What you typed
an ocean mine
The offline reader calls this Ocean Mine. The size is big. Walls are prismarine bricks, the roof is dark prismarine, and the trim is prismarine. No height was set, so the plan uses its usual height for this size. It is built from parts. The shape on the recipe is “mine”, which only names the stock plans.
This build has 3,315 blocks, 3,315 of them solid. The three most common are sand (1,223), prismarine (694), oak leaves (366). Watch plays for 46 seconds, the length of this build’s timelapse. The seed is 1742892558, taken from the sentence, so the same words build the same thing offline. It is built from parts. The shape on the recipe is “mine”, because that field only names the stock plans.
