Last island quest step by step
The scientist in the yellow hazard suit runs the final quest.
- Buy the Assault Rifle kit at the military supplies: rifle, maximum bullet damage, Extended Mag and extra slots.
- Give the scientist any five creatures (or five Beers) for the Fish Bucket.
- Fish up the Bowhead Whale with the Fish Bucket and kill it.
- Carry the body up to the crater rim and throw it in.
- Kill the Mutated Bowhead Whale that bursts out.
- Give the Whale Fin to the scientist, take the military boat keys and choose "Get back to the mainland".
What to buy on the volcano island
Military supplies sell every lure (including the Scientific Lure at $500 and the Scientific Boss Lure at $5,800), every weapon up to the Assault Rifle ($20,000), sharpening to 15, bullet tiers to 12, a fourth extra slot and all attachments.
Short on money? Scientific Lure catches sell for $1,360 to $2,200 raw.
Bosses on the final island
Two story bosses in a row: the Bowhead Whale, then the Mutated Bowhead Whale that it turns into in the crater. The optional Goblin Shark (Scientific Boss Lure) is also here and is the best single sale in the game.
How to get to the volcano island
Island 5 unlocks when the person in the Rocks shop gives you the flash drive for the Albatross Head. The Volcano then appears as a magenta dot on the Radar.
Since patch 1.0.5 you cannot sail to it before that.
Can I cook on island 5?
Yes. Throw a catch into a lava stream and it cooks for the same 1.5x as a grill, which matters because the Scientific Lure catches here are the most valuable regular fish.
Creatures on the Volcano island
The Scientific Lure pool bites here (Blobfish, Tripod Fish, Oarfish, Stonefish, Anglerfish, Superdwarf Fish), plus the Goblin Shark and both whales.
| Bait | Price | |
|---|---|---|
| Scientific Lure 21.7% | $1360 | |
| Scientific Lure 13.0% | $1400 | |
| Scientific Lure 13.0% | $1450 | |
| Scientific Lure 21.7% | $1500 | |
| Scientific Lure 21.7% | $1500 | |
| Scientific Lure 8.7% | $2200 | |
| Scientific Boss Lure 100% | $6200 | |
| Fish Bucket 100% ( from the Whale NPC ) | $8000 | |
| Not hooked by bait: a dead Bowhead Whale thrown in the volcano | Not sold whole: the 1.1.3 Fishipedia shows no price (-) for this boss; the fight drops a quest item and meat chunks instead (game data lists a nominal $15000 that players never receive). |
What to do after the last island
After the credits you wake up on Island 1 with your boat and every island still open, so you can keep going for collections and achievements.
Plan Handyman, the bare-hands final kill, before your final fight if you want it on the same run.
