01How to reach the second island
A published progression walkthrough places Island 2 after the Lighthouse Keeper’s Spider Crab route. Complete that quest to receive the boat keys, then buy the Radar and follow the next coordinates. This is a quest gate, not a shop shortcut or a cash total to grind toward.
The same community route describes every island as a sequence of NPC request, trigger, boss or task, then hand-in. Use the destination supplied by the completed quest instead of treating the map as a list of permanently fixed coordinates. The page therefore explains the documented story route without inventing a universal marker position.
02Recognize the three-leech blocker
This second-island task requires three leeches. They are small items found on the ground rather than fish caught from the water. Lower the camera and search around the active quest area, paths, vegetation and structures before assuming the shoreline is the right place.
This is a common mistake because the game title encourages players to search the water first. The direct answer is simple: this particular quest item is a ground pickup. The detailed leech page explains the evidence boundary and what to do if fewer than three appear.
03Protect quest items before clearing inventory
The second island adds more reasons to distinguish ordinary sale items from objects that advance a task. Read the objective before selling unusual catches, and avoid treating every creature part as ordinary meat. A visually distinct item can be the part that unlocks the next step.
The material does not provide a complete inventory catalogue for this island. It therefore cannot support a list of exact item labels, prices or all quest givers. The safer rule is to hold an unusual item until its nearby hand-in has been tested or its purpose is clear.
04Use money to solve a visible bottleneck
Catching and selling still funds the route, but buying something is not automatically progress. Spend when it answers a visible problem such as difficult combat, inconvenient travel or limited flexibility. A broad shopping spree can leave the crew underprepared when the current objective calls for a focused action.
The material names weapons, attachments and boat upgrades as systems, but it does not establish a complete second-island purchase order. This page does not turn those mentions into a tier list. Keep a cash buffer and choose the next tool only after identifying what is slowing the current objective.
05Keep uncertainty visible
The collected reports describe launch-day progress blockers, including missing leech spawns and unstable behavior. A player who has searched the likely ground areas once should not assume that the missing item is secretly underwater. Record the state of the quest and protect important inventory before repeatedly forcing the same attempt.
This page will remain cautious until repeatable released-build evidence fills the missing route details. It does not name unsupported NPCs, give a precise respawn timer or promise a fix. That boundary is intentional: an honest incomplete answer is safer than a polished but fabricated walkthrough.
