BOSS / YELLOW ISLAND

How to beat Pufferfish

The Pufferfish fight is a spacing check. Bring the right bait, use the arena's trees to break pressure, and stop chasing through the purple poison trail.

Community-tested planRoute boundary: v1.0.6Updated 25 Aug 2026
Quick answer: use the carrot to start the encounter, bring an SMG with magazine and recoil help, open with dynamite when the boss is committed, then circle the trees and fire from safe angles. Avoid the purple trail. After the kill, take the fin back to the tourist to unlock the Red island route.

Before the fight

ChecklistWhat to do
TriggerBring the carrot bait and use it for the Pufferfish encounter.
WeaponUse the SMG as the practical baseline; magazine and recoil help reduce exposed reloads and missed shots.
BurstKeep dynamite available for a clean opening rather than throwing it while the target is moving unpredictably.
ArenaIdentify the trees before committing. They are spacing tools, not just decoration.
ExitLeave with the Pufferfish fin and deliver it to the tourist.

Fight plan

  1. Start on the edge of the arena. Give yourself room to see the boss path and keep a tree between you and a bad approach.
  2. Take the first clean burst. If the Pufferfish commits to a predictable line, use dynamite and follow with SMG fire. Do not stand still to force every shot.
  3. Circle, do not corner yourself. Move around the trees in a wide loop. The goal is to keep an exit lane open when the boss changes direction.
  4. Respect the purple poison trail. Treat the trail as a temporary no-go zone. Cutting across it for one extra burst usually costs more health than it saves.
  5. Reload behind space. Break line of approach with terrain, reload, then re-enter on the next safe window.
  6. Pick up the fin and complete the handoff. The boss kill advances the route only after the required item reaches the tourist.

Why the fight goes wrong

ProblemCorrection
Running in a straight lineUse a wide circle around the trees so the boss cannot close the same angle every time.
Chasing through poisonWait for the trail to clear and re-enter from a safe side.
Reloading in the openUse terrain to create a reload window; magazine help is valuable because it reduces how often this happens.
Leaving without the finCheck the pickup and inventory before sailing away, then visit the tourist.

After Pufferfish

Return the fin to the tourist to receive the next route information and continue toward Red island. If the route does not update, check the NPC handoff first; do not assume the radar or save is broken until the quest state has been verified.
