Route answer
Required item chain: A catch explicitly marked Endangered Species and the resulting Carrot. Target: Pufferfish. Finish the hand-in to reach Rocks route progression.
Step-by-step route
- Speak to the swimmer in yellow floaties.
- Check catches for the Endangered Species marker requested by the active objective.
- Exchange the qualifying catch for the boss-bait item.
- Prepare automatic fire and trigger Pufferfish.
- Keep the body part or trophy until the quest giver accepts it.
Do not lose the hand-in
Physics piles, the sale counter and co-op inventory confusion can all destroy a clean quest run. Name one item carrier, store important bodies away from ordinary fish, and use Save/Main Menu/Quit after a confirmed hand-in.
Verification note: Community sources disagree on a few lure and trophy names. This page uses paired terms rather than pretending one unverified label is official.
