To beat the Blue Shark in How to Fish, buy a Standard Boss Lure, hook the shark on Island 3, fight it with upgraded firepower while using the coconut trees for space, then carry it back to the Grillmaster to unlock the grill.
How to Fish, the physics-based co-op fishing-and-shooting game Dazed Games released on Steam on August 20, 2026, hides a real boss fight behind one of its cooks. On Island 3, the Grillmaster won’t light his grill until you drag a shark to his feet, and the Blue Shark is the catch that clears that job. It’s a short fight if you show up with the right lure and enough firepower.
The Blue Shark and its Grillmaster quest
| Detail | Value |
|---|---|
| Health | 100 |
| Sell value | $300 |
| Weight | 70.0 |
| Lure needed | Standard Boss Lure ($280) |
| Quest role | Grillmaster grill unlock (Island 3) |
The Blue Shark is a 100-health creature you fish up around Island 3, and it exists mainly to satisfy one objective: the Grillmaster asks you to bring him a shark, and the Blue Shark is the one you reel in there. It isn’t a farming target. It sells for only $300 and weighs 70.0, so the payoff isn’t the sale — it’s the grill you earn for turning it in.
Gear and lures to bring
You can’t hook the Blue Shark with an ordinary lure. Buy a Standard Boss Lure for $280 before you head out — that’s the bait that brings the shark to the surface. One is all you need to plan around, since island boss lures are always consumed on use rather than having a chance to survive like the smaller lures do.
Key For firepower, a maxed Uzi is enough to take the shark’s 100 health down cleanly, so treat that as your benchmark rather than a hard requirement — anything with comparable damage and a manageable reload works. If you’ve already bought extra inventory or hotbar slots by this point, bring them along so you can carry more healing fish into the fight; those slots are worth picking up as you progress regardless.
Buy just one Standard Boss Lure — island boss lures are consumed every single time, so there’s no reason to stock extras before the fight.
How to beat the Blue Shark and hand it in
Reach Island 3
Travel to the island where the Grillmaster is waiting and the Blue Shark spawns.
Cast the Standard Boss Lure
Equip the $280 boss lure and fish up the Blue Shark so it surfaces to fight.
Watch your footing
The island is packed with coconut trees that block your dodges, so keep clear lanes to move through instead of getting boxed in.
Unload on the shark
Keep firing with your maxed Uzi or equivalent, using the trees for free damage only if the shark happens to snag on one.
Carry it to the Grillmaster
Once the shark is dead, bring the body back to the Grillmaster to complete the quest.
Fighting around the coconut trees
The coconut trees are the whole terrain puzzle here. They cut both ways: they’ll block your dodges and get you cornered if you’re careless, but the shark also snags on them now and then, which hands you a window of free damage. The catch is that you can’t plan around that — the snag is luck, not a strategy.
So play the parts you control. Keep moving through open lanes, time your reloads for when you’ve got distance rather than mid-scramble, and treat any tree-stick as a bonus instead of the plan. Positioning and reload discipline win this fight far more reliably than the shark’s pathing does.
Using the grill after the fight
Once the Grillmaster accepts the shark, you can finally use his grill — and that’s the real reward. Cooking becomes a money multiplier: an item’s value climbs from 1x up to 1.5x over the flame, then collapses to 0 if you let it turn solid black. Press F to inspect an item and watch its value update live while it cooks, and pull it at 1.5x. The multiplier applies to guns and other items too, not just fish, so it’s worth cooking anything before you sell it.

Frequently Asked Questions
Can you sell the Blue Shark instead of turning it in?
You can, but it’s a bad trade. The Blue Shark only sells for $300, and selling it forfeits the Grillmaster quest — meaning you lose the grill, which becomes your main money multiplier for the rest of the game. Turn the shark in; the sale value is trivial next to what the grill earns you.
Is the Blue Shark the same as the Goblin Shark?
No. They share the same 100 health and 70.0 weight, but they’re different creatures with wildly different value — the Blue Shark sells for $300, while the Goblin Shark sells for $6,200 and is considered the most valuable fish to cook. Only the Blue Shark is what the Island 3 Grillmaster is after.
