Edibile SeaWeed

I really like this idea because i thought Seaweed was in minecraft. Seaweed can grow right next to kelp. It can spawn in 3 difgerent ways. Short, medium and a bit long. You can use it like a ladder or vines to get down to the ocean floor. You take the seaweed and put it in the furnace. For fun make it a 1% chance you get poisioned form it because you just ate food off the ocean floor.
