Full route at a glance
Finish the story in this order: Lighthouse → Forest → Desert → Rocks → Volcano. On the first four islands, the reliable progression loop is to accept the local NPC task, obtain the encounter bait, defeat the main boss, return the important drop, and then follow the new Radar coordinates.
Stage-by-stage walkthrough
| Stage | Immediate objective | Completion condition | Where it sends you | Source |
|---|---|---|---|---|
| 1 — Lighthouse Island | Use the Empty Beer Can to summon Spider Crab, then return its meat to receive boat keys. | Starting island; no unlock required. | Forest Island appears as a green Radar marker. | |
| 2 — Forest Island | Collect three Leeches, use the Modified Leech to summon Giant Piranha, and return its Skeleton. | Follow the green Radar marker. | Desert Island appears as a yellow Radar marker. | |
| 3 — Desert Island | Give the Tourist an endangered creature, use the Carrot to summon Pufferfish, and return its Fin. | Follow the yellow Radar marker. | Rocks Island appears as a red Radar marker. | |
| 4 — Rocks Island | Catch Tuna with the Professional Boss Lure, place it on dry ground to summon Albatross, then return the Albatross Head. | Follow the red Radar marker. | Final coordinates lead to Volcano Island. | |
| 5 — Volcano Island | Complete the scientist's quest and prepare for the final boss. | Follow the pink Radar marker; this is the final island. | No later island is listed. |
Before you leave an island
- Confirm the NPC has accepted the required item or boss drop. 2. Confirm new coordinates or a Radar marker appeared. 3. Keep the quest item instead of selling it. 4. Restock before using a one-purpose boss bait. These checks follow the reported progression loop; inventory-loss and failed-bait recovery rules still need current-build testing.
