I used a lure to catch bonito fish ( at Blue Deeps)
Spinner
You catch bigger fish
ok first you need a harpoon and a rope too go to the fishing guild and use rope on fishing spot then use harpoon on the fishing spot too and there you after 2mins or more you get it.
Use a Spinner in by the river and cast 90 ft
Go to waves of doom and use bait fish
Just tap the cast button so it's at about 19 feet and use bait fish. Fish at the old pond.
You go to breakwater and cast 120 feet, and use ragworm.
Waves of Doom. Use bait fish. Cast 210 ft.
Go to the River and fish at random lengths with luncheon meat. if u can, use the red fishing rod
I believe you can catch them in a few different places, but I just caught my last one at Lake Shiny
At waves of doom, use ragwort or lure and cast at random lengths. If you can, use the red fishing rod. It improves your chance of a collectible such as the mine
You use bait fish at lake shiny, 69 ft. Reset the tutorial for best results.
