohana grinding.
• Watch the official Fish It Discord and X/Twitter for any future Kohana‑specific codesx .

What’s the best way to make money in the Kohana Expansion?

For most players in 2026, the best combo is:

1. Check bounty boards every day and prioritize high‑coin bounties (up to ~880,000).
2. Fish during volcano eruptions in lava boosted zones:
   • 2x luck and mutation chances mean more high‑value catches.
3. Use Lucky Charm + Luck Potions + a strong luck rod to:
   • Catch valuable mythic and secret fish like Magma Shark and Ancient Magma Whale.
   • Turn in secret fish with multi‑million coin values when you get lucky.

Do I need a special rod for Kohana?

You don’t absolutely need a special rod to start:

• On Kohana Island’s main docks and coasts, basic rods work fine for early fish.
• But once you’re in the Volcano and especially the Volcanic Cavern, you’ll want:
  • A high‑luck rod for consistent rare and mythic catches.
  • A heavy rod (like Element or Diamond) to handle secret fish like the Ancient Magma Whale.

SportsRant also notes that while basic rods work on Kohana Island proper, the Lava Rod or higher luck rods are best for the volcano area.

Where is the Kohana Volcano exactly?

• Kohana Island is a zone with its own docks, waterfall, and cave.
• Follow the water channel from the main island until you reach the cave entrance at the end.
• Enter the cave – that leads into the Kohana Volcano, where you’ll find Hazmat Leader, bounty boards, and charm stations.

Conclusion

The Kohana Expansion in Fish It is easily one of the most substantial updates we’ve seen in 2026, completely revitalizing the late-game grind. Whether you’re here to exploit the new Bounty Boards for massive coin gains, brave the 4-hour Volcano eruptions for mutation boosts, or endure the long grind for the Hazmat Suit to hunt the Ancient Magma Whale, there’s something for every type of player.

Just remember: efficiency is key. Time your fishing sessions with the eruption cycles, keep your Lucky Charms equipped, and don’t sleep on those daily bounties. While we didn’t get any brand-new Kohana codes this time around, using your stockpiled Luck Potions will make the journey significantly smoother.

I’ll be keeping a close eye on the official Discord and Twitter feeds for any surprise code drops or balance changes to the Volcanic Cavern, so make sure to bookmark this guide and check back regularly. Good luck out there on the lava, and may you reel in that 1 in 5 million secret
