To beat the pufferfish boss solo in How to Fish, unlock the island boss bait from the tourist, bring cooked fish for healing, keep your distance while it rolls, and reposition aggressively when phase two adds the purple poison cloud.
Beat the pufferfish solo by staying mobile, healing immediately after every hit, and resetting your position whenever the phase-two poison cloud closes off your route. The pufferfish is one of the tougher solo walls in How to Fish, the physics-based fishing-and-shooting game from Dazed Games that launched on Steam on August 20, 2026. There is no second gun to draw its attention and no teammate to revive you, so the fight comes down to spacing, healing, and controlling the second phase. Follow this route to bring it down without a partner.
Boss health also scales with party size: each extra player adds a chunk of the boss’s base health. Most bosses use a 0.5 multiplier, but the pufferfish uses 0.3, so it is the one boss that does not get much tougher when friends join. More players still means more boss health as well as more guns, so a bigger party is not automatically easier.
| Boss | Solo | 2 players | 3 players | 4 players |
|---|---|---|---|---|
| Spider Crab | 750 | 1,125 | 1,500 | 1,875 |
| Giant Piranha | 2,500 | 3,750 | 5,000 | 6,250 |
| Pufferfish | 18,000 | 23,400 | 28,800 | 34,200 |
| Albatross | 7,800 | 11,700 | 15,600 | 19,500 |
| Mutated Bowhead Whale | 38,000 | 57,000 | 76,000 | 95,000 |
Finding the pufferfish and its carrot bait
The pufferfish is the Island 2 boss, and you cannot summon it until you have the bait it wants. The bait is a $100 carrot from the tourist on the island. Give him an endangered fish — a flagged species such as a needlefish, bowl fish, or sea horse, all caught with the pink standard lure — and he hands over the carrot.
Key Island boss lures like this one are never sold in shops. Every island produces its boss bait through a quest, so the carrot is the only key into this fight — there is no store shortcut. Once it is in your pockets, the pufferfish is ready whenever you are.
Gearing up before the pufferfish fight
Every heal and every dodge counts when you play solo, so preparation decides half the fight. Finish this setup before casting the carrot.
Cook a deep stock of fish
Hold fish over the grill and pull each one at the 1.5x value mark. A burnt, solid-black fish restores almost no health, so remove each fish before it overcooks.
Buy extra inventory and hotbar slots
Extra slots let you carry more cooked fish into the fight. Against late bosses, that reserve keeps you alive through a bad stretch.
Bring a strong, upgraded gun
Bring a well-upgraded weapon you can use reliably instead of an early-game piece. The pufferfish does not stun, so you need steady, reliable damage during each opening.
Do not lean on the coconut trees
The island is full of coconut trees, and they block your dodges as often as they help. Sidestep them as hazards instead of camping behind them as cover.
Fighting the pufferfish in phase one
Phase one is a kiting fight. The pufferfish rolls straight at you and grows larger as the battle continues, but it has no stun window to exploit. Later bosses do not freeze like the first island’s crab, so keep moving and chip away at its health between charges.
Never stop moving
Standing still lets the roll catch you. Keep circling so the pufferfish is always chasing you instead of landing on you.
Dodge the rolling charge
Read the wind-up, step off its line, and let the roll carry past you before shooting.
Shoot in the openings
Once the charge overshoots, pour damage into the pufferfish while it resets, then disengage before the next roll.
Eat cooked fish the instant you are hit
Heal immediately after taking damage. Waiting until your health is low leaves you one mistake away from dying.
Surviving phase two and the poison cloud
At half health, the pufferfish changes the entire arena by trailing a purple poison cloud. The cloud ends most solo runs when players back into the gas while concentrating on their aim. From this point onward, survival takes priority over squeezing out extra damage.
Watch for the half-health shift
The purple trail marks the start of phase two. Widen your spacing as soon as it appears.
Rotate away from the cloud
Circle toward open ground to keep the gas behind the boss and away from your feet.
Never reverse into the trail
Check your path before backing up. Retreating blindly into the cloud is the most common solo death in this fight.
Prioritize survival when the arena tightens
When the cloud and the boss crowd your space, give up the damage window, reset your position, and re-engage from clean ground instead of trading hits in the gas.
Carry far more cooked fish than you think you need — a deep healing reserve turns a losing solo pufferfish run into a winnable one.

Solo mistakes that end pufferfish runs
Most failed solo attempts come from a few avoidable errors that compound quickly without a teammate to rescue you. The biggest mistake is starting without a stack of cooked fish. With no healing, one roll or brief contact with the poison can snowball into a wipe.
The island terrain is the next trap. Coconut trees pin you in place mid-dodge, and getting stuck against one during a roll or while the poison cloud closes in can end a run you were winning. Keep the fight on open ground.
Respect phase two. Running through the poison cloud to chase damage or rushing the boss as soon as it changes will dismantle an otherwise controlled fight. When the purple trail appears, slow down, re-establish your distance, and deal damage on your terms.

Frequently Asked Questions
Can you beat the pufferfish boss solo?
Yes. The fight is harder alone because no one can revive you or split the boss’s attention, but it is fully solo-clearable. Keep moving, heal with cooked fish, and stay out of the phase-two cloud. Weapon upgrades also cost less on a solo save, so gearing up is not as steep as it sounds.
What does the pufferfish boss drop?
It drops the Pufferfish Fin, its distinct trophy item. Every boss in the game leaves a specific item like this instead of plain meat, making each one worth farming. The pufferfish itself can also be sold for $12,000 if you would rather bank the payout.
