Island unlock order

You generally cannot skip islands. The next Radar marker appears after a boss drop is handed to the quest NPC — not after a money or catch threshold.

The chain (you cannot jump)

1. 1 · Starter / lighthouse

   Learn cast–sell, first gear, boat, Radar. Leave only when the local quest / Radar works.

2. 2 · Forest

   3 ground leeches → Modified Leech → Giant Piranha → skeleton hand-in → Island 3 coordinates.

3. 3 · Desert

   Same rule as forest: kill the quest target, pick the distinctive drop, hand it in. Do not sell the trophy.

4. 4 · Rocks

   Later combat check. People search a pufferfish-style fight here; we have not locked the island in-game yet, so treat this as the later half of the chain, not a skip target.

5. 5 · Volcano / end islands

   Last bosses, then the route back toward the mainland. Still quest-gated.

Stuck with no new coordinates?

• You killed the boss but did not return the distinctive drop (skeleton / trophy), or you sold it.
• Radar disappeared after a reload: on the piranha island, check a spare radar leaning under the signposts.
• Farming the current island for cash is fine. It will not replace the hand-in.
