How to Fish Boss Guides: Pufferfish, Shark, and More

How to Fish hides its difficulty behind ten boss creatures, and almost every one is summoned with a specific bait rather than found in the wild. This section covers the fights players actually get stuck on. The universal rules first: every boss has a white escape bar under its health that ends the fight if it empties, and every boss drops a named trophy that must be handed to an NPC to unlock the next destination.

The guides

The Pufferfish guide covers the game's biggest difficulty spike — the Carrot bait chain, the rolling charges, and the poison phase on the Desert island. The shark guide explains the $280 Standard Boss Lure, the Blue Shark fight, and the grill unlock that becomes your main money multiplier. For the full boss bait table across all ten creatures and the wider island route, see the all fish guide and the islands guide.
