This mod adds two new world types that can be selected the same way as ?Default’, ?Super Flat’ and ?Large Biomes’. These new world types mess with the terrain generation to give an interesting terrain to those bored with the normal Minecraft one. This will not conflict with any mods!
The New World Types:
Crazy Chunks: The original crazy terrain for Minecraft!
Spiky Chunks: The least crazy but the fastest loading of these world types
