I think if the dam cracked open and flooded lake opening up a giant ocean for players to fish on would be crazy. there could be a kraken boos fight if you went into his terratory. Some fish you could catch would be a crab, crystal crab, shark, the meg(boss fight-ish), stingray, Lantern fish, and more. This would be super fun and would be a lot of exploring, You could also go scuba diving to spear fish or just explore coral reefs. with bones you could by boats that get better and better. some of the better fishing boatss would have stands to put fishing rods on while you wait for fish to bite. and if you dont have a boat then you can just fish or swim on the beach with your freinds while saving for one.
I think this would add a lot of cool things to animal company and my freinds and randoms told me this would be cool.
Please consider what I said
