Choose the guide for the boss you are currently facing, then compare its reported tactics with your in-game objective and interface. This hub covers only the two focused boss guides below.
Steam describes boss fights as part of the route to new islands. Detailed encounter tactics currently come from player reports rather than a developer strategy guide, so launch-period advice can change with later game updates.

Piranha Boss
The focused piranha page covers preparation, cautious movement around smaller enemies, a reported quest-drop precaution, and what to do after an unsuccessful attempt.
Pufferfish Boss
The focused pufferfish page covers preparation, spacing around terrain, and the limits of solo and co-op reports.

Community guidance: This page summarizes currently available player findings and has not been independently reproduced by our editorial team. Game updates may change quests, item requirements, spawn behavior, balance, or achievement conditions. Follow the current in-game objective and interface when they differ from this guide.
How to use launch-period tactics
- Treat movement paths, weapon mentions, and terrain behavior as reports from a particular build, not permanent mechanics.
- Follow the current objective if it differs from a guide's reported quest hand-in.
- Reassess a tactic after an update instead of assuming a previously reported safe position still behaves the same way.
