I had an idea. Maybe There would be a fishing pole item, and you click to cast, and maybe say something like z to real in. Then there would be special water bricks, that contain small fish models, and when the line comes within a certain area, the fish would mount the line, and the pole would like bend. Then you reel in, and you got a fish! that would be a fun gamemode, or just a flat out mod like copymod.
