he's had this previously except the thing was a lot thicker. it just crumbles away when you touch it L, like as if it's dirt, but it's growing out of this hole in his skin on a piece of hair? the loss of hair around it is from me trying to pull it... I've pulled it before after it crumbled because I thought it was just just a dirty hair and it went away but it's back and it's coming from this hole... he also seems to have like a little bit of a mound or bump under his skin, but not exactly like that, where the hole is. has anyone seen this before? I can't find anything on the internet about this!
