How to Get Leeches in How to Fish
Last verified August 29, 2026 · Game version 1.0.10
The short answer: leeches are ground pickups in the tall grass on Island 2 (Forest) — inland, not by the water. You need exactly three, and handing them to the lady by the lake gets you the Modified Leech, the bait that starts the Giant Piranha boss fight. They are not caught with a rod, no matter how long you fish the lake.
Start the Quest: The Lady by the Lake
On Island 2, find the lady sitting on the rock by the lake — walkthroughs place her northwest of the lighthouse, out on the Forest Island’s lake shore. Talk to her until her dialogue is fully exhausted: this is what arms the spawn table. Players who skipped the last dialogue beat have reported empty grass, so finish the conversation even if it feels over earlier.
Where to Find the Leeches
- Head inland, away from the shoreline. Guides are explicit: leeches sit in the tall grass on land, not near the water — searching the beach is the classic time-waster.
- Look for small dark wriggling spots in the grass and walk into them to pick up. Each character can carry them like any ground item.
- Optional: buy the Island 2 radar. Players report it paints each leech as a red dot, ending the grass-squinting entirely — worth it if you also want ground-item tracking afterwards.
- Collect three — the quest tracks 3/3, and anything extra is sellable meat.
- Return and hand all three to the lady — she forges the Modified Leech bait for the Giant Piranha summon.
Two outdated tips to ignore
Older guides and comments mention five leeches — the live quest counts 3/3, and extras are just meat.
And despite the name, you do not fish leeches out of the lake. They are land pickups; casting into the water for them wastes bait and time.
If Leeches Still Will Not Spawn
A dedicated forum thread covers the annoying case — dialogue done, grass searched, nothing. The community fix order:
- Re-talk to the lady completely — the spawn trigger is tied to finishing her dialogue, and partially-skipped conversations are the top reported cause.
- Reload your last save. Reports of “leeches stopped spawning after I died to the boss mid-quest” resolve on a reload — which is exactly why the save backup routine matters before boss attempts.
- Check co-op state. In multiplayer, pickups are shared world state — if a crewmate already grabbed a leech, the remaining spawns reflect what is left. A guest reconnecting with rolled-back inventory is a known pattern in our items triage guide.
What the Leeches Unlock
The hand-in is not the end — it is the gate to Island 3. The lady trades your three leeches for the Modified Leech, the only bait the Giant Piranha responds to. Casting it into the lake starts the fight; beating it drops the Giant Piranha skeleton, which walks back to the same lady for the Island 3 coordinates. The full phase-by-phase fight is in the Giant Piranha boss guide, and the whole progression ladder is on the islands page.
Leech Quest FAQ
Where do leeches spawn in How to Fish?
On Island 2 (Forest), in the tall grass inland — not at the water's edge. Multiple guides are explicit that leeches are land pickups found away from the lake, sitting in grass as small dark wriggling spots you pick up with the interact prompt. You need exactly three for the quest.
Why are no leeches spawning for me?
The most common cause reported on the forums: the quest had not actually started. Talk to the lady by the lake all the way to the end of her dialogue, then search again — new leeches spawn once her conversation is fully exhausted. If they still will not appear (some players hit this after dying to the boss mid-quest), reload your last save to reset the spawns.
Is there an easy way to spot leeches?
Buy the radar sold on Island 2 — players report it marks each leech as a red dot, which turns the hunt from pixel-hunting grass into following pings. It also tracks other ground pickups, so it stays useful after the quest.
Do I need more than three leeches?
No — the quest counts 3/3, and older guides saying five are outdated. Extra leeches you pick up along the way are just sellable meat, so there is no reason to hoard a fourth unless you want the pocket change.
