My idea that i think should be implemented into minecraft is the idea of new water mobs. My friend and I have been discussing this fir quite some time now. The new mobs should include: plant life, the fish that you can catch with the fishing pole, new kinds of fish so that the fish that you can catch varies, sharks (hostile mob), jelly fish(can sting you), seashells, stingrays (also can sting you), dolphins, and crabs. I hope you can take these ideas into consideration.
Thank you
