The Fishing Pole is a key item used for catching fish.
|A reliable fishing pole. Use it to land fish from bodies of water.|
Select the Fishing Pole, stand near any water body and press the action button. You will enter the fishing mini-game (there is a quick tutorial first time you do that). After the fish you need spawns get your bobber in front of it so it can bite. After the fish bites reel it in by dragging the bobber in the direction opposite of its movement.
Every fish in the game must be caught with a pole.
