Random Block Chunks
Generates every chunk out of a randomly chosen block.
⬇ Download on CurseForgeThe author built this one for Minecraft 1.20–1.20.1 on Fabric. On other versions it may install and then do nothing.

This mod makes it so each chunk in your Minecraft world will consist of one random block.
The only Blocks that stay how they "should" be are Bedrock, End Portal Frames and Spawners to make reaching the End possible, though wood chunks in the Nether are a interesting addition to that journey. ;)
Note that not all blocks are able to generate. Blocks with gravity and TNT for example have been excluded, so they don't cause performance issues.
