Sea Pickle

Sea pickles are light-emitting colonies of small stationary animals found underwater.

Obtaining
Sea pickles can be broken instantly. Each colony drops 1-4 sea pickles, depending on how many are in the colony (so a colony of 3 pickles drops 3 pickles).

Natural generation
Sea pickle colonies generate on the bottom of warm oceans and are found on top of coral blocks in coral reefs. Each chunk has $1/6$ chance to generate sea pickle colonies. They can be found in groups of 1 up to 4.

Sea pickles may also be found in desert village houses as decorative blocks.

Post-generation
Using bone meal on a sea pickle placed on top of a coral block creates more sea pickles. Specifically, the colony to which bone meal is applied increases in size, and any coral block in a 5x5 area (except the corners) can generate 1-3 sea pickles. They do not grow or spread naturally, and do not require light.

Trading
Sea pickles are sold by wandering traders for 2 emeralds.

Usage
Sea pickles can be placed on top of most solid blocks, as well as non-solid blocks, up to four per block, similarly to turtle eggs. More information regarding placement on transparent blocks can be found at Opacity/Placement.

Sea pickles produce light when underwater. A single pickle produces a light level of 6, and a colony produces an additional 3 levels per pickle (so 4 sea pickles produces a light level of 15). When they produce light, there is a pale green glow at the end of the pickle.

Bone meal can be on sea pickles if they are underwater, and planted on living coral blocks. This increases their number on that block, and they spread to empty areas underwater above other living coral blocks. They can spread to the original sea pickle's level or one level below, out to a horizontal taxicab distance of 2. Bone meal can be used on sea pickles planted on other blocks, or outside of water, but nothing happens and the bone meal is still consumed.

Composting
Placing a sea pickle into a composter has a 65% chance of raising the compost level by 1.

Trivia

 * Sea pickles are real-life tunicates with blue-green bioluminescence, more properly known as pyrosomes.
 * Sea pickles can generate in desert village houses to resemble cups, mugs, or miniature pottery.
