Frozen Dirt and Frozen Mud (Block)

I was thinking of a frozen variation of vanilla Dirt and Mud.

Frozen Mud would naturally spawn at the bottom of the frozen ocean in the Ice Spikes biome, look different from its default counterpart, and have new sounds.

New mechanics: If the player surrounds the mud with ice blocks from all sides, Ice, Packed Ice, or Blue Ice, the normal mud will turn into frozen mud after a certain amount of time. Normal Ice blocks take the longest, and Blue Ice takes the fastest.

To restore the normal mud, the player must place the frozen mud in a furnace.

Frozen Dirt could be found everywhere in biomes like Snowy Beach, Snowy Plains, Snowy Slopes, and Snowy Taiga.

It'd have a different texture and new sounds as well.

New mechanics are the same as with Frozen Mud.
