The Spider Crab boss in How to Fish acts as a significant gatekeeper, preventing you from acquiring the boat needed to reach the next island. Because this enemy is capable of dealing massive damage, preparation is essential to surviving the encounter.
Preparation: The Fully Upgraded Knife
While it is technically possible to fight the boss with fists or knuckledusters, these methods are inefficient and dangerous. The most effective strategy requires a fully upgraded knife:
- Purchase: Buy the knife for $45.
- Upgrade: Use an anvil to upgrade the knife three times. This requires an additional $78.
To fund these upgrades, use hot dog bait while fishing and sell the clams you catch to maximize your income.
Combat Strategy: How to Attack
Once your knife is ready, use an empty beer can as bait to reel in the Spider Crab. The boss's primary attack is a straight-line charge. Follow these steps to win:
- Dodge the Charge: When the crab initiates its straight-line charge, move out of its path immediately.
- Identify the Stun: Wait for stars to appear over the crab's head. This visual cue indicates the boss is stunned and vulnerable.
- Counter-Attack: Strike the crab with your knife as soon as you see the stars.
- Reset: As soon as the crab recovers and begins to turn, stop attacking and retreat to avoid being hit by its claws. Repeat this cycle until the crab is defeated.
Post-Battle Rewards
Upon defeat, the Spider Crab will explode. Collect the meat and the Spider Crab Shell. Present these items to the lighthouse keeper to receive the keys to his boat. Finally, ensure you purchase the radar tablet from the lighthouse keeper for $10 so you can navigate to the next destination.
