How do you summon the first boss (Spider Crab) in How to Fish?

To summon the Spider Crab on Island 1, purchase a $12 Beer Can from the Lighthouse general store. Drink the beer with Old Pete at the campfire to empty it, attach the Empty Beer Can to your fishing line as bait, and cast into the deep coastal waters off Lighthouse Beach.

Why should you never sell boss trophies in How to Fish?

Boss trophies (Spider Crab Shell, Pike Sawjaw, Inflated Poison Sac, Albatross Crown Feather) are non-renewable quest items required by NPCs to repair your boat and clear nautical barrier storms to unlock the next island. Selling them to a vendor permanently locks your progression on that save file.

What is the best weapon loadout for boss fights in How to Fish?

The universal meta for boss battles is the Pull Back Fishing Rod ($250) to endure infinite line tension while hooking the boss, paired with the Submachine Gun (SMG, $450) or Lever-Action Rifle to deal rapid airborne bullet damage and sustain trickshot multipliers.
