This guide separates the route item from the combat plan so you can prepare before spending a lure, placing a body or consuming a unique quest trigger.

How to trigger Tuna

1,200-coin Professional Boss Lure (dedicated story encounter).

Reach Rocks Island by following the five-island story route. Return Pufferfish's fin and follow the red Radar marker.

Preparation checklist

  1. Farm Professional catches before buying the one-use boss lure.
  2. Clear a safe patch of grass where the body can be staged afterward.
  3. Make sure no one in co-op cooks or sells quest-critical catches by mistake.

Fight tactics

  1. Keep the fish in view during its leaps and fire during predictable landings.
  2. Avoid the death-and-spawn edge case fixed in Patch 1.0.10 by fighting with a stocked health reserve.
  3. Place the defeated body on land only when ready for Albatross.
Common pitfall

The defeated Tuna is the next encounter trigger. Selling, cooking or gambling the body breaks the intended Albatross chain.

Reward and what to do next

The defeated Tuna body, which is the Albatross trigger.

Put trophies and physical trigger bodies into a deliberate safe place before shopping or sailing. Patch 1.0.10 improves ground-item persistence, but inventory remains the safest place for portable quest results.
