Sea pickle farm blocks
If sea pickles are planted on coral blocks, using bone meal on the sea pickles increases the number of sea pickles and creates more sea pickles on nearby coral blocks. Specifically, they can spread to the original sea pickle's level or one level below, out to a horizontal taxicab distance of 2. This is the only way to farm renewable sea pickles.

Dead coral blocks
In order for a coral block to stay alive, at least one of the six directly adjacent blocks must be water. If placed outside of water, it transforms into its respective dead coral block after a few seconds &mdash; a grayscale version of the coral block.
