Route answer
Explore the full shoreline, talk to every local quest giver, preserve unusual items, then prepare for Blue Shark · Pufferfish. Do not leave until the unlock or travel hand-in is complete and the host has saved.
Desert Island progression checklist
- Speak to the swimmer
- Finish the bait chain
- Stock ammunition
- Use terrain without cornering yourself
Named encounters
The route currently associates Blue Shark · Pufferfish with this island. The game does not publish a formal boss count, so optional encounters and multi-stage bosses are labeled rather than forced into a misleading number.
Before you sail away
- Complete every obvious local hand-in.
- Move quest objects out of the general sale pile.
- Restock ammunition and keep a backup weapon.
- Use Save, Main Menu or Quit after a major objective; Patch 1.0.6 clarified the save flow.
Next stop: Rocks Island. Its opening route assumes the current island’s travel objective is finished.
