Peeper 

The most common fish found in the popular game Subnautica. It’s used as a few cover art and is mainly used on the website and steam page.

It’s a decent way to restore your hunger and isn’t too special when it comes to the thirst category.

Though it may seem like a starter food, peepers can be used throughout the entire game as emergencies or for other purposes, though there are usually other alternatives that can be better.
