How to Fish Game bosses and island progression

🦀 Lighthouse — Empty Beer Can and Spider Crab

The opening boss is tied to the Lighthouse Keeper's stolen-beer quest:

• Give the Keeper a Beer and equip the returned Empty Beer Can as bait.
• Hook the Spider Crab, sidestep its charge, and attack from behind during its stun window.
• Return the named crab drop to the Keeper for the Boat Keys, then check the Radar.

🪱 Island 2 — Three Leeches and Giant Piranha

The forest lady's request produces the only bait that advances this island.

• Pick up three Leeches from the grass and complete the 3/3 counter.
• Return to the quest giver for Father's Favorite Bait, commonly described as Leech Bait.
• Use it to hook the Giant Piranha, defeat the boss, and return its story drop for the next coordinates.

🐡 Island 3 — Tourist, Carrot, and Pufferfish

Complete the Tourist's endangered-creature request before looking for the boss:

• Catch a valid endangered creature and give it to the Tourist to receive the Carrot.
• Cast with the Carrot to summon the Pufferfish. Circle solid cover, avoid its rolls, and stay out of the purple poison trail during phase two.
• Return the Pufferfish Tail to the Tourist for Island 4 coordinates.

🦅 Island 4 — Tuna and Terrorizing Bird

This stage uses a mini-boss as bait for the island's main encounter.

• Use the Professional Boss Lure to catch a Tuna.
• Place the Tuna on the ground to draw in the Terrorizing Bird.
• Use a building or other solid cover against its dives and ranged attack, then return the Bird Head for the late-game route.

🐋 Volcano Route — Bowhead Whale and Final Boss

The military and scientist quests lead into the final sequence:

• Complete the scientist's requests and obtain the whale bait or container named by the current objective.
• Catch the required Bowhead Whale, keep its body, and carry it to the volcano.
• Throwing the Whale into the crater triggers the Mutated Bowhead Whale fight.
• Return the final Tail to the scientist, take the RHIB Keys, and start the RHIB to reach the credits.
