🗺️ Islands

Islands

All five islands — shops, quests and unlock conditions.

Core Unlock Rule

Take a quest from the island NPC, then gather items to obtain the boss bait and lure out the boss.
Beat the boss and pick up its named drop — the trophy is the real proof of progress.
Hand the trophy back to the same NPC who gave you the quest to reveal the next island on the radar.
Coordinates only appear after the hand-in, not after the kill itself.

Quest · Who Stole My Beer?

Earn cash, buy the Beer Can and feed it to the Lighthouse Keeper; he returns the empty can.
Use the empty can to lure out the Spider Crab boss.
Bait its charge, sidestep, and hit it while stunned; defeat the Spider Crab.
Pick up the trophy and hand it to the Keeper to get the Boat Keys.

Unlocks: Forest island — green dot, northwest of the Lighthouse

Buy the radar ($10) before leaving; this fight needs no rod upgrades or harpoon — just the empty can.

Quest

Pick up 3 leeches from the ground (physical ground pickups, not fished).
Hand them to the lady by the lake to get a modified leech lure.
Cast it to start the Giant Piranha boss fight; it brings minions, so clear them first.
Beat it, pick up the skeleton, and return it to the lady for the Desert coordinates.

Unlocks: Desert island — yellow dot, to the west

The whole team should bring a Pistol or Shotgun with a laser sight and damage upgrades for close-range hip-fire.

Sight UpgradesCompensatorMag UpgradesBig Motor UpgradeBoat Radar Upgrade

Quest

Find the tourist sitting under a tree who is scared of the water and a specific fish.
Catch a Needlefish (or a Seahorse / Bowlfish) and hand it over to get a Carrot.
Use the Carrot as bait to summon the Pufferfish boss (it rolls at you like a wrecking ball).
Beat it, pick up the fin, and hand it to that same tourist for the Rocks coordinates.

Unlocks: Rocks island — red dot, further west

The Pufferfish grows larger, with stronger and wider charges, as its health drops; kite around trees and use trunks to block its charges. Handing the fin to the wrong NPC halts progress.

Quest

Talk to the NPC in the shop, who warns you about a large bird.
Buy the Professional Boss Lure and hook a single Tuna; dodge its jump and finish it with the Shotgun.
Lay the dead Tuna on the ground and wait a few seconds for the Albatross to arrive.
The Albatross fights at long range — bring the SMG or Sniper Rifle (not the Shotgun) and stay under cover from its attacks.
Beat it, pick up the Albatross head, and hand it to the shop NPC for the Volcano coordinates.

Unlocks: Volcano — pink dot, directly north

Buy the boat radar upgrade before sailing here so the radar mounts on the deck.

Physically throw the Bowhead Whale into the volcano crater to trigger the mutated final boss.
Beat the final boss to unlock the route back to the mainland and finish the story.

Unlocks: Route back to the mainland — story complete

After the credits you wake back at the start with endgame gear and free movement between all five islands for collection cleanup.
