13, also known as the Update Aquatic, is a major update to Java Edition that was released on July 18, 2018. It focuses mainly on ocean content and technical features. This update was originally intended to be released as two separate updates with 1. 13, originally named Technically Updated, having the technical changes and 1. 14, originally named Update Aquatic, having all the ocean features, however they were combined into one big update.

13 was scheduled to be released on May 30, 2018. However, the release was pushed back to July 18, 2018 to fix critical bugs. Both have the exact same properties as air. More slippery than ice and packed ice.

Must be mined with a Silk Touch tool in order to drop itself, otherwise they drop a dead coral block. Turns into a dead coral block if none of its six sides are touching water, although not instantly.
