Seagrass

Sea grass is a non-solid plant block that generates in all oceans except frozen oceans.

Obtaining
Sea grass can be obtained with shears. If mined with any other tool or the player's fist, it will drop nothing.

Turtles
Turtles will drop 0–2 sea grass when killed. The Looting enchantment will increase the maximum number of possible sea grass drops by 1 per level.

Natural generation
Sea grass generates in either its tall or small form in ocean biomes near kelp, and will also generate in rivers and swamps by itself.

Bone meal
Using bone meal underwater will generate sea grass. The bone meal must be used on a non-transparent block under at least 2 blocks of water, with the water directly above the block being non-flowing. If these conditions are met, a one-block tall sea grass will generate on that block, and if available, sea grass will also generate on surrounding blocks.

Usage
The sea grass item can only be placed on non-transparent blocks.

Breeding
Sea grass can be used to breed turtles.

Bone meal
Applying bone meal to a one-block-tall sea grass will turn it into a two-block-tall sea grass.
