Apkallu is this really weird creature form the far east :) Has an eagle head, the body of a fish, and wings!!!! I'm not making this up :) Also appearently, this was incredibly scary back in those days :)
Karaconcolos is another favorite of mine from the MOB section. According to Wikipedia, nobody knows what they look like. Even in the same household people will tell different things about what a Karaconcolos looks like. So I decided I make them this kind of bee hive, constantly shifting mass.
