Busy

The Biome called "Busy" was a biome released in Minecraft snapshot 20w14∞ for April Fools. The biome features what may look like a Snowy Taiga Biome, but the biome has random placements of blocks such as Iron Blocks, Redstone Blocks, etc.

Weird Blocks
The blocks that spawn either on the surface are kind of weird, not all being to their respective tile, and sometimes being random at times.
