Fishing

Basics
If you have at least one in your inventory and/or in your arms, you can use to try and catch some fish (or other stuff).

Currently, there are two spots available to do so, one on the shore in the south-eastern part of the Abandoned Town (near the old warehouse), and one in the Forest Park. In order to start fishing, you can just go to the marked spot, and interact with it. You can fish for as long as you want, there's no upper limit or stamina penalty.

Fishing
Your chance to catch something successfully is $30 + [Sen] × 4%$ (Sen18+) without bait, and $60 + [Sen] × 4%$ (Sen10+) if you use. If you fail the Senses check, you would catch nothing.

During Farm repopulation, while fishing in the Forest Park, you can randomly catch something more interesting than mere fish...
