Mina the Hollower Fishing Guide: Hook, Line, And Sinker

Before you waste three hours scouring the map for hidden paths, you need to realize fishing is entirely optional but absolutely worth the effort for the bragging rights alone.

You can easily beat the main story without ever holding a fishing rod. Tenebrous Isle is packed with enough hazards to keep you busy, but grabbing all 16 unique fish earns you the Fishin' Reactor trophy from Durwin. Getting started is not exactly obvious since the rod is tucked away off the main path.

If you are also hunting down other collectibles to maximize your survival odds, check out my comprehensive guide on where to find every trinket. You will need all the help you can get out there.

How To Snag The Fishing Rod

Before you can start yanking weird aquatic mutants out of the muck, you have to actually find Irwin. He hangs out at the Fishing Hole in the Backwaters. Getting there requires a short trek through some nasty territory.

Head to the Occupied Bridge in the Western Wilds, which is just northwest of Ossex. Run all the way left past the lava and enemies, then head south into the Shanty Swamp. Keep pushing south through the swamp until you hit a signpost. Head east into the next screen to find the Fishing Hole. Talk to Irwin and the rod is yours.

Using it costs 3 Joules a pop. You just press your action button to cast, press it again to stop the bobber over a shadow, and then reel your catch in. Easy enough, right?

Upgrades And The Angler's Raft

You only get one true upgrade for the rod itself. Once you hand over all 16 fish to Durwin at the Fishing Hole, he forks over the Gilded Rod. It lets you cast significantly farther, which is a nice flex even if you already finished your collection.

The real game changer is a Sidearm called the Angler's Raft. This throws down a floating plank of wood that lets you stand directly on water for a brief window. It makes positioning for tricky catches infinitely easier.

To find it, make your way to Sandfalls: Shifted Sands. Near the stairs leading to Bone Beach, check the left area for a suspicious wall. Blow it open with a bomb, use a kear to navigate the next room, and pop open the chest inside to claim your raft.

All 16 Fish Locations

I threw every fish location into a neat list below. Any fish you catch automatically goes to the trophy shelf back at the Fishing Hole.

Some regions are a bit messy, so check every puddle and dirty stream if a shadow is not immediately obvious.

Fish Name	Location Details
Crumblefin Head	Southern Outskirts: Commons. Look in the ponds near the Cave Network entrance and the newspaper reading NPC.
Cuddlepus Shell	Radiant Manor: Dining Room. Also spotted near the lava pools in Western Wilds: Occupied Bridge.
Dork Eyes	Eastern Heath: Grassland. Hook it from the water under the bridge heavily guarded by flying enemies.
Fishcicle Core	Coltrane Peak: Rail Yard. Walk past the snowman at the northern edge to find a freezing pool.
Fleeper Head	Backwaters: Fishing Hole. Cast your line exactly where you found Irwin.
Gazeworm Eye	Septemburg. Look for a puddle in Crow Town near the Windy Generator.
Glomper Stalk	Western Wilds: Occupied Bridge. Cross the lava and run south to a dead end. Fish the puddles right before the Backwaters entrance.
Goremaw Fang	Bone Beach: Bone Rush Trail. Just cast your line straight into the ocean.
Puffer Beak	Sandfalls: Shifted Sands. Enter the brazier room, turn around, smash the breakable wall, and check the secret puddle.
Shrimpter Tail	Nox's Bayou: Boat Bog. Swim over and fish near the large boat.
Spincer Pincers	Septemburg: Wastewater Canal. Cast right near the entrance of the area.
Tombstone (Ghost Fish)	Queensbury Crypt. Pass the spiked traps in the entryway, head right, and fish in the dirty green water.
Trigger Antennae	Radiant Manor: Chamber. You can also hook this one next to the anchored ship at Loner's Landing: Blighted Docks.
Triple Flagellum	Ossex City Center. Check the water near the bridge right by the Music Hall.
Trunkstar Core	Astral Orrery: Mirror's End. Found swimming in the room with the giant knight.
Thalassion Pearl	Backwaters: Fishing Hole. Head east from the main hole and use your rod on an enemy to swing across to an elevated ledge. Defeat the Thalassion boss and head back to Irwin's spot to claim the trophy.
