Cryosol

This is a variant of a grass block that can have most plants on it, but players take freezing damage on walking in this block. This block generates on the borderline between cold biomes and temperate biomes. Plants on this block may become a frosted version, preventing them from bone meal being used on them.

This block may spread slowly to grass blocks without snow layers on top in cold biomes.

Villagers from icy biomes do not take damage on walking in this block, as their clothes are designed for the cold.
