The Pufferfish looks chaotic the first time you hook it. It isn't.

The fight rewards positioning over raw damage. We're not trying to out-shoot the boss in open water — we're forcing it into terrain, letting it grow, and turning its own size against it.

By the end of this guide, you'll know what to fish up beforehand, which gear actually matters, where to stand, how to survive the poison trail, and what the trophy looks like once the boss is dead.

↖ Before the Fight: Bait and Gear

Most failed attempts start before the fight even begins. Wrong catch, wrong loadout, wasted cash on upgrades that don't move the needle.

↖ Catch the Right Fish

To unlock the Pufferfish encounter, catch one of these using standard lures:

• Needlefish
• Bowl Fish
• Seahorse

Here's the catch: drip-style creatures don't count. They look rare. They're the wrong item for this quest line.

Turn in a correct catch and you'll receive a carrot, which opens the combat prep phase.

↖ Gear Setup That Actually Wins

The SMG is the right call here. Steady fire, fast tracking, and enough pressure to grow the boss quickly — that's what this fight demands.

Takeaway: you're building for control, not precision. The boss is big and constantly moving — your job is landing shots while staying alive.

↖ The Rock-and-Tree Trap

The safest method uses two rocks and two trees to build a natural choke point. Lure the Pufferfish in, let it get stuck, and farm free damage.

↖ Why This Setup Works

Why does trapping it even matter? Because early on, the Pufferfish is small enough to squeeze through gaps you can't block. Every hit you land makes it bigger — and bigger means it can't fit anymore.

What starts as a messy chase turns into a shooting gallery.

The first half teaches the boss where to go. The second half punishes you for following too tight.

↖ Drill the Loop First

Run the circle before the boss ever spawns. Seriously — this rehearsal saves runs.

1. Circle the rock without clipping it.

2. Cut around the tree without losing speed.

3. Widen the loop enough to dodge poison later.

4. Turn back on the boss without walking into its path.

5. Fire while moving — never while standing still.

If you can run this loop clean before the chase starts, you won't panic once it does.

↖ Starting the Fight Without Getting Wrecked

The opening seconds are the messiest part. The boss is still small and fast enough to slip the trap entirely.

↖ Throw It Away From You

When you reel in the Pufferfish, throw it away from your character, not right beside you.

Those extra seconds buy you room to:

• Sprint toward the trap.
• Create distance before the chase starts.
• Dodge early contact damage.
• Start from control instead of scrambling.

If it spawns close and pressures you instantly, don't greed for damage. Run first. Reset the angle. Shoot once it's chasing through the route.

↖ Force the Jam

Guide it toward the gap between rock and tree. Early on, it'll wiggle through — that's normal, it's still small.

1. Run to the rock.

2. Let it chase you into the terrain.

3. Cut around the tree.

4. Turn and fire short bursts.

5. Keep moving before it closes the gap.

6. Repeat until it's too big to squeeze through.

Once it jams, unload with the SMG. This is where max bullet upgrades pay off — more ammo, more uptime, fewer interruptions.

↖ Phase One: Full to Half Health

This phase is about forcing growth. More damage equals a bigger boss equals a tighter trap.

↖ Don't Overcommit Early

The biggest mistake here: standing still too soon. You see it hesitate near the rock, assume it's stuck, open fire — then it slips free and runs you down.

Use measured aggression instead:

• Fire only when it's visibly blocked.
• Stop the moment it starts squeezing free.
• Move before it reaches the corner.
• Keep the loop tight enough to hold control.
• Don't run so far the boss resets its path entirely.

You're not speedrunning the first twenty seconds. You're building the trap. Once it grows, the damage windows get much safer.

↖ Fire the SMG With Intent

The SMG lets you hold pressure while adjusting aim — that doesn't mean spraying into empty space.

• Close range: steady bursts into the body.
• When it turns: track and keep moving.
• When it slips free: stop shooting, reposition.
• When it's stuck: dump sustained fire until it moves again.

