About this world

This seed puts an ocean monument at -208, 63, 240, in shallow blue-green water full of seagrass. Its square outline shows through the surface from above. A jungle coast lines the water to the west, and an island of giant red and brown mushrooms sits to the north.

The mushroom fields point is at -326, 63, -2, about 270 blocks north-northwest of the monument, on grey mycelium hills with steep dirt edges. An ocean ruined portal lies on the sea floor at -288, 63, 304, about 100 blocks southwest of the monument. Trial chambers are underground at -224, -40, 144, about 95 blocks north of the monument. Seeder lists this world on its Monument / Mushroom Fields page.
