Sea Pickle

Sea pickles are light-emitting plants found underwater.

Obtaining
A sea pickle will break instantly and drop itself as an item if broken using anything, or if the block below it breaks, dropping as many pickles as there are on the block.

Natural generation
Sea pickles can generate in warm oceans and lukewarm oceans, either spawning nearby coral, or on top.

Usage
Sea pickles can be placed on top of most solid blocks, up to four per block, similarly to turtle eggs. They produce light when underwater, each additional pickle adds 3 light levels.

Bone meal may be used on sea pickles, causing them to spread if underwater and on top of any kind of coral block. Bone meal does not grow them if they are on land.

Trivia

 * They appear to be based on sea pickles, a real-life tunicate with blue-green bioluminescence.
