All villagers 5th face is the normal face, with their eyes closed:
But, as Chen have always his eyes closed there's no 5th face for him:
but example Felix and Mucho, we can't see their eyes but they make moves:
:He move the eyebrow
: He moves his mustache
I remember seeing one of the Uchos moving his nose, so I think the other brother and Chen also make moves when talking....
