How to unlock Forest Island

Return Spider Crab's shell, receive the boat route and follow the green Radar marker northwest.

If the marker is missing, return to Lighthouseand verify its named boss result was handed to the correct quest giver.

Forest Island walkthrough

  1. Use the free fish pool and Beginner Lures to fund reliable weapons and supplies.
  2. Locate all three ground Leeches around the Forest route.
  3. Trade the set to the lady by the lake for Leech Bait.
  4. Catch and defeat Giant Piranha, then return its trophy to reveal Desert Island.

Stage tips

  • The objective is three Leeches, not five; stale launch snippets reported the wrong count.
  • Save Beginner Boss Lures for Sunfish and The Old Pike when completing Collector.
  • Keep moving laterally during Giant Piranha and focus the boss instead of every add.
