Mushroom island off a savanna coast, with an ocean monument and trial chambers
A small mushroom island with giant red and brown mushrooms sits in clear sea off a savanna coast, with an ocean monument to the north.
About this world
This seed has a small mushroom island at 38, 63, -14, close to 0, 0. Giant red and brown mushrooms grow on its purple-grey mycelium, and the sea around it is clear enough to see seagrass on the bottom. To the east and south-east, a savanna coast rises in grassy cliffs dotted with flat-topped acacia trees.
An ocean monument lies on the sea floor at 80, 63, -176, about 165 blocks north of the island, and its outline shows through the water from above. Trial chambers are underground at 96, -20, 128, about 155 blocks south of the island. A shipwreck lies on the sea floor near 0, 63, 240, about 150 blocks south-west of the trial chambers. Seeder lists this world on its Mushroom Fields page.
