Pufferfish Boss Guide

What is officially confirmed about the Pufferfish?

Two hard facts, both from official sources:

• The Pufferfish is a boss in How to Fish, the 2026 physics fishing game by Dazed Games (Steam App 4001890).
• It was nerfed in patch 1.0.4 (August 22, 2026), alongside the Whale boss. The official notes are on the Steam news page, and our patch 1.0.4 summary lists every confirmed change.

That is the complete list of confirmed Pufferfish facts. Everything else on this page is clearly labeled as loop-level guidance or pending verification.

How does the boss progression loop work?

Bosses in How to Fish are not optional side fights — they gate island progression. The loop runs:

1. Quest — a quest line leads you toward the boss encounter.
2. Bait — you prepare what the encounter requires.
3. Boss — you fight and defeat the boss.
4. Trophy — the boss drops a trophy.
5. NPC — you turn the trophy in to the relevant NPC.
6. Next Island — the next island unlocks and the loop restarts.

The practical takeaway: if the Pufferfish fight feels out of reach, the answer is usually earlier in the loop — finish the current quests, make sure you have the required bait, and upgrade your gear with money from selling catches (see the money guide). The island progression guide maps the whole chain.

What are we still verifying?

Honesty is this site’s editorial policy, so here is exactly what is not confirmed yet:

• Exact stats — HP, damage values and phase structure have no official published numbers.
• Precise nerf details — patch 1.0.4 says the Pufferfish was nerfed, but the official notes do not publish per-stat before/after values.
• Strategy specifics — community-reported tactics are being collected and tested against the current patch before publication.

As each item is verified, this guide will be updated and stamped with the patch version it was checked against. Until then, treat any site quoting exact Pufferfish HP with suspicion.
