It's happening!

  • Spawns in any ocean that isn't frozen
  • They're just cute, okay?

  • If you upset one, you upset them all
  • More behaviours coming soon

  • Water now only blocks 1 light per block, instead of 3
  • This only affects newly placed water - we will relight all chunks in an upcoming snapshot
  • Every ocean biome has a unique water colour, and swamps are icky and gross
  • In newly generated chunks, you're less likely to find frozen ocean next to warm ocean (and similar)



  • ????
  • I'm not sure.
  • What is this?
  • Where are we?

To get snapshots, open your launcher and go to the "launch options" tab. Check the box saying "Enable snapshots" and save. To switch between the snapshot and normal version, you can find a new dropdown menu next to the "Play" button. Back up your world first or run the game on in a different folder (In the "launch options" page).


Please report any and all bugs you find in Minecraft to bugs.mojang.com.


Snapshots can corrupt your world, please backup and/or run them in a different folder from your main worlds. 1.13 will have a lot of experimental snapshots that may break everything and smell funny. This may be one of those snapshots. This is what happens when Mojang are changing all the things!