The compensator cuts recoil on those long bursts. The laser sight keeps close-range shots consistent through the chaos.

↖ Phase Two: Surviving the Poison Trail

At half health, the fight changes. The Pufferfish starts leaving a poison trail — and stepping into it can kill careless players fast.

The trap still works. Your movement just has to get cleaner.

↖ Widen the Circle

In phase one, a tight loop is fine — the only threat is the boss body. In phase two, the trail is just as dangerous as the boss itself.

If you keep running the same tight loop, you will eventually step into old poison. That's how clean runs fall apart.

1. Run wider around the trees.

2. Avoid cutting directly behind the boss.

3. Let old trails fade before crossing them.

4. Use the outer edge of the terrain loop.

5. Fire only from a safe angle.

The first moments after half health are the most dangerous — the boss may still fit through gaps. Keep damaging it and it grows back into the trap.

↖ Respect the Trail, Not the Boss

Here's the catch: once it's big, its movement barely threatens you — terrain does the blocking. The trail punishes autopilot.

If you're dying after half health, the problem usually isn't your damage. It's your pathing.

Phase two rewards discipline. Same strategy — just no greedy shortcuts through poison.

↖ Full Fight Walkthrough

1. Buy standard lures and fish until you land a Needlefish, Bowl Fish, or Seahorse.

2. Skip drip-style creatures — they don't count.

3. Turn in the fish and receive the carrot.

4. Equip the SMG. Sustained damage over slow precision.

5. Buy the compensator for recoil control.

6. Skip the red dot. Iron sight is enough.

7. Buy the laser sight for close-range tracking.

8. Max the bullet upgrades.

9. Locate the two rocks and two trees.

10. Drill the loop before the boss spawns.

11. Catch the Pufferfish and throw it away from your body.

12. Sprint to the rock — don't fight in the open.

13. Drag it into the choke point.

14. Fire when it's stuck. Bigger boss, bigger openings.

15. Widen the loop at half health.

16. Fire only from safe angles. Don't greed through poison.

17. Check the drops carefully — the trophy is easy to miss.

↖ Finding the Trophy

The boss drops a pile of meat when it dies. That's not the item you need.

The Pufferfish trophy looks like the bottom part of the tail — small, easy to walk right past.

• Check the ground carefully.
• Don't grab meat and bail immediately.
• Look for the tail-bottom piece specifically.
• Pick it up before returning to the NPC.

Hand it over and the next island unlocks.

↖ Mistakes That Get Players Killed

Fighting in the open. No terrain means you're running the whole fight instead of dealing controlled damage. Use the rock-and-tree trap every time.

Shooting too early. Firing before the boss is stuck just gives it time to reach you. Burst-fire until it's genuinely jammed.

Ignoring the poison trail. It's the real second-phase killer. Widen your circle and stop crossing directly behind the boss.

Missing the trophy. It's small and doesn't stand out. Search the drops before you leave the arena.

↖ FAQ

What fish do we need before fighting the Pufferfish boss?

Catch a Needlefish, Bowl Fish, or Seahorse with standard lures. Drip-style creatures don't count, no matter how rare they look.

What's the best weapon for the Pufferfish boss?

The SMG. Pair it with a compensator, laser sight, and max bullet upgrades for sustained pressure through the trap phase.

Why does the Pufferfish get easier as the fight goes on?

Damage makes it grow. A bigger boss can't slip through the rock-and-tree gap, which hands you safer damage windows.

How do we survive the poison trail phase?

Widen your loop at half health. Never follow directly behind the boss, and never cut through poison just to squeeze in extra shots.

↖ The Bottom Line

This isn't a damage race — it's a positioning puzzle with teeth. Catch the right fish, gear the SMG properly, and let the rocks and trees do the dirty work while the boss grows into its own trap.

Once the poison trail shows up, widen the loop, stay patient, and only fire when the angle is clean. Play it like a controlled hunt, grab the tail-bottom trophy, and move on to the next island.
