How to Kill Sunfish in How to Fish

The Sunfish appears in the latest AllThings.How lure table (2026-08-26) as an Island 2 / Forest boss caught with the Beginner Boss Lure on the regular Fishing Rod, but it has no dedicated section in publicly available boss guides — its personal attack patterns are not separately documented in the source material.

Like every boss, it is bound by the white patience bar under the health bar: wasted time or bad distance makes it flee, and the lure is consumed on a failed attempt.

The Sunfish is an Island 2 side boss caught with the Beginner Boss Lure — one of the earliest fights you can attempt.

• Complete the local Island 2 NPC tasks and buy the Beginner Boss Lure.
• Eat to full health, bait up, cast the rod, and let the boss come to you.

• Avoid the telegraphed attack, deal damage during the hard-hit window, and never let the white patience bar run dry.
• Keep the trophy after the kill — do not sell mission loot before checking what NPCs want.

💡 The general eat-first-then-cast rule covers the rest; this is a straightforward early-game fight.

Because the Sunfish is optional and shares its lure with The Old Pike, the failure patterns are all about preparation rather than the fight itself:

• Nothing took the bait: an earlier Island 2 NPC task is unfinished — the boss summon is gated behind the local chain, so talk to the NPCs and recast.
• The boss fled: the white patience bar ran out while it was unsupervised — stay engaged, keep output during the hard-hit windows, and remember the lure is consumed either way.
• Killed it, nothing unlocked: side bosses do not move the map; check whether an NPC wants the trophy before selling it.
• Same lure, different fish: the Beginner Boss Lure also pulls The Old Pike — if you get the Pike instead, that is the shared pool working as documented, not a bug.
