In Dazed Games’ Steam game How to Fish, the Professional Boss Lure is bought on Island 4 for $1,200, and you use it to fish up the tuna mini-boss that starts the seagull boss fight.
How to Fish is the physics-based co-op fishing game from Dazed Games that launched on Steam on August 20, 2026, and despite the name it’s every bit a shooter once the bosses show up. The Professional Boss Lure is one of those late-game shop items, and it exists for a single job: it’s the key to the Terrorizing bird quest, the seagull boss on Island 4. If you’re trying to buy it, here’s exactly where it lives and what it costs.
Where to buy the Professional Boss Lure
| Detail | Answer |
|---|---|
| Island | Island 4 |
| Price | $1,200 |
| Lure type | Mini-boss lure (shop-bought) |
| Main use | Fish up the tuna mini-boss |
| Boss chain | Terrorizing bird (seagull boss) |
| Item | What it is |
|---|---|
| Professional Boss Lure ($1,200) | Island 4 mini-boss lure that summons the tuna |
| Professional / Orange lure ($50) | Standard farming lure for ordinary fish |
The Professional Boss Lure is sold on Island 4 for $1,200. That price is from a multiplayer run, and lures cost the same whether you’re solo or in co-op. The island’s shops carry it alongside the other Island 4 gear, so you buy it there rather than earning it from a quest.
One thing worth pinning down before you spend: this is not the cheap orange lure you were farming with earlier. The similarly named Professional (Orange) lure is a $50 standard farming lure for pulling up ordinary fish. The Professional Boss Lure is a separate, far pricier item whose only purpose is summoning a mini-boss.
When the Professional Boss Lure matters
Key This lure only becomes relevant once you reach Island 4 and pick up the Terrorizing bird quest, where the islanders need you to deal with a seagull boss. The lure is the front end of that whole chain: no lure, no tuna, no seagull fight.
It helps to know how the game splits its lures. Mini-boss lures like this one are bought in shops, so a big price tag is normal for them. The bigger island boss lures can’t be bought at all — every island hands you one through a quest instead. So if you’re hunting for the tuna’s summon, the shop is the right place to look.
Using the lure to start the seagull fight
Buy the Professional Boss Lure
Pick it up on Island 4 for $1,200 before starting the Terrorizing bird quest.
Fish up the tuna
Use the lure to summon and reel in the tuna, which is a mini-boss in its own right.
Kill the tuna
Take down the tuna mini-boss once it’s out of the water.
Drop the tuna as bait
Set the tuna on the ground so it acts as bait for the seagull.
Let the seagull take it
The seagull comes down for the tuna, and that triggers the boss fight.
Keep in mind the tuna is always consumed in this process — it’s spent as bait every time, so plan on it being gone once the fight begins.
Whether the lure survives a use
Regular lures and mini-boss lures can break on use and vanish in a puff of smoke, so there’s never a guarantee you get one back. The Professional Boss Lure has a durability roll, which means it may survive a summon and be reusable — but don’t count on it. If you expect to retry the seagull fight a few times, budget for the possibility of buying another.
Prepping for the seagull boss
The seagull fight rewards positioning more than raw aim. Use the island’s buildings as cover to break line of sight, and the casino is the strongest spot for visibility while you’re sheltering. Every enemy shows a red dot through walls and terrain, so you can track the bird from cover and only step out when it’s safe to shoot.
Bring a strong, upgraded weapon into it — a maxed Uzi handles the job well, and if the recoil is fighting you, an upgraded sniper rifle is the alternative worth building instead.
Buy the lure and a backup in the same trip. The tuna is always consumed and the lure can break on use, so carrying a spare saves a second shopping run if your first seagull attempt goes wrong.
