M̶e̶s̶s̶a̶g̶e̶ Banner Pattern In A Bottle

Have you been frustrated by trying to get a certain type of banner pattern? do you like fishing? I have an answer for you. Banner Patterns in a bottle, kind of like a message in a bottle.

A B.P.B would be added to the treasure category of fishing to give a little more variation to the exciting reels you can pull in, acting like a bottle o enchanting upon being thrown, except instead of xp, you get a random banner pattern, you could also add a few new exploration/ sea themed patterns, such as a Crescent Moon, or a Compass Rose.
