Seagrass

Seagrass is a non-solid plant block that generates in all oceans, except frozen oceans.

Tall seagrass is a two-block high variety of seagrass.

Seagrass can be harvested only with shears. Using any other tool, item, or the player's fist destroys seagrass and causes it to drop nothing. When harvested with shears, regular seagrass drops itself as an item, and tall seagrass drops 2 seagrass items.
