Rocks (Island 4)
The fourth island. Ten regular catches on the Professional Lure, the Tuna mini-boss, and the Albatross — the game's only aerial boss — drawn down by the Tuna's body.
How to unlock
Hand the Pufferfish trophy to the Desert NPC for the coordinates.
⚠️ Avoid these mistakes on Rocks (Island 4)
- Never sell or cook the Tuna — its body is the only Albatross bait, and a replacement costs another $1,200 Professional Boss Lure.
- Bring a long-range weapon for the Albatross (sniper rifle recorded at $3,800 plus scope); arriving with short-range guns turns the only aerial fight into a slog.
- Verify the Volcano coordinates actually appeared after the head hand-in before sailing away.
Catch the Rocks pool with the Professional Lure
- All ten normal catches use the Professional Lure: Sengarat, Red Snapper, Tigerfish, Parrotfish, Bass, Halibut, Flying Fish, Eel, Voxel Fish, and Dripper.
- Arriving with an older lure tier wastes your time — upgrade before you farm.
Tuna mini-boss and the Albatross: the game's only aerial fight
- Buy the Professional Boss Lure on the Rocks island ($1,200 per community price tables).
- Cast to summon the Tuna, dodge its leaping attacks, and defeat it.
- Do not sell the Tuna — its body is the bait for the Albatross.
- Drop the Tuna on the grass and wait for the Albatross to fly down and take it.
- Bring a long-range weapon: one field guide records the Island 4 sniper rifle at $3,800 plus a separately bought scope.
- Defeat the Albatross and hand its head to the NPC for the final island (Volcano) coordinates.

Collection & drip variants on this island
Every normal creature on Rocks (Island 4) (Sengarat, Red Snapper, Tigerfish, Parrotfish, Bass, Halibut, Flying Fish, Eel, Voxel Fish, Dripper, Tuna, Albatross) has a rare drip variant with a rainbow-colored name. Drip variants appear in the same pool, on the same bait — there is no special drip lure. Kill the drip creature so the entry registers, then press Tab in-game to check the encyclopedia. Track what you still need with our collection tracker — normal catches count toward Collector, drip variants toward Fishipedia.

Island not unlocking?
Progression gates in How to Fish are quest hand-ins, not discoveries: Rocks (Island 4) unlocks when the previous island's boss trophy is delivered to its quest NPC. If the next destination has not appeared, return to the previous island, confirm the boss was defeated and the trophy actually handed in, then restart the game once. Still stuck? Check the troubleshooting hub for save, quest-state, and multiplayer-desync checks.
Frequently asked questions
How do I catch the Albatross in How to Fish?
You cannot hook it with a rod. Defeat the Tuna (Professional Boss Lure, $1,200), drop the Tuna's body on the grass, and wait for the Albatross to fly down to take it. Bring a long-range weapon — one field guide records the Island 4 sniper rifle at $3,800 plus a separately bought scope.
Can I sell the Tuna after killing it?
Only if you skip the Albatross — its body is the bait. Selling it means buying another Professional Boss Lure and re-farming the fight, so keep it on the ground instead.
How do I unlock the final island in How to Fish?
Defeat the Albatross on the Rocks island and hand its head to the NPC. He gives you the coordinates for the Volcano, the fifth and final island.
