A distinctive seed for Minecraft PE 1.1.0 and later versions of the game. This seed creates an underwater stronghold that can be thoroughly explored.

How to Locate the Underwater Stronghold

During world generation, ensure that all cheats are disabled in MCPE. After spawning, enter the command:
/locate stronghold
Then teleport using /tp @a -912 32 -1216
After this, you will arrive at a location featuring both the stronghold and the monument. Good luck to everyone!
