Fhiskerland

The main character, Fhisk, he's this little 7 year old dude (pre-ts) who goes fishing with his dad every day cuz his dad is called the Fishing God which basically means he's the strongest and most best fisherman in the world. but they later find out that there's this organization that takes fish and remakes them as monsters/weapons to do harm to those that think their ”laws" are bad. so then they challenge this organization by becoming true fisherman and they go out to save fishes.
