FishMe is an optional mod that adds a "perfection bonus" to the Fish.

The bonus is triggered during the Stardew Valley Fair minigame, and it is based on your configurable setting.

You can turn the bonus off or on, and you can also decide whether you want to receive the bonus every time you fish or only on your catch days.

This mod also adds a new configurable option to always catch treasures, which will allow you to receive a free treasure every time you fish.
