Unlock the encounter
Speak with the woman in the forest area of Island 2. Her dinner quest is the route forward. Search the tall grass for three leeches; the pickup prompt is often easier to notice than the small model on the ground.
Hand in all three leeches to receive Leech Bait. The bait is for the story boss and is consumed by the attempt, so finish shopping and healing before attaching it to the rod.
Preparation checklist
Island 2 sells the Pistol, Shotgun, ammunition upgrades, and Dynamite. A fully upgraded ranged option is more valuable than carrying several weak weapons. The Pistol keeps damage on the large target; the Shotgun's spread is useful when small piranhas close the gap.
Cooked fish is your margin for error. Keep several catches in easy hotbar slots so you can heal without opening the inventory while the pack is moving toward you.
- Upgrade ammunition to the Island 2 cap if money allows.
- Carry a Pistol for the boss and a Shotgun or melee weapon for nearby adds.
- Place explosives before the pull only if you can shoot them from a safe distance.
- Leave a clear running loop around the island instead of fighting beside trees and props.
Solo strategy
Start sprinting as soon as the Giant Piranha reaches land. The boss is manageable alone at first, but smaller piranhas join after it takes damage. Keep the whole group behind you, turn only for controlled shots, and resume moving before they surround you.
Aim the Pistol at the boss when the path is clear. Switch to the Shotgun only when several small piranhas are close enough for the wider spread to matter. Killing the boss does not automatically remove every add, so preserve health and ammunition for cleanup.
Dynamite can deal a strong opening burst, but it also kills careless players. Treat it as a prepared trap, not something to throw at your feet during the pack phase.
Co-op strategy
Boss health scales with more players, but co-op gives the group cleaner roles. One player keeps the Giant Piranha moving in a predictable circle while the others maintain headshots and call out smaller fish approaching from the side.
Some groups use the boat to create a wider turning circle around the island. This is effective only when the driver can hold a stable path and the shooters can keep line of sight. A disorganized boat attempt usually costs more time than a simple land kite.
Finish the Island 2 quest
Collect the progression drop after the boss dies and take it back to the woman. Completing the hand-in advances her dinner quest and adds the next island coordinates to the radar.
If Island 3 does not appear, verify that the item was returned to the quest giver. Defeating the boss alone is not the final trigger.
