Complete Earthbending- Coalbending

In Avatar: The Last Airbender, Book 1, Chapter 6: "Imprisoned":
It shows us how Huru and his father were able to bend "coal"

I'm not suggesting a move, I am just suggesting that there should coalbending (people start suggesting coalbending moves)

I think coalbending should be bendable in source blocks or the actual coal in your inventory (just like metalbending)

Coalbending is shown in the end of the video

I also made an example:

Simply add Coal to the Earthbendable blocks in the config!
