Mushroom Fields only form far out in the ocean, so they are rarely near spawn. Hostile mobs do not spawn there naturally, which makes them a safe place for a base, and Mooshrooms live there.

In Java Edition, click “Create New World”, open the “World” tab and paste 4083710742383724680 in the “Seed for the world generator” field. The coordinates on this page are only valid in Java Edition.
No. Bedrock Edition places structures differently, so the same number gives another world. All seeds on Blockaria are Java seeds.
All seeds on Blockaria were found by our own search tool, not copied from other lists. Biomes and structures are computed with cubiomes by Cubitect (MIT licence), a version we froze for 26.1 and 26.2, plus the 26.3 Dappled Forest rule. Coordinates are the starting chunk of each structure (within 16 blocks); heights are confirmed in game. Map: Chunkbase.
