Questions

How far is the ocean monument from the mushroom island?

About 165 blocks north. The monument is at 80, 63, -176 and fills the sea floor between y 39 and 61, so you can see its outline from above the water.

Is there land near the mushroom island?

Yes. A savanna coast with grassy cliffs and acacia trees lies to the east and south-east of the island, across the water.

Does this seed work on Bedrock or other versions?

We verified it only in Java 26.3. Bedrock and other Java versions may generate a different world from the same seed.
