Albatross

Also known as: Giant Bird, Terrorizing Bird

The Island 4 boss: a bird-type creature summoned by placing a caught Tuna on the ground as bait. Its exact name is disputed across sources.

How to Find It

Summoned by catching Tuna (itself a boss/major catch, using a Professional Boss Lure) and placing it as bait, now corroborated by two independent fish-list sources in addition to the earlier guide-site walkthroughs.

Three independently-written guide sites agree a bird-type boss exists on island 4 and agree on the Tuna-bait trigger, but give three different names for it. "Albatross" is used here as the working name because it has the most source support (3 of 5 sources found so far, including Game8's and Destructoid's separate fish-list boss tables), not because it has been confirmed. This is explicitly NOT a resolution. See the conflict record below and the Verification Notice on this page.
