How to Fish

Corroborated

Confirmed by multiple independent player-written sources, not yet by an official source or in-game evidence.

Rarity
Boss-tier
Value
2000
Best Method
Caught with a Professional Boss Lure using the Fishing Rod.
Requirements
Used as bait to summon the Island 4 boss (Albatross) once caught.

Two independently-written sources (Game8, Destructoid) reference Tuna in this dual role, a valuable catch AND a boss-summon item, which is why it clears the two-source bar for corroborated status. Also separately listed as its own boss entity (`bosses/tuna`) given its role gating the Albatross fight.
