The latest wave of content for Fisch adds a hybrid Halibut Harpoon, a returning weekend Black Market, and a free developer gift you can claim right away. There are also new movement tools, mastery quests, and cosmetics tied into the same update, plus a Double Luck weekend running alongside it.
Quick answer: Unlock the Halibut Harpoon by finishing Dr. Monty’s questline in The Deep, then open the “A Gift From The Developers” pop-up and press Claim while it is still available.

How to get the Halibut Harpoon in Fisch
The Halibut Harpoon is a hybrid piece of gear that works as both a fishing rod and a harpoon gun, and it carries a unique passive minigame that sets it apart from standard harpoons. Like other harpoon guns, it is aimed at Roaming Fish and uses a pull minigame to reel targets in.

Once the questline wraps up, the Halibut Harpoon is added to your equipment bag, where you can swap to it using the category selector alongside your rods and spears.

Add to Google Preferences →Claim the free developer gift
A free reward labeled “A Gift From The Developers” is available for a limited time. When the pop-up appears from “The Fisch Team,” select Claim to collect everything inside. Once claimed, the window can be closed and the items land directly in your inventory.
The gift bundles several cosmetics and consumables together:
- goober Bobber
- WorldLamp (Lantern)
- Companion Skin: Large Sleepy
- Stock Car
- silly stone guy
- 10+ Companion Candy
- 10+ Shell
Because it is a temporary claim, collect it early rather than waiting, since the pop-up will not stay available indefinitely.

When the Black Market restocks
The Black Market is a limited-time shop that appears in the Shady Bazaar during real-world weekends. Stock is shared globally, and quantities are limited per player rather than per server, so once you buy an item it counts against your personal allotment.
The restock lands on Sunday and shows up an hour after the update goes live. It also appears a second time roughly half a day later to cover different time zones, giving players two windows to shop before the merchant vanishes. On weekdays the shopkeeper is asleep behind the counter and sells nothing.
Items seen in the current rotation include a mix of high-cost collectibles and cheaper cosmetics:
| Item | Price |
|---|---|
| Sword of Light | C$117,500,000 |
| Money Bag | C$13,333,333 |
| Black (Boat) | C$5,000,000 |
| Alpaca Plush | C$2,512,525 |
| Chair | C$100,000 |
| Bunch of Balloons | C$10,000 |
Since the biggest items run into the millions, save up a large amount of C$ before the weekend if you want a shot at the rarest picks.
Stabilizer Chip for the Survey Device
The Stabilizer Chip is a toggle module for the Survey Device that improves underwater movement by stopping you from sinking. With it enabled, navigating deep areas becomes far more controlled.
You get it in one of two ways. Players who already completed Nereus’s quest receive the chip automatically. Everyone else can obtain it while fixing the Survey Device.

Plague Reaver mastery quests
The Plague Reaver weapon gains three new mastery quests. Completing them increases the weapon’s power, so work through all three if the Plague Reaver is part of your setup.
Lemonade Serenade skins from the Sun Shell merchant
The Sun Shell merchant is offering new skins for the Lemonade Serenade. These are cosmetic changes to the weapon’s look, so they are optional but worth grabbing if you want to customize its appearance.

Double Luck weekend and active code
A Double Luck weekend event is running, which is the ideal time to fish for rarer catches while the multiplier is live. Pair it with the current promo code for an extra reward:

Redeem it from the in-game codes menu. Codes can expire without warning, so enter it soon rather than saving it for later. With the harpoon quest, the free gift, and the weekend Black Market all live at once, the priority order is simple: claim the gift first, finish Dr. Monty’s questline for the Halibut Harpoon, then bank enough C$ to shop the Sunday restock.
