It could be a glitch becuase monsters will drink water alot if hungry to regen health maybe meaning they accidentally made him do that, and yes it is odd but yian kut ku, lunastra, gravios, maybe basarios, and teostra will all eat coal. I am really 100% sure for kut ku after reading in mhf in the volcano he eats coal.
