About this world

The checked mushroom fields point at 46, 63, 426 lies offshore beside gray land with red and brown mushrooms. The northern and wider views show the land edge across open water. Farther northeast, the ocean monument near 192, 63, 160 is visibly cyan below the sea surface, with its generated structure spanning y 39–61.

Trial chambers below 192, 256 were inspected at y -38. Their northern screenshot shows part of a copper-and-tuff pillar room in spectator mode, with terrain clipping around the edges. The ocean portal near 304, 63, 352 was confirmed at y 50–59, but the overhead view only offers a faint seabed patch; the portal frame is not clearly resolved.

How to get there

In Java Edition 26.3, choose Create New World, open the World tab and enter seed -963374613974828980.
Set Game Mode to Creative or turn Allow Cheats on, and press F3 to show your coordinates.
Run /tp @s 46 98 356 0 26.6 to see the mushroom fields shore from the gallery viewpoint.
For the monument, run /tp @s 192 98 160 and look through the sea surface at its cyan outline.
For the trial chamber pillar room, run /gamemode spectator, then /tp @s 191 -38 257. The photograph is a cutaway with clipping at its edges.
The portal lies below 304, 63, 352, between y 50 and 59. Inspect beneath that surface anchor in spectator mode; the overhead gallery does not show a clear frame.

Questions

Is the mushroom fields coordinate on the shore?

The checked point at 46, 63, 426 is offshore. Gray mushroom-covered land appears nearby in the northern and wider photographs.

Can I see the ocean monument through the water?

Yes. The southern photograph shows the cyan monument below the surface near 192, 63, 160. Its generated blocks span y 39–61.

What is shown in the underground chamber image?

Part of a copper-and-tuff pillar room is visible near y -38. The spectator camera clips through terrain around the room edges; the image does not establish a surface entrance.

Does this seed work on Bedrock or other Java versions?

We verified this world only in Java 26.3. Bedrock and other Java versions may generate different terrain and structures from the same seed.
