Sometimes Loki likes to obsessively lick Yun, as if Yun were a human salt lick. I find it really amusing, mostly because Loki almost never does this to me. So I an laugh at Yun for being Loki's salt lick. Haha! The interesting thing is that Loki typically doesn't lick people much. Jujube is the one that tends to lick people when she greets them, but she doesn't lick obsessively.
