Evidence boundary for Tuna

The supported record identifies Tuna as a rare mini-boss associated with Rocks (Island 4). KeenGamer complete walkthrough & all fish locations (per-island bait tables), checked 2026-08-26.

Exact spawn odds, health, damage, sale value and map coordinates are deliberately omitted unless a stable source verifies them. A missed encounter is not proof of a hidden timer or a bug; confirm the listed lure and story access before changing anything risky.

Locations

  • Rocks (Island 4)

    The fourth island. Ten regular catches on the Professional Lure, the Tuna mini-boss, and the Albatross — the game's only aerial boss — drawn down by the Tuna's body.

What to do next

  • Check the Rocks (Island 4) route and unlock steps before treating a missing encounter as a defect.
  • Compare its bait and story order on the boss guide.
  • If the expected result still fails, keep the save intact and record the game patch, island, lure, solo/co-op role and exact completed action.
