Tiny demon/angel guy?

WIP doodle ideas for a character for a very undeveloped story
He's like a rock elemental demon who eats rocks, yum yum
But he's also an adorable innocent choir boy who just wants to help everyone and hug the world
He died at some point and didnt really notice.
"Demons?! Aaaa, scary!! Where are they??"
*eats rocks like a normal human*
